Opis:
This paper investigates the conceptualization of the gene in the book The Selfish Gene by Richard Dawkins from the point of view of the Conceptual Metaphor Theory and the Conceptual Blending Theory. It is argued that there are two senses of the gene: gene1 is a physically existing section of the DNA, gene2 is information about protein synthesis. It is the second sense of the concept of the gene that undergoes metaphorization. The analysis reveals that Dawkins’ gene is a conceptual blend which becomes extensively elaborated. Through elaboration the gene becomes personified on the one hand and deified on the other. The study shows the richness of Dawkins’ personification: the gene is conceptualized as building and controlling organisms, cooperating and competing with other genes, even showing personality traits. Deification of the gene is focused on highlighting its stipulated immortality and power to create organisms, humans included. The gene blend is at the same time used as an input space in the integration network producing the meme blend. It is also established that the personification of the gene plays the theory-constitutive role in the sense of Boyd (1993).

Opis:
This short review attempts to demonstrate the usefulness of antiangiogenic gene therapy in achieving inhibition of growth in experimentally-induced metastases. Certain normal tissues (for example skeletal muscle) may be used in vivo, after genetic modification, as a "bioreactor", able to produce and secrete into the bloodstream proteins known to exert antiangiogenic effects. By inhibiting neoangiogenesis these proteins would thus prevent the development of metastases. The review discusses also the perspectives of antimetastatic therapy based on certain types of allogenic cells (for example myoblasts and fibroblasts) that had been genetically modified and then microencapsulated. The strategy of encapsulation is aimed at protecting the modified cells secreting antiangiogenic factors from being eliminated by the immune system. Secretion of antiangiogenic proteins by these microencapsulated cells can be controlled with inducible promoters. Antiangiogenic genes remaining under the transcriptional control of such promoters may be switched on and off using antibiotics, such as tetracycline derivatives, or steroid hormones.

Opis:
The paper presents data mining methods applied to gene selection for recognition of a particular type of prostate cancer on the basis of gene expression arrays. Several chosen methods of gene selection, including the Fisher method, correlation of gene with a class, application of the support vector machine and statistical hypotheses, are compared on the basis of clustering measures. The results of applying these individual selection methods are combined together to identify the most often selected genes forming the required pattern, best associated with the cancerous cases. This resulting pattern of selected gene lists is treated as the input data to the classifier, performing the task of the final recognition of the patterns. The numerical results of the recognition of prostate cancer from normal (reference) cases using the selected genes and the support vector machine confirm the good performance of the proposed gene selection approach.

Opis:
The paper presents the ensemble of data mining methods for discovering the most important genes and gene sequences generated by the gene expression arrays, responsible for the recognition of a particular type of cancer. The analyzed methods include the correlation of the feature with a class, application of the statistical hypotheses, the Fisher measure of discrimination and application of the linear Support Vector Machine for characterization of the discrimination ability of the features. In the first step of ranking we apply each method individually, choosing the genes most often selected in the cross validation of the available data set. In the next step we combine the results of different selection methods together and once again choose the genes most frequently appearing in the selected sets. On the basis of this we form the final ranking of the genes. The most important genes form the input information delivered to the Support Vector Machine (SVM) classifier, responsible for the final recognition of tumor from non-tumor data. Different forms of checking the correctness of the proposed ranking procedure have been applied. The first one is relied on mapping the distribution of selected genes on the two-coordinate system formed by two most important principal components of the PCA transformation and applying the cluster quality measures. The other one depicts the results in the graphical form by presenting the gene expressions in the form of pixel intensity for the available data. The final confirmation of the quality of the proposed ranking method are the classification results of recognition of the cancer cases from the non-cancer (normal) ones, performed using the Gaussian kernel SVM. The results of selection of the most significant genes used by the SVM for recognition of the prostate cancer cases from normal cases have confirmed a good accuracy of results. The presented methodology is of potential use for practical application in bioinformatics.

Opis:
Recently, data on multiple gene expression at sequential time points were analyzed using the Singular Value Decomposition (SVD) as a means to capture dominant trends, called characteristic modes, followed by the fitting of a linear discrete-time dynamical system in which the expression values at a given time point are linear combinations of the values at a previous time point. We attempt to address several aspects of the method. To obtain the model, we formulate a nonlinear optimization problem and present how to solve it numerically using the standard MATLAB procedures. We use freely available data to test the approach. We discuss the possible consequences of data regularization, called sometimes "polishing", on the outcome of the analysis, especially when the model is to be used for prediction purposes. Then, we investigate the sensitivity of the method to missing measurements and its abilities to reconstruct the missing data. Summarizing, we point out that approximation of multiple gene expression data preceded by SVD provides some insight into the dynamics, but may also lead to unexpected difficulties, like overfitting problems.

In the paper the detection of the SSCP polymorphism within the 5’ fragment of bovine beta-lactoglobulin (LGB) gene is described. The 5’ fragment of LGB gene (209 bp) was PCR-amplified and then subjected to electrophoresis allowing the detection of SSCP polymorphism. Among 124 animals (50 cows and 74 bulls) six SSCP patterns were identified and named Rl, R2, R3, R4, R5 and R6, which occured with the frequency of 0.32, 0.51, 0.09, 0.06, 0.01 and 0.01, respectively. The PCR-SSCP method is simple, fast, and relatively inexpensive. The SSCP polymorphism reported in the paper may be useful in looking for the associations between different SSCP patterns and LGB gene expression and milk properties.

Opis:
Background. Our previous studies have shown that short-term treatment with phenobarbital (PB) resulted in cytosine methylation of CpG sites on the p53 gene promoter in male Wistar rats’ liver. Furthermore, PB induced DNA-methyltransferases (DNMTs) activity was also demonstrated; being the enzymes that catalyze methyl group transfer to cytosine in CpG dinucleotides. Objective. Since DNA methylation is involved in regulating gene transcription and that DNMT1 is implicated in regulating DNA methylation, this study assessed whether PB-induced hypermethylation of the p53 promoter region was associated with an altered expression of p53 and Dnmt1 genes. Material and methods. Male Wistar rats received PB in three daily oral doses (at 24-h intervals) of 92,8 mg/kg b.w. x day-1. Levels of mRNA for p53 and Dnmt1 and levels of relevant proteins were respectively examined by Real-Time PCR and Western blot analysis. Results. Gene expression analysis revealed that exposure of Wistar rats to PB caused statistically significant alternations in the expression of tested genes. We found that both mRNA and protein expression of p53 was down-regulated, whereas expression of Dnmt1 (both mRNA and protein) was up-regulated after PB treatment. Conclusions. Suppression of p53 mRNA and protein expression, which is probably a result of epigenetic changes, (in particular aberrant p53 promoter hypermethylation), can be associated with tumour promoting activity of phenobarbital.
Wprowadzenie. Nasze wcześniejsze badania wykazały, że krótkoterminowe narażenie szczurów Wistar na fenobarbital (PB) stymulowało metylację cytozyny w badanych sekwencjach rejonu promotorowego genu p53. Ponadto stwierdzono wzrost aktywności metylotransferaz DNA (DNMT), enzymów które katalizują przenoszenie grupy metylowej do cytozyny w dinukleotydach CpG. Cel badań. Z uwagi że metylacja DNA pełni istotną rolę w ekspresji genów, a DNMT1 uczestniczy w regulacji metylacji DNA, w prezentowanych badaniach oceniano czy indukowana PB hipermetylacja rejonu promotorowego genu p53 była związana ze zmianami ekspresji genów p53 i Dnmt1. Materiał i metody. Samce szczurów szczepu Wistar otrzymywały PB w dawce 92,8 mg/kg m.c. x dzień-1, 3-krotnie w odstępach dobowych. Analizę poziomu transkryptów i białek badanych genów przeprowadzano odpowiednio metodą Real- -Time PCR i Western blot. Wyniki. W wyniku oddziaływania PB wykazano obniżoną ekspresję genu p53 i wzrost ekspresji metylotranserazy 1 (DNMT1). Wnioski. Supresja ekspresji p53 (na poziomie mRNA i białka) będąca prawdopodobnie wynikiem zmian epigenetycznych, w szczególności hipermetylacji jego rejonu promotorowego może być związana z promocyjną aktywnością fenobarbitalu.

We investigated the feasibility of transferring naked plasmid DNA containing a therapeutic gene (IL-12) into mice harboring growing Renca tumors. We found that naked DNA transferred into growing Renca and B16(F10) tumors gives higher expression level of reporter gene than complexes of DNA with DDAB/ DOPE or DC-Chol/DOPE. Transfer of naked DNA carrying the IL-12 gene into growing Renca tumors causes a distinct therapeutic effect that depends on the time span between inoculation of mice with cancer cells and the beginning of the therapy. Therapy started on day 3 resulted in total cure (100%) of mice.

Opis:
This review focuses on plant-to-plant horizontal gene transfer (HGT) involving the three DNA-containing cellular compartments. It highlights the great incidence of HGT in the mitochondrial genome (mtDNA) of angiosperms, the increasing number of examples in plant nuclear genomes, and the lack of any convincing evidence for HGT in the well-studied plastid genome of land plants. Most of the foreign mitochondrial genes are non-functional, generally found as pseudogenes in the recipient plant mtDNA that maintains its functional native genes. The few exceptions involve chimeric HGT, in which foreign and native copies recombine leading to a functional and single copy of the gene. Maintenance of foreign genes in plant mitochondria is probably the result of genetic drift, but a possible evolutionary advantage may be conferred through the generation of genetic diversity by gene conversion between native and foreign copies. Conversely, a few cases of nuclear HGT in plants involve functional transfers of novel genes that resulted in adaptive evolution. Direct cell-to-cell contact between plants (e.g. host-parasite relationships or natural grafting) facilitate the exchange of genetic material, in which HGT has been reported for both nuclear and mitochondrial genomes, and in the form of genomic DNA, instead of RNA. A thorough review of the literature indicates that HGT in mitochondrial and nuclear genomes of angiosperms is much more frequent than previously expected and that the evolutionary impact and mechanisms underlying plant-to-plant HGT remain to be uncovered.

Opis:
In the majority of potential applications gene therapy will require an effective transfer of a transgene in vivo resulting in high-level and long-term transgene expression, all in the absence of significant toxicity or inflammatory responses. The most efficient vehicles for delivery of foreign genes to the target tissues are modified adenoviruses. Adenoviral vectors of the first generation, despite the high infection efficacy, have an essential drawback: they induce strong immune response, which leads to short term expression of the transgene, and limits their usefulness in clinical trials. In contrast, helper-dependent adenoviral vectors (HdAd) lacking all viral coding sequences display only minimal immunogenicity and negligible side-effects, allowing for long-term transgene expression. Thus, HdAd vehicles have become the carrier of choice for adenoviral vector-mediated experimental gene therapy, effectively used in animal models for delivery of transgenes into the liver, skeletal muscle, myocardium or brain. Strong and long-lasting expression of therapeutic genes has allowed for successful treatment of dyslipidemias, muscular dystrophy, obesity, hemophilia, and diabetes. Additionally, the large cloning capacity of HdAd, up to 37 kb, facilitates the use of physiologically regulated, endogenous promoters, instead of artificial viral promoter sequences. This enables also generation of the single vectors expressing multiple genes, which can be potentially useful for treatment of polygenic diseases. In this review we characterize the basic features of HdAd vectors and describe some of their experimental and potential clinical applications.

Opis:
The term “gene” was originally used as a purely theoretical concept. After discovery of DNA structure, and understanding the genetic code, the gene acquired a form of a distinct physical entity with its borders and specific signal sequences, having rather simple (as it was thought at that time) functions and relation to phenotype outcome. The term “structural gene” has been coined. The unique gene structure, and several unusual and omnipotent traits have been ascribed to the gene that resulted in the formulation of a “genocentric” theory as a basic expla nation of all features of living organisms. However, recent discoveries reveal a complex structure and functions of eukaryotic genes. It appears now that the coding sequences (exons) are spread out over extended regions (hundreds of thousands of kilobases) of DNA. The role of protein-non coding DNA sequences were recognized, and the new mechanisms controlling gene functions have been discovered. In addition, we acquired the knowledge about a powerful ability of the cell to interpret the information potential of genes, accordingly to the needs of a cell/organ or actual “context” and status of the dynamic systems operating within the cell. All these discoveries undermine the genocentric view of life. At this time any definition of “gene” seems to be inadequate with present knowledge, and one may ask again: what is a gene?

Two recent studies found that RBMS1 gene rs7593730 and BCAR1 gene rs7202877 are related to type 2 diabetes. However, the association of these loci with type 2 diabetes mellitus (T2DM) has not been examined in Chinese. We performed a replication study to investigate the association of the 2 susceptibility loci with T2DM in the Chinese population. We genotyped 1961 Chinese participants (991 with T2DM and 970 controls) for each of the 2 single nucleotide polymorphisms (SNPs) rs7593730 in RBMS1 and rs7202877 near BCAR1 using SNPscan and examined their association with T2DM using logistic regression analysis. We also analyzed the correlation of the SNP alleles and clinical phenotypes. In additive model, genotype association analysis of BCAR1 rs7202877 loci revealed that the homozygous of rs7202877 GG carriers had significantly decreased T2DM risk compared to homozygous carriers of TT (P=0.038, OR 0.44, 95% CI 0.20-0.96). In the recessive model, the GG genotype GG had significantly decreased T2DM risk compared to GT+TT (P=0.043, OR 0.67, 95% CI 0.46-0.99). Allele G was statistically significantly correlated with TC (mmol/L) (P=0.036) and LDL-C (mmol/L) (P=0.007). As for rs7593730, the carriers of CT and TT genotype had significantly decreased T2DM risk compared to the carriers of CC genotype (CT: CC P=0.038, OR 0.71, 95% CI 0.51-0.98; TT: CC P=0.010, OR 0.32, 95% CI 0.13-0.76). In a dominant model, TT+CT: CC (P=0.013, OR 0.673, 95% CI 0.49-0.92) and in a recessive model, TT: CT+CC (P=0.019, OR 0.59, 95% CI 0.39-0.92). The T allele carriers had significantly decreased T2DM risk compared to the carriers of C (P=0.002, OR 0.65, 95% CI 0.50-0.86). Allele T was statistically correlated with FINS (P=0.010). In conclusion, our study showed that RBMS1 gene rs7593730 and BCAR1 gene rs7202877 were significantly associated with type 2 diabetes in the Chinese population.

This classification system was established by comparing full or nearly full gene sequences, > 2000 bp. For practical reasons, diagnostic fragments of smaller lengths have been identified and used for rapid and economic identification of large number of strains. While the use of these small fragments in diagnostics applications remains valid when and only if the reference full sequence-type is available, we contest their use to identify and describe new genotypes. We report herein the case of a new genotype described on the basis of solely a small partial sequence and discuss the poor reliability of this fragment to correctly infer phylogenetic relationships, and its limits in the description of new genotypes of Acanthamoeba.

Opis:
Recently, data on multiple gene expression at sequential time points were analyzed, using Singular Value Decomposition (SVD) as a means to capture dominant trends, called characteristic modes, followed by fitting of a linear discrete-time dynamical model in which the expression values at a given time point are linear combinations of the values at a previous time point. We attempt to address several aspects of the method. To obtain the model we formulate a nonlinear optimization problem and present how to solve it numerically using standard MATLAB procedures. We use publicly available data to test the approach. Then, we investigate the sensitivity of the method to missing measurements and its possibilities to reconstruct missing data. Summarizing we point out that approximation of multiple gene expression data preceded by SVD provides some insight into the dynamics but may also lead to unexpected difficulties.

The Czech winter wheat cv. Regina which does not possess specific genes for powdery mildew resistance except Pm5 was crossed with the cvs. Florida, Tjelvar, Agra, Olymp and Sabina, all possessing T1BL-1RS and the dominant suppressor SuPm8, with Riebesel 47/51 possessing substitution 1R-1B and SuPm8 and with the T1BL-1RS cvs. Sparta, Iris, Mona without SuPm8. Powdery mildew isolates avirulent on Pm8 and virulent on other Pm genes were used in the trials. Tests for resistance were carried out either on seedlings at the first leaf stage or on detached leaves cultured on benzimidazolagar. No segregation for resistant plants in F₂ of all crosses of the cv. Regina with cultivars possessing T1BL-1RS and SuPm8 indicates that Regina has SuPm8. The segregation ratio 3 resistant: 13 susceptible in the F₂ population of crosses between the cv. Regina and cultivars possessing T1BL-1RS and no SuPm8 also confirms the presence of SuPm8 in the cv. Regina. The obtained results also indicate that expression of Pm2 and Pm4b is not affected by SuPm8 and that SuPm8 does not affect stem rust resistance gene Sr31 located on 1RS segment.

Opis:
In the yeast Saccharomyces cerevisiae three different DNA polymerases α, δ and ε are involved in DNA replication. DNA polymerase α is responsible for initiation of DNA synthesis and polymerases δ and ε are required for elongation of DNA strand during replication. DNA polymerases δ and ε are also involved in DNA repair. In this work we studied the role of these three DNA polymerases in the process of recombinational synthesis. Using thermo-sensitive heteroallelic mutants in genes encoding DNA polymerases we studied their role in the process of induced gene conversion. Mutant strains were treated with mutagens, incubated under permissive or restrictive conditions and the numbers of convertants obtained were compared. A very high difference in the number of convertants between restrictive and permissive conditions was observed for polymerases α and δ, which suggests that these two polymerases play an important role in DNA synthesis during mitotic gene conversion. Marginal dependence of gene conversion on the activity of polymerase ε indicates that this DNA polymerase may be involved in this process but rather as an auxiliary enzyme.

We have analysed the coding capacity of ORFs longer than 100 codons found in the yeast genome. Comparing the parameters describing the DNA asymmetry in the set of known genes and the set of all ORFs>100 codons we have found that there are about 4700 coding ORFs in the yeast genome. Since for more than 2300 ORFs recognisable functions have been already found and for about 2000 ORFs homology to known genes has been identified - only about 400 ORFs can be considered as orphans - ORFs without any known function or homology. This finding means that there is no mystery of orphans - a paradox showing that the fraction of orphans has been growing with the growing number of genes with known functions in the yeast genome.

Opis:
A telomere is a fragment localized at the end of chromosome which protects the chromosome from damage during replication. Telomeres are also factors that control number of cell divisions and are thought to be a suppressors of carcinogenesis since limited, strictly determined number of cell divisions protects from accumulation of mutations in cell. It is assumed that presence of 4-6 mutation in genetic material is a carcinogenic factor and after about 60-70 divisions, the cell enter the resting phase. Telomerase is an enzyme which adds DNA sequence to the 3’ end of DNA and extends the telomere region. This protein is a DNA polymerase dependent on RNA, which syntheses telomere by reverse transcription. The unique characteristics of telomerase is that RNA matrix for DNA synthesis is an integral component of this enzyme. Telomerase is present in intensively dividing cells and its activity is decreasing with age. In normal cells usually activity of telomerase is undetectable but in cancer cells activity of this enzyme is high. The aim of this work is to present the structure of telomeres and the role of proteins involved in maintaining the structure. In details, the structure and function of the telomerase gene/protein is described, including the regulation of gene expression at the transcriptional level. The involvement of telomerase in the neoplastic transformation has been also characterized.
Telomer jest to fragment chromosomu zlokalizowany na jego końcu, który zabezpiecza go przed uszkodzeniem podczas kopiowania. Telomery są także czynnikami kontrolującymi liczbę podziałów komórkowych i dlatego uważane są za supresory transformacji nowotworowej, ponieważ ograniczona, ściśle kontrolowana liczba podziałów zapobiega ewentualnemu kumulowaniu się mutacji w komórce. Przyjęto, że obecność 4-6 mutacji w materiale genetycznym jest czynnikiem karcynogennym, a po granicznej liczbie podziałów (około 60-70) komórka wchodzi w fazę spoczynku M1. Enzymem, którego zadaniem jest dobudowanie 3'-końcowego odcinka nici DNA i tym samym wydłużanie sekwencji telomerowych jest enzym telomeraza. Białko to jest polimerazą DNA zależną od RNA, która syntetyzuje telomery na zasadzie odwrotnej transkrypcji. Unikalną cechą telomerazy jest to, że jej integralnym składnikiem jest matryca RNA służąca do syntezy DNA. Telomeraza występuje w intensywnie dzielących się komórkach, a jej aktywność zmniejsza się wraz z wiekiem. W komórkach prawidłowych zwykle nie stwierdza się aktywności telomerazy, natomiast w nowotworowych aktywność tego enzymu zwykle jest podwyższona. W pracy omówiono strukturę sekwencji telomerowych oraz udział białek zaangażowanych w jej utrzymanie. Szczegółowo przedstawiono także strukturę i funkcję genu/białka telomerazy, z uwzględnieniem regulacji ekspresji genu na poziomie transkrypcji. Scharakteryzowano ponadto udział telomerazy w procesach transformacji nowotworowej.

We investigated the feasibility of a novel therapeutic approach to treat neoplastic diseases in mice. This novel strategy consists in delivering a protein (angiostatin) with strong antiangiogenic properties, followed by administration of the interleukin 12 gene that is strongly immunomodulatory and has also some antiangiogenic effects. When angiostatin-mediated antiangiogenic therapy was used in combination with intratumor delivery of the IL-12 gene (a strategy much safer than IL-12 protein administration), this produced a synergistic therapeutic effect.

This article is primarily concerned with Platoʼs later dialogue, the Sophist, and the reception of the megista-gēnē-dialectic in Neoplatonism (especially Plotinus and Proclus). The present paper offers a historical comparative study that consists of three parts. The first one gives a short summary concerning Platoʼs request regarding the concept of inverse and complex Ideas. The second one examines Plotinus’ conception of the νοῦς (Enn. VI 2, 7–8), in which the megista gēnē στάσις, κίνησις, ὄν, ταὐτόν and ἕτερον constitute the realm of the intellect. While the third and final part of the article investigates Proclusʼ extrapolation of the Platonic dialectic, it focuses on selected passages from the Commentary on the Parmenides. The paper concludes with a summary of the results.

The 150 Y. enterocolitica strains isolated from humans and from pigs belonged to biotypes 4 (68.7%), 1A (18.7%) and 2 (4%), or were biochemically untypeable (8.6%). Biotype 4 was comprised of Y. enterocolitica strains representing serotype 0:3, within biotype 1A the strains either belonged to serotypes 0:5 and 0:6 or were untypeable, and biotype 2 was represented by the strains of serotype 0:9. The strains which were biochemically untypeable belonged to serotypes 0:5, 0:6 and 0:3. Among the strains tested there also were those of an unidentified biotype and serotype. Nearly all the strains of biotype 1A represented genotype ystB+myfA+, and few belonged to genotype ystB+. The presence of the ystB gene in the strains of biotype 1A and only occasional occurrence of the gene in the other biotypes makes ystB a distinguishing marker of biotype 1A. The strains of genotype ystA+ail+myfA+yadA+ predominated in biotype 4 (serotype 0:3). The strains of biotype 2 (serotype 0:9) represented genotype ystA+ail+myfA+, and the plasmid yadA gene was detected in some of them. Within the group of biochemically untypeable strains ystB- and myfA-specific PCR products were mainly obtained. The genotypes determined for the tested biotypes and serotypes of Y. enterocolitica, based upon the selected genes of virulence, can be applied as distinguishing markers and indicators of the potential virulence of Y. enterocolitica strains, excluding bioserotyping.

Opis:
The family Gobiidae is the largest teleost family, consisting of more than 2,000 species in more than 200 genera. They have adapted to a wide range of habitats, inhabiting mostly marine and brackish waters. Recently invasive Ponto-Caspian gobies have caused significant changes to the structure of fish assemblage throughout the European waters. The aim of the study was to verify the possibility of identifying three species of the genus Gobiidae based on the analysis of the mitochondrial region of the cytochrome oxidase subunit 1 (COI) gene. 339 samples originated from seven countries and 17 different sites were investigated. Qualitative and quantitative assessment of the extracted DNA was conducted by measuring light absorbance and electrophoretic separation. Approximately 650-bp (base pairs) fragments were amplified from the 5' region of the mitochondrial COI with the PCR (polymerase chain reaction) reaction. Sequences of 652 bp were obtained and compared with reference sequences in the National Center for Biotechnology Information (NCBI). Based on the sequence analysis, we determined that in the analysed geographical regions, the goby preliminary identified morphologically as the round goby was represented by three species: round goby (Neogobius melanostomus), tubenose goby (Proterorhinus marmoratus), and monkey goby (Neogobius fluviatilis). The latter two are newly reported for their new habitats. Genetic characterisation of such populations offers the opportunity to assess their genetic stability, which provides agencies managing the aquatic environment in EU countries with a tool for revising the legislation, including regulations relevant for updating the status of native and invasive species in European waters.

PCR-RFLP with AluI endonuclease of the gap gene as well as nuc (450 bp) and coa (1130 bp) gene amplification allowed precise S. aureus species identification. One hundred percent of the genetic relationship between strains was established via RAPD-PCR and coa-typing.

Canine mammary sarcomas are usually very aggressive and easily metastasize. Unfortunately the biology of this type of tumor is not well known because they are a very rare type of tumors. The aim of this study was to find differences in gene expression patterns in canine mammary osteosarcomas (malignant) versus osteomas (benign) using DNA microarrays. Our microarray experiment showed that 11 genes were up-regulated in osteosarcoma in comparison to osteoma whereas 36 genes were down-regulated. Among the up-regulated genes were: PDK1, EXT1, and EIF4H which are involved in AKT/PI3K and GLI/Hedgehog pathways. These genes play an important role in cell biology (cancer cell proliferation) and may be essential in osteosarcoma formation and development. Analyzing the down-regulated genes, the most interesting seemed to be HSPB8 and SEPP1. HSPB8 is a small heat shock protein that plays an important role in cell cycle regulation, apoptosis, and breast carcinogenesis. Also SEPP1 may play a role in carcinogenesis, as its down-regulation may induce oxidative stress possibly resulting in carcinogenesis. The preliminary results of the present study indicate that the up-regulation of three genes EXT1, EIF4H, and PDK1 may play an essential role in osteosarcoma formation, development and proliferation. In our opinion the cross-talk between GLI/Hedgehog and PI3K/AKT pathways may be a key factor to increase tumor proliferation and malignancy.

Opis:
The antigen content of plasminogen activator inhibitor-1 (PAI-1) in primary breast cancer tissue extracts may be of strong prognostic value: high levels of PAI-1 in tumors predict poor prognosis for patients. The gene encoding PAI-1 is highly polymorphic and an insertion (5G)/deletion (4G) polymorphism in the PAI-1 gene promoter (the 4G/5G polymorphism), may have functional significance in PAI-1 expression. In the present work the distribution of genotypes and frequency of alleles of the 4G/5G polymorphism in subjects with breast cancer were investigated. Tumor tissues were obtained from 100 postmenopausal women with node-negative and node-positive ductal breast carcinoma with uniform tumor size. Blood samples from age matched healthy women served as control. The 4G/5G polymorphism was determined by PCR amplification using the allele specific primers. The distribution of the genotypes of the 4G/5G polymorphism in both control and patients did not differ significantly (P > 0.05) from those predicted by the Hardy-Weinberg distribution. There were no differences in the genotype distributions and allele frequencies between node-positive and node-negative patients. The 4G/5G polymorphism may not be linked with elevated level of PAI-1 observed in breast cancer and therefore may not be associated with appearance and/or progression of breast cancer.

Opis:
The aim of this study was to estimate the relations between the CRH-A145G polymorphism and milk production traits (yields of milk, protein, and fat, as well as protein and fat content) in 176 Jersey cows. The genotype and allele frequencies were estimated and they were as follows: AG – 0.31; GG – 0.69; A – 0.16; G – 0.84. Statistical analysis revealed that studied polymorphism significantly affected the fat yield, fat content (P≤0.05) and protein content in milk (P≤0.05). The results indicate that selection for the CRH-A145G AG animals might contribute to increase the value of these traits in Jersey cattle. However, further studies are necessary to verify the results of our study.
Celem badań było oszacowanie zależności między polimorfizmem CRH-A145G a cechami użytkowości mlecznej (wydajnością mleka, tłuszczu i białka oraz zawartością tłuszczu i białka w mleku) bydła. Badania przeprowadzono na stadzie 176 krów rasy jersey. Oszacowano częstość występowania genotypów i alleli, które wynosiły: AA – 0,00; AG – 0,31; GG – 0,69; A – 0,16; G – 0,84.Analiza statystyczna wykazała, że badany polimorfizm wpływał istotnie na wydajność tłuszczu i zawartość tłuszczu (P≤0,01) oraz na zawartość białka w mleku (P≤0,05).Wyniki wskazują, że uwzględnienie w selekcji osobników z genotypem CRH-A145G AG mogłoby przyczynić się do zwiększenia wartości powyższych cech u bydła rasy jersey. Wymagane jest jednak kontynuowanie badań aby móc zweryfikować uzyskane wyniki.

Opis:
Barley doubled haploids (DH) derived from first and second cycle hybrids were investigated in field experiments. Parental lines designed for the second cycle hybrids were three doubled haploids from the first cycle hybrids, which were observed to have the highest grain yield. Yield structure characters, crude protein content and protein fractions were analysed. Phenotypic and genetic variability and the frequency of transgression in the studied populations were calculated. For the studied traits additive, [d], and epistatic (additive x additive), [i], effects as well as coefficient of gene dispersion were estimated. It was found that the phenotypic and genetic variability of DH populations derived from second cycle hybrids was higher than that of the original population for all the studied traits except grain yield. A greater proportion of transgressive lines than in the original population was also observed in populations from second cycle hybrids. Only one DH line exceeding the high yielding parent was found among 141 lines under study. The relationship between the frequency of transgressions and gene dispersion was recorded: the greatest number of transgressive lines occurred in those traits for which the dispersion was observed.

Aldose reductase gene polymorphisms has been indicated to be associated with diabetic retinopathy (DR). The research data were from PubMed and EMBASE. We identified -106C > T single nucleotide polymorphism (SNP). Pool odds ratio (OR) with 95% CI were calculated. Nine studies were included. ALR2 106C > T gene polymorphisms was associated with the increased risk of DR in T1DM (C vs. T, OR = 2.07, p = 0.001; CC vs. CT + TT, OR = 2.56, p = 0.005). T allele and TT genotype were associated with decreased risk of DR in T1DM (OR = 0.48, p = 0.0001 and OR = 0.12, p = 0.0005). In conclusion, C allele and CC genotype may be a risk factor, while T allele and TT genotype may serve as protective factor for DR in T1DM patient.

Opis:
Gene therapy and genetic vaccines promise to revolutionize the treatment of inherited and acquired diseases. Since viral vectors are generally associated with numerous disadvantages when applied to humans, the administration of naked DNA, or DNA packed into lipo- or polyplexes emerge as viable alternatives. To satisfy the increasing demand for pharmaceutical grade plasmids we developed a novel economic downstream process which overcomes the bottlenecks of common lab-scale techniques and meets all regulatory requirements. After cell lysis by an in-house developed gentle, automated continuous system the sequence of hydrophobic interaction, anion exchange and size exclusion chromatography guarantees the separation of impurities as well as undesired plasmid isoforms. After the consecutive chromatography steps, adjustment of concentration and final filtration are carried out. The final process was proven to be generally applicable and can be used from early clinical phases to market-supply. It is scaleable and free of animal-derived substances, detergents (except lysis) and organic solvents. The process delivers high-purity plasmid DNA of homogeneities up to 98% supercoiled form at a high yield in any desired final buffer.

Opis:
The myelin protein zero gene (MPZ) coding for the most abundant protein of the peripheral myelin was shown to be mutated in Charcot-Marie-Tooth type 1B disease (CMT1B). Later on MPZ mutations have been shown in axonal type of CMT (CMT2). Recently three novel MPZ gene mutations were reported in congenital hypomyelinating neuropathy (CHN). In contrast to the previously reported studies, focused on CMT1B disease, we aimed to analyze the coding and promoter sequences of the MPZ gene in a group of patients with three CMT phenotypes i.e.: CMT1, CMT2 and CHN. Over 500 PCR products were screened by single strand conformation polymorphism analysis (SSCP) and heteroduplex analysis (HA). In one CMT2 family we founded the E56K mutation in the MPZ gene and in one CHN patient the T124K substitution was detected. In agreement with previously reported studies we conclude that MPZ gene screening should be performed for wide phenotype spectrum of CMT.

Opis:
Cryptographic hash functions are fundamental primitives in modern cryptography and have many security applications (data integrity checking, cryptographic protocols, digital signatures, pseudo random number generators etc.). At the same time novel hash functions are designed (for instance in the framework of the SHA-3 contest organized by the National Institute of Standards and Technology (NIST)), the cryptanalysts exhibit a set of statistical metrics (propagation criterion, frequency analysis etc.) able to assert the quality of new proposals. Also, rules to design "good" hash functions are now known and are followed in every reasonable proposal of a new hash scheme. This article investigates the ways to build on this experiment and those metrics to generate automatically compression functions by means of Evolutionary Algorithms (EAs). Such functions are at the heart of the construction of iterative hash schemes and it is therefore crucial for them to hold good properties. Actually, the idea to use nature-inspired heuristics for the design of such cryptographic primitives is not new: this approach has been successfully applied in several previous works, typically using the Genetic Programming (GP) heuristic [1]. Here, we exploit a hybrid meta-heuristic for the evolutionary process called Gene Expression Programming (GEP) [2] that appeared far more efficient computationally speaking compared to the GP paradigm used in the previous papers. In this context, the GEPHashSearch framework is presented. As it is still a work in progress, this article focuses on the design aspects of this framework (individuals definitions, fitness objectives etc.) rather than on complete implementation details and validation results. Note that we propose to tackle the generation of compression functions as a multi-objective optimization problem in order to identify the Pareto front i.e. the set of non-dominated functions over the four fitness criteria considered. If this goal is not yet reached, the first experimental results in a mono-objective context are promising and open the perspective of fruitful contributions to the cryptographic community.

The bovine kappa-casein (CASK) gene is known as a potential quantitative trait locus in dairy cattle breeding. However, the molecular basis of the effect of the CASK allele B on different milk properties remains unclear. In this report, a 214 bp fragment of the 5' untranslated region of the CASK gene containing 5 potential consensus sequenses for different transcription factors was PCR-amplified to find RFLPs. A Dde I RFLP was identified. In a population of 112 Bos taurus (86 cows and 26 bulls of Polish Black and White crossbred Holstein-Friesian) and 7 Bison bonasus individuals, 7 had no recognition sites for Dde I, 23 were heterozygous and 89 were cut completely into two fragments.

Jako matematycy pragniemy udowadniać twierdzenia i wyprowadzać analityczne wzory. Bardzo szybko okazuje się, że w istotnych zastosowaniach jest to niemożliwe. Co robić? Część z nas ucieka w wyrafinowane symulacje komputerowe. Czy nie ma innej drogi? Czy jesteśmy ograniczeni do wyboru pomiędzy Matematyką i Mathematicą? Na pomoc przychodzi metoda samouzgodnionego pola średniego. Ferromagnetyczny model Isinga i samoregulujący się gen zilustrują nam tę niezwykle uniwersalną metodę otrzymywania przybliżonych rozwiązań analitycznych.
Many processes in natural and social sciences can be modeled by systems of interacting objects. It is usually very difficult to obtain analytic expressions describing time evolution and equilibrium behavior of such systems. Very often we rely only on computer simulations. Fortunately, in many cases one can construct useful approximation schemes and derive exact results which capture some specific features of a given process. A frequent approach is to replace interactions between objects by a mean interaction. Here we illustrate a self-consistent mean-field approximation in two examples: the Ising model of interacting spins and a simple model of a self-regulating gene.

Opis:
A small number (1-5%) of Alzheimer's disease (AD) cases associated with the early-onset form of the disease (EOAD) appears to be transmitted as a pure genetic, autosomal dominant trait. To date, three genes responsible for familial EOAD have been identified in the human genome: amyloid precursor protein (APP), presenilin 1 (PS1), and presenilin 2 (PS2). Mutations in these genes account for a significant fraction (18 to 50%) of familial cases of early onset AD. The mutations affect APP processing causing increased production of the toxic Aβ42 peptide. According to the "amyloid cascade hypothesis", aggregation of the Aβ42 peptide in brain is a primary event in AD pathogenesis. In our study of twenty AD patients with a positive family history of dementia, 15% (3 of 20) of the cases could be explained by coding sequence mutations in the PS1 gene. Although a frequency of PS1 mutations is less than 2% in the whole population of AD patients, their detection has a significant diagnostic value for both genetic counseling and treatment in families with AD.

Opis:
Gene pool variation of twenty varieties and breeding clones of Fragaria × ananassa, nine varieties and breeding lines of Fragaria vesca, and one new interspecific hybrid designated Fragaria × anavesca was analysed with three DNA marker systems. ISSR reactions with four primers produced 45 polymorphic markers. Similarly, RAPD analyses with three primers produced 26 markers and SSR method with three primer pairs revealed 28 different alleles. The total number of 99 polymorphic markers allowed distinguishing clearly a group of F. × ananassa genotypes from that of F. vesca genotypes with F. × anavesca in between of these two. RAPD markers proved to be more informative than ISSRs as 3 of 26 were specific to F. × ananassa only and one exclusively to F. vesca and F. × anavesca. Thus, the presumed hybrid nature of F. × anavesca was effectively confirmed by RAPD markers. Especially important was the 1100bp long PCR product of the B104 primer present in all F. vesca genotypes as well as in F. × anavesca but absent in F. × ananassa. Presence of F. vesca DNA in the hybrid F. × anavesca was additionally corroborated by the 223bp product of the UDF017 primer pair and the 185bp-long band generated with the UDF006 primer pair.
Analizowano zmienność w puli genów dwudziestu odmian i klonów hodowlanych Fragaria × ananassa, dziewięciu odmian i linii hodowlanych Fragaria vesca i nowego prawdopodobnego mieszańca międzygatunkowego nazwanego Fragaria × anavesca przy zastosowaniu trzech systemów markerów DNA. Cztery startery ISSR wygenerowały 45 markerów polimorficznych. Trzy startery RAPD dały 26 markerów, natomiast trzy startery SSR – 28 markerów polimorficznych. 99 uzyskanych markerów polimorficznych pozwoliło na jednoznaczne odróżnienie grupy genotypów należących do gatunku F. × ananassa od grupy genotypów należących do gatunku F. vesca z mieszańcem F. × anavesca sytuującym się pomiędzy nimi. Markery RAPD okazały się lepszym źródłem informacji niż ISSR, ponieważ 3 spośród 26 były specyficzne tylko dla F. × ananassa, a jeden wyłącznie dla F. vesca i F. × anavesca. W ten sposób, za pomocą markerów RAPD, potwierdzona została przypuszczalna wcześniej mieszańcowość F. × anavesca. Szczególnie istotny okazał się produkt reakcji PCR ze starterem B104 o długości 1100pz obecny we wszystkich genotypach F. vesca oraz F. × anavesca, a niewystępujący u F. × ananassa. Obecność DNA pochodzącego z F. vesca w mieszańcu F. × anavesca została dodatkowo potwierdzona poprzez produkt pary starterów UDF017 o długości 223pz i produkt pary starterów UDF006 o długości 185pz.

Opis:
Angiotensin I-converting enzyme (ACE), which plays an important role in blood pressure regulation, and methylenetetrahydrofolate reductase (MTHFR) involved in homocysteine metabolism belong to a large group of polypeptides which may be potential risk factors for atherosclerosis and coronary artery disease (CAD). To assess whether polymorphisms of the genes encoding these peptides are associated with CAD in Silesian we conducted a study among 68 individuals suffering from CAD (including 52 cases after myocardial infarction), 51 subjects with positive family history of CAD and 111 controls. We analysed the distribution of genotypes and allele frequencies of the insertion/deletion (I/D) polymorphism in the ACE gene using PCR amplification, and the C677→T polymorphism in the MTHFR gene using PCR-RFLP analysis. We found that D allele frequency was significantly higher in CAD patients (61%) than in controls (43%) (P = 0.001, OR = 2.06). The D allele carriers (DD + ID genotypes) were more frequent in the CAD patients (85%) compared to control group (65%) (P = 0.003, OR = 3.14), whereas the familial CAD risk group shows the highest frequency of the ID genotype (57% vs 43% in controls). In contrast, the MTHFR polymorphism does not seem to be associated with the disease. Our data indicate that in Silesian CAD patients the disease is strongly associated with carrier-state of the ACE D allele, but not with the C677→T transition in the MTHFR gene.

Previous studies in other countries have shown that single nucleotide polymorphisms (SNPs) in the growth arrest-specific gene 6 (Gas6; rs8191974) and adapter-related protein complex 3 subunit sigma-2 (Ap3s2; rs2028299) were associated with an increasedrisk for type 2 diabetes mellitus (T2DM). However, the association of these loci with T2DM has not been examined in Chinese populations. We performed a replication study to investigate the association of these susceptibility loci with T2DM in the Chinese population.We genotyped 1968 Chinese participants (996 with T2DM and 972controls) for rs8191974 in Gas6 and rs2028299 near Ap3s2, and examined their association with T2DM using a logistic regression analysis. We also analyzed the correlation of genotypes and clinical phenotypes. The distribution of the T allele of SNP rs8191974 in the Gas6 gene was significantly different between T2DM cases and controls when compared with the C allele (P<0.05, OR: 0.80, 95% CI: 0.69-0.94). The occurrence of the CT genotype and the dominant model was also significantly less frequent in the T2DM cases vs. controls when compared with the CC genotype (CT vs. CC: P<0.05, OR: 0.75, 95% CI:0.62-0.90; TT+CT vs. CC: P<0.05, OR:0.75, 95% CI:0.63-0.90). In SNP rs2028299, the allele C showed no statistically significant differencein distribution between the control and T2DM groups when compared with allele A. However, in male populations, the dominant model was statistically more frequent when compared with genotype AA (CC+CA vs. AA: P<0.05, OR:1.29, 95% CI:1.02-1.64), and in obesity-stratified analysis, we also observed a significant difference in the distribution of the dominant model between the T2DM cases and controls in subjects with BMI≥24 kg/m2 and BMI<28kg/m2 (CC+CA vs. AA: P<0.05, OR: 6.33, 95% CI:4.17-9.61). In conclusion, our study shows that SNPsrs8191974 and rs2028299 are significantly associated with T2DM in the Chinese population.

Opis:
In this paper we present a method for evaluating the importance of GO terms which compose multi-attribute rules. The rules are generated for the purpose of biological interpretation of gene groups. Each multi-attribute rule is a combination of GO terms and, based on relationships among them, one can obtain a functional description of gene groups. We present a method which allows evaluating the influence of a given GO term on the quality of a rule and the quality of a whole set of rules. For each GO term, we compute how big its influence on the quality of generated set of rules and therefore the quality of the obtained description is. Based on the computed quality of GO terms, we propose a new algorithm of rule induction in order to obtain a more synthetic and more accurate description of gene groups than the description obtained by initially determined rules. The obtained GO terms ranking and newly obtained rules provide additional information about the biological function of genes that compose the analyzed group of genes.

In this work I present some preliminary results of the exploration of the interplay between stochastic gene switching and certain metronomics therapies. During the research a simple model of gene-mRNA-protein network subjected to the metronomic therapy was investigated. The results show that the stochastic gene switching process, especially the time expected between successive switching plays a significant role in determining the size of the responding cells fraction.

Opis:
Relatively successful elsewhere, gene delivery aimed at the vasculature and kidney has made very little progress. In the kidney, the hurdles are related to the unique structure–function relationships of this organ and in the blood vessels to a variety of, mostly endothelial, factors making the delivery of transgenes very difficult. Among gene-therapeutic approaches, most viral gene delivery systems utilized to date have shown significant practical and safety-related limitations due to the level and duration of recombinant transgene expression as well as their induction of a significant host immune response to vector proteins. Recombinant adeno-associated virus (rAAV) vectors appear to offer a vehicle for safe, long-term transgene expression. rAAV-based vectors are characterized by a relative non-immunogenicity and the absence of viral coding sequences. Furthermore, they allow for establishment of long-term latency without deleterious effects on the host cell. This brief review addresses problems related to transgene-delivery to kidney and vasculature with particular attention given to rAAV vectors. The potential for gene therapy as a strategy for selected renal and vascular diseases is also discussed.

Opis:
Angiogenesis, i.e. formation of new blood vessels out of pre-existing capillaries, is essential to the development of tumour vasculature. The discovery of specific antiangiogenic inhibitors has important therapeutic implications for the development of novel cancer treatments. Vasostatin, the N-terminal domain of calreticulin, is a potent endogenous inhibitor of angiogenesis and tumour growth. In our study, using B16(F10) murine melanoma model and electroporation we attempted intramuscular transfer of human vasostatin gene. The gene therapy was combined with antiangiogenic drug dosing schedule of a known chemotherapeutic (cyclophosphamide). The combination of vasostatin gene therapy and cyclophosphamide administration improved therapeutic effects in melanoma tumours. We observed both significant inhibition of tumour growth and extended survival of treated mice. To our knowledge, this is one of the first reports showing antitumour efficacy of electroporation-mediated vasostatin gene therapy combined with antiangiogenic chemotherapy.

Opis:
Peroxisome proliferator-activated receptor α (PPARα) is a transcription factor that regulates lipid and glucose metabolism. Accumulating evidence suggests that the intron 7 C allele of the PPARA gene rs4253778 G/C polymorphism has an advantage for power-oriented athletes, presumably due to the hypertrophic effects on skeletal muscle and increase in glucose utilization in response to anaerobic exercise. The G allele, however, is said to be favorable for the endurance-oriented athletes. The metabolic demands of team sports involve aerobic and anaerobic energy pathways, as a result of the intermittent physical activity. The aim of the present study was to investigate the association between the PPARA gene polymorphism and team-sport athletic status. A total of 665 Russian athletes from 14 team sports and 1,706 controls were involved in the case-control study. We found that the frequency of the PPARA C allele was significantly higher in athletes compared to controls (20.5 vs. 16.4%, P = 0.0009), suggesting that anaerobic rather than aerobic metabolism may be crucial to the game performance in team sports. This means that our study indicates the association between the PPARA gene G/C polymorphism and team-sport athletic status. Although more replication studies are needed, the preliminary data suggest an opportunity to use the analysis of PPARA polymorphism, along with other gene variations and standard phenotypic assessment in team sports selection.

Opis:
Several years ago it was discovered that plant transformation with a transcribed sense transgene could shut down the expression of a homologous endogenous gene. Moreover, it was shown that the introduction into the cell of dsRNA (double-stranded RNA) containing nucleotide sequence complementary to an mRNA sequence causes selective degradation of the latter and thus silencing of a specific gene. This phenomenon, called RNA interference (RNAi) was demonstrated to be present in almost all eukaryotic organisms. RNAi is also capable of silencing transposons in germ line cells and fighting RNA virus infection. Enzymes involved in this process exhibit high homology across species. Some of these enzymes are involved in other cellular processes, for instance developmental timing, suggesting strong interconnections between RNAi and other metabolic pathways. RNAi is probably an ancient mechanism that evolved to protect eukaryotic cells against invasive forms of nucleic acids.

Opis:
Calcyclin (S100A6) is believed to participate in cell cycle control. It was, however, unclear if its expression depends on p53, a key regulator of apoptosis and cell cycle. We therefore performed transcription regulation assays in HeLa cells and found that wild type p53 suppressed the S100A6 promoter up to 12-fold in a dose-dependent manner. In contrast, the well-characterized V143A, R175H, R249S, and L344A p53 mutants cloned from human cancers suppressed this promoter with a 6 to 9-fold lower efficiency. All the sites mediating the p53-dependent suppression were contained in the -167 to +134 fragment of the S100A6 promoter. Separate overexpression of either Sp1 or of NFκB only partially counteracted the p53 inhibitory effect on the S100A6 promoter, while simultaneous overexpression of both these transactivators resulted in a complete abolishment of the p53 inhibitory effect on this promoter. Sp1 and NFκB binding to the probes resembling their putative binding sites present in the S100A6 promoter was decreased in the presence of wild type p53. We propose that the suppression of S100A6 is yet another mechanism by which p53 inhibits proliferation. Insufficient suppression of this gene by p53 mutants could well be responsible for calcyclin overexpression and cell cycle deregulation observed in cancer tissues.

Opis:
The transmission of previously described genes A2MD1 and A2ME2 that determine antigenic markers of alpha₂-macroglobulins A₂mD1 and А₂mЕ2 in cattle was studied. The starting point for the analyses was the lack of individuals negative for both markers in the population of 3551 Black-and-White, Red-and-White, Polish Red and Simmental cattle and interbreed crosses. Controlling of these specificities by allelic genes or genes from closely linked loci was considered. To support or reject this hypothesis, the independence test 2 x 2 and analysis of segregation of A₂mD1 and А₂mЕ2 in the offsprings of all phenotypic matings found and of selected matings in which genotypes of sires were determined, were used. It was found that the observed segregation of antigenic markers in the offsprings rules out the possibility that they are determined by allelic genes. The results obtained show that markers A₂mD1 and А₂mЕ2 are controlled by the genes A2MD1 and A2ME2 from closely linked loci. Moreover it seems that only those haplotypes are transmitted in which both genes - A2MD1 and A2ME2, or one of them - A2MD1 or A2ME2, are present. No haplotypc would then be transmitted (would occur?) in which both genes are in the recessive form. recessive form.

Opis:
Despite the extensive research efforts over the past 25 years that have focused on HIV, there is still no cure for AIDS. However, tremendous progress in the understanding of the structure and biology of the HIV virus led to the development of safe and potent HIV-based transgene delivery vectors. These genetic vehicles are referred to as lentiviral vectors. They appear to be better suited for particular applications, such as transgene delivery into stem cells, compared to other viral- and non-viral vectors. This is because Lentivirus-based vectors can efficiently infect nondividing and slowly dividing cells. In the present review article, the current state of understanding of HIV-1 is discussed and the main characteristics that had an impact on vector design are outlined. A historical view on the vector concept is presented to facilitate discussion of recent results in vector engineering in a broader context. Subsequently, a state of the art overview concerning vector construction and vector production is given. This review also touches upon the subject of lentiviral vector safety and related topics that can be helpful in addressing this issue are discussed. Finally, examples of Lentivirus-based gene delivery systems and their applications are presented, with emphasis on animal transgenesis and human gene therapy.

Opis:
Introduction: According to the World Health Organization, depression is the most common mental disorder. Over 350 million people suffer from this disease, making it the fourth most important health problem in the world. Multidrug resistance protein 1 (MRP1), encoded by ABCC1 gene is co–creating the blood– brain barrier and blood–cerebrospinal fluid barrier. Changes in the expression of ABCC1 can influence the bioavailability of antidepressants, and thereby, determine the efficacy of the treatment. The aim of the study was to evaluate ABCC1 gene expression in patients with depression. Material and methods: We analyzed 32 samples of RNA isolated from the leukocytes of peripheral blood, derived from Babinski Hospital patients suffering from recurrent depressive episodes. The investigated gene expression was assessed using the technique of Real–time PCR. Results: On the basis of qualitative analysis, ABCC1 gene expression has been shown in 30 samples, and the GAPDH gene expression in 32 samples. All 32 samples were quantitatively analyzed. The level of ABCC1 gene expression relative to GAPDH gene was variable among all 32 cases. An average, positive and significant correlation (r = 0.3988) between age of the patients and the relative expression level of ABCC1 has been shown. Conclusions: The relative level of gene expression increases with the age of the patients with depression. The obtained results require confirmation in a larger group of patients.
Wstęp: Według Światowej Organizacji Zdrowia depresja jest najczęściej występującym zaburzeniem psychicznym. Ponad 350 milionów ludzi na całym świecie cierpi na tę chorobę, co czyni ją czwartym z najważniejszych obecnie problemów zdrowotnych. Białko oporności wielolekowej 1 (MRP1), kodowane przez gen ABCC1, jest elementem współtworzącym barierę krew–mózg oraz krew–płyn mózgowo–rdzeniowy. Zmiana ekspresji genu ABCC1 może wpłynąć na biodostępność leków antydepresyjnych, a tym samym na skuteczność farmakoterapii. Celem pracy była ocena ekspresji genu ABCC1 u pacjentów chorych na depresję. Materiał i metody: Badaniu poddano 32 próby RNA wyizolowane z leukocytów krwi obwodowej pacjentów chorych na depresję, leczonych w szpitalu im. Babińskiego w Łodzi. Ekspresja badanego genu została oceniona przy użyciu techniki Real–time PCR. Wyniki: Na podstawie analizy jakościowej wykazano ekspresję genu ABCC1 w 30 próbach, a genu referencyjnego GAPDH w 32 próbach. Wszystkie 32 próby poddano analizie ilościowej. Poziom ekspresji genu ABCC1 względem genu GAPDH we wszystkich 32 przypadkach był wysoce zróżnicowany. Wykazano przeciętną, dodatnią, istotną statystycznie korelację (r = 0,398 pomiędzy wiekiem pacjentów, a względnym poziom ekspresji genu ABCC1. Wnioski: Względny poziom ekspresji genu ABCC1 jest tym wyższy, im wyższy jest wiek pacjentów w grupie badanej. Uzyskane w pracy wyniki badań wymagają potwierdzenia na większej grupie pacjentów.

Opis:
A lipase gene SR1 encoding an extracellular lipase was isolated from oil-contaminated soil and expressed in Escherichia coli. The gene contained a 1845-bp reading frame and encoded a 615-amino-acid lipase protein. The mature part of the lipase was expressed with an N-terminal histidine tag in E. coli BL21, purified and characterized biochemically. The results showed that the purified lipase combines the properties of Pseudomonas chlororaphis and other Serratia lipases characterized so far. Its optimum pH and temperature for hydrolysis activity was pH 5.5-8.0 and 37°C respectively. The enzyme showed high preference for short chain substrates (556.3±2.8 U/µg for C10 fatty acid oil) and surprisingly it also displayed high activity for long-chain fatty acid. The deduced lipase SR1 protein is probably from Serratia, and is organized as a prepro-protein and belongs to the GXSXG lipase family.

Opis:
This report describes gene transfer in vitro as well as in vivo using cetylated low-molecular mass (600 Da) polyethylenimine (28% of amine groups substituted with cetyl moieties), termed CT-PEI. This compound is hydrophobic and has to be incorporated into liposomes in order to be suitable for gene transfer studies. Serum-induced plasmid DNA degradation assay demonstrated that CT-PEI-containing liposomal carriers could protect complexed DNA (probably via condensation). In vitro luciferase gene expression achieved using medium supplemented with 10% serum was comparable to that achieved in serum-reduced medium and was highest for CT-PEI/cholesterol liposomes, followed by CT-PEI/dioleoylphosphatidylcholine liposomes and PEI 600 Da (uncetylated) carrier. In vivo systemic transfer into mice was most efficient when liposome formulations contained CT-PEI and cholesterol. Higher luciferase expression was then observed in lungs than in liver. In conclusion: liposomes containing cetylated polyethylenimine and cholesterol are a suitable vehicle for investigating systemic plasmid DNA transfer into lungs.

Opis:
Background: Folate metabolism dysfunctions can result in DNA hypomethylation and abnormal chromosome segregation. Two common polymorphisms of the methylenetetrahydrofolate reductase (MTHFR) encoding gene (C677T and A1298C) reduce MTHFR activity, but when associated with aneuploidy, the results are conflicting. Turner Syndrome (TS) is an interesting model for investigating the association between MTHFR gene polymorphisms and nondisjunction because of the high frequency of chromosomal mosaicism in this syndrome. Objective: To investigate the association of MTHFR gene C677T and A1298C polymorphisms in TS patients and their mothers and to correlate these polymorphisms with maternal risk of TS offspring. Subjects and Methods: MTHFR C677T and A1298C polymorphisms were genotyped in 33 TS patients, their mothers and 15 healthy females with their mothers as controls using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing technique. Results: Genotype and allele frequencies of both C677T and A1298C were not significantly different between TS cases and controls. There were no significant differences in C677T genotype distribution between the TS mothers and controls (p=1). The MTHFR 1298AA and 1298AC genotypes were significantly increased in TS mothers Vs. control mothers (p=0.002). The C allele frequency of the A1298C polymorphism was significantly different between the TS mothers and controls (p=0.02). The association of A1298C gene polymorphism in TS patients was found to increase with increasing age of both mothers (p=0.026) and fathers (p=0.044) of TS cases. Conclusion: Our findings suggest a strong association between maternal MTHFR A1298C and risk of TS in Egypt.

Opis:
For determination of the relationships among significant gene markers, statistical analysis and association rule mining are considered as very useful protocols. The first protocol identifies the significant differentially expressed/methylated gene markers, whereas the second one produces the interesting relationships among them across different types of samples or conditions. In this article, statistical tests and association rule mining based approaches have been used on gene expression and DNA methylation datasets for the prediction of different classes of samples (viz., Uterine Leiomyoma/class-formersmoker and uterine myometrium/class-neversmoker). A novel rule-based classifier is proposed for this purpose. Depending on sixteen different rule-interestingness measures, we have utilized a Genetic Algorithm based rank aggregation technique on the association rules which are generated from the training set of data by Apriori association rule mining algorithm. After determining the ranks of the rules, we have conducted a majority voting technique on each test point to estimate its class-label through weighted-sum method. We have run this classifier on the combined dataset using 4-fold cross-validations, and thereafter a comparative performance analysis has been made with other popular rulebased classifiers. Finally, the status of some important gene markers has been identified through the frequency analysis in the evolved rules for the two class-labels individually to formulate the interesting associations among them.

Opis:
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important foliar diseases of cereals. Infection by this pathogen on triticale has intensified in Poland in the last few years. In this study we examined resistance to powdery mildew in triticale hybrids possessing resistance genes Pm4b and Pm6 introduced from common wheat. The materials tested were hybrids derived from triticale crosses with common wheat cultivars carrying the desired resistance genes. The presence of the transferred genes was reflected in increased field resistance and shown by the use of molecular markers. The paper discusses the potential introduction of the genes to improve powdery mildew resistance.

Opis:
This is an application paper of applying standard methods of computational intelligence to identify diagnostic gene targets and to use them for a successful diagnosis of a medical problem - acute graft-versus-host disease (aGVHD). This is the major complication after allogeneic haematopoietic stem cell transplantation (HSCT) in which functional immune cells of donor, recognize the recipient as ”foreign” and mount an immunologic attack. In this paper we analyzed gene-expression profiles of 47 genes associated with allo-reactivity in 59 patients submitted to HSCT. We have applied different dimensionality reduction techniques of the variable space, combined with different classifiers to detect the aGVHD at onset of clinical signs. This is a preliminary study which utilises both computational and biological evidence for the involvement of a limited number of genes for the diagnosis of aGVHD. Directions for further studies are also outlined in this paper.

Opis:
A large population of anther culture-derived barley regenerants and their progeny was tested for allele segregation at 1 isozyme and 8 morphological marker loci. The segregation of genetic markers was examined separately for haploid, diploid and polyploid regenerants. All the 9 analysed genes except al (albino lemma) on chromosome 3 segregated according to the expected 1:1 ratio in the microspore-derived barley population. There was no difference in allele distribution between haploid and diploid regenerants. Among the limited number of 34 analysed tetraploids a significant excess of the dominant allele at locus о (orange lemma) of chromosome 6 was also observed. The recombination frequency between linked genes (n - lk2 on chromosome 1 and r - s on chromosome 7) estimated in the DH population did not differ significantly from recombination rates calculated in F₂ progeny or presented in barley chromosome maps. The phenomenon of gametic selection is discussed in relation to the genotype dependency of anther culture response and procedures used for DH production in barley.

Opis:
Obesity is a growing problem worldwide. The risk of the excessive body weight occurrence is a multifactorial issue. Environmental factors, lifestyle habits, diet, physical activity level, as well as genetic predisposition can increase obesity risk. One of the genes studied – the FTO gene - plays a crucial role in obesity occurrence. Individuals who carry risk alleles of specific single nucleotide polymorphisms (SNP) have a greater risk of being overweight. Recent studies revealed that specific macronutrient diet composition can influence differently on the FTO expression. The aim of this article is to review the recent literature on the topic of the FTO gene, its influence on overweight and obesity prevalence and the role of diet in modifying its impact on the risk of the excessive body weight occurrence. There are not many studies focusing on the dietary intervention influence on the FTO gene expression. As far as it has been researched it seems that the proper dietary habits can modify the FTO gene risk allele influence on obesity susceptibility.
Otyłość jest rosnącym problemem na całym świecie. Ryzyko występowania nadmiernej masy ciała stanowi problem wieloczynnikowy. Czynniki środowiskowe, styl życia, dieta, poziom aktywności fizycznej, a także predyspozycje genetyczne mogą zwiększać ryzyko otyłości. Jeden z badanych genów - gen FTO - odgrywa kluczową rolę w występowaniu otyłości. Osoby, które są nosicielami alleli ryzyka specyficznych polimorfizmów pojedynczych nukleotydów (ang. SNP - Single Nucleotide Polymorphism) tego genu charakteryzują się większym ryzykiem wystąpienia nadwagi. Najnowsze badania wykazały, że specyficzny udział makroskładników diety może wpływać w różny sposób na ekspresję FTO. Celem niniejszego artykułu jest przegląd najnowszej literatury na temat genu FTO, jego wpływ na częstość występowania nadwagi i otyłości oraz roli diety w modyfikacji jego wpływu na ryzyko wystąpienia nadmiernej masy ciała. Niewiele jest badań dotyczących wpływu interwencji dietetycznych na ekspresję genu FTO. Tak dalece jak to zostało zbadane wydaje się, że odpowiednie nawyki żywieniowe mogą modyfikować wpływ alleli genu FTO na ryzyko wystąpienia otyłości.

The aim of this study was to determine the association between polymorphism located in exon 8 of PPARGC1A gene (Cys430Ser) and carcass quality in pigs. Experiment was carried out on 350 PIC hybrid fatteners. Polymorphism was analyzed using PCR-RFLP method. The frequency of genotypes was as follows: AA – 0.33, AT – 0.57, TT – 0.1, however alleles: A – 0.62, T – 0.38. In the analyzed population loss of Hardy-Weinberg equilibrium was observed (P ≤ 0.01). Statistical analysis showed that only one of the evaluated traits was associated with individual PPARGC1A genotypes. Cooling loss value for pig carcasses with TT genotype was statistically significant (P ≤ 0.05) higher than observed in those with AA and AT genotypes.
Celem niniejszych badań było wykazanie zależności pomiędzy polimorfizmem zlokalizowanym w 8 eksonie genu PPARGC1A (Cys430Ser) a cechami tuszy świń. Eksperyment został przeprowadzony na 350 tucznikach hybrydowych PIC. Polimorfizm analizowano z użyciem metody PCR-RFLP. Frekwencja genotypów była następująca: AA - 0.33, AT - 0.57, TT - 0.1, natomiast alleli: A - 0.62, T - 0.38. W analizowanej populacji zaobserwowano zachwianie równowagi genetycznej Hardy’ego-Weinberga (P ≤ 0,01). Analiza statystyczna wykazała, że tylko jedna z ocenianych cech była powiązana z poszczególnymi genotypami PPARGC1A. Wartość strat chłodzenia (%) dla świń z genotypem TT była statystycznie istotnie (P ≤ 0,05) wyższa niż obserwowana u osobników z genotypami AA i AT.

Opis:
European white oak species (Quercus sect. Quercus) are known to share a substantial part of their nuclear and cytoplasmic genomes as a result of extensive interspecific hybridization and introgression. We studied natural populations of three species distributed in Slovakia, namely Q. robur, Q. petraea and Q. pubes- cens, which are largely sympatric but have contrasting ecological requirements, using a combination of leaf morphometry, neutral nuclear microsatellite markers (nSSR) and potentially adaptive amplified fragment length polymorphisms (AFLP). Bayesian analysis of population structure relying on nSSR revealed that the degree of admixture was relatively low in Q. robur but higher in Q. petraea and Q. pubescens. The inferred Q. robur ancestry closely correlated with morphometric scores of the canonical discriminant analysis based on 13 leaf traits, while for the other two species the correlation was much weaker. We identified two AFLP fragments associated with climatic variables, mainly with air vapour pressure and characteristics of temper- ature regime at the sites of origin. These associations indicate that climatic adaptation is the mechanism driving interspecific divergence and maintaining integrity of white oak species.

Opis:
Poprzez wskazanie i dyskusję niemożliwych do przyjęcia konsekwencji, jakie niesie propagowany przez Dawkinsa genocentryzm, autorka starała się wykazać, iż nie można go uznać za zasadny paradygmat rozumienia świata. Te same fakty empiryczne interpretować można w odmienny sposób. Dawkins widzi przyrodę jako istniejącą dla dobra genów, istnienie zaś wszystkich innych organizmów, w tym człowieka uznaje za podporządkowane mu. Nieredukcjonistyczna wizja człowieka i innych organizmów żywych związana być jednak musi z inną, niegenocentryczną perspektywą wyjaśniania faktów biologicznych, w tym takich jak np. zjawisko symbiozy, odwzajemnionego i nieodwzajemnionego altruizmu i innych. Genocentryzm widzieć tu można jako interpretacyjną przeszkodę uniemożliwiającą właściwe ich rozumienie. Znacznie zasadniejszy wydaje się więc paradygmat osobnikocentryczny, w świetle którego co prawda nie udało się jeszcze wyjaśnić wszystkiego co dzieje się przyrodzie, lecz który jednak nie wymaga - w przeciwieństwie do genocentryzmu - rezygnacji z holizmu czy też z ujęcia człowieka jako bytu w istocie swej wolnego i odpowiedzialnego za siebie i świat.
Through the indication and criticism of unacceptable consequences that follow the concept of genocentrism, as propagated by Dawkins, the author has endeavoured to show that it cannot be regarded as a justified paradigm of understanding the world. The same empirical facts can be interpreted in different ways. Dawkins sees the nature as existing for the genes' benefit, whereas he regards the existence of all other organisms, including man, as subordinate to it. Non-reductionist vision of man and other living organisms must be, however, connected with another, nongenocentric perspective of explaining biological facts, including such phenomena as symbiosis, both reciprocated and unreciprocated altruism, and other. Genocentrism can be perceived as interpretative obstacle precluding their appropriate understanding. Much more justified seems to be the individualist centric paradigm, in the light of which - to tell the truth - not all that is going on in nature can be explained yet, but which does not require, as opposed to genocentrism, resignation from holism or seeing man as being free in his nature and responsible for themselves and the world.

Mutants with such effects as sixrow and intermedium phenotypes show clear morphological distinctions among different loci, but also among different allelic mutants. These genes, without exception, are capable of unexpected synergistic reinforcing or disturbing intraction, the extremes being typically six-rowed or deformed spikes, respectively. The investigations have centered on 69 intermedium mutants, representing 9 loci, in double mutant combinations, in double combinations with the six-row gene hex-v, in triple combinations with hex-v, and in triple and quadruple mutant combinations. The effects of the interaction may differ among the three characters of lateral floret development, among intermedium loci, and among alleles of the particular locus. Particular types of gene interaction are indicated, particular loci being more competent than others, and the particular alleles being more competent in relation to the constellation of loci. Accumulation of intermedium genes in more complex gene systems leads to progressive promotion of lateral floret development, but there are indications that such systems may be more sensitive to environmental stress, leading to irregular or even deformed spike formation. Probably, representatives of the hex-v locus should form the fundamental constituent in the synthesis of gene systems with the most efficient promotion of lateral floret development in the breeding of six-row barley.

Beal conjecture
Opis:
Praca obejmuje testowanie przypuszczenia Beal'a z wykorzystaniem klasycznych procesorów. Dodatkowo w wybranych funkcjach oprogramowania wykorzystano standard OpenMP, co umożliwiło zrównoleglenie obliczeń. Do obliczeń wykorzystano jednostki obliczeniowe wchodzące w skład komputerów IBM Blue Gene/P, IBM Blue Gene/Q oraz IBM Power 775. Testy wykonano także na superkomputerze HP BladeSystem/Actina, Hydra dostępnym w ICM UW - użyto tam węzła obliczeniowego posiadającego dwa procesory Intel Xeon X5660. Porównano wydajność własnych rozwiązań napisanych w języku C z możliwościami oprogramowania napisanego w języku Python przez Peter'a Novig'a.
This paper includes the testing of Beal’s conjecture using classical processors. Additionally some features of OpenMP standard were used in software what allowed to parallel the calculation. Calculations were based on computational units included in the computers IBM Blue Gene/L, IBM Blue Gene/Q, and the IBM Power 775 tests have been performed on the supercomputer HP BladeSystem / Actina, Hydra available in the ICM UW - computing nodes with Intel Xeon processors X5660 were used there. The performance of own solutions written in C was compared with the capabilities of software written in Python by Peter Novig.

Opis:
Development of metastases is a typical feature of cancer progression and the main cause of treatment failure in cancer treatment. Due to their ability to settle far from original tumor location, cancer cells may preserve the feature of immortal cells, enabling survival of tumor and transition to chronic phase of the disease. Applying currently available techniques of topical treatment, such as surgery and radiotherapy, we are unable to control fully spread of cancer cells, while systemic chemotherapy even in chemosensitive tumors does not eradicate the disease in all cases. Ovarian cancer may spread by dissemination within the abdominal cavity and lymphatic vessels, resulting in distant metastases. The process of metastases’ development is extremely complex, depending on many different factors governing intercellular adhesion and acquisition of ability to move and migrate by cancer cells. Tumors with coexisting distant metastases are considered most advanced, which means also a grim prognosis for the patient. Mechanism of metastases’ development is the subject of several studies, attempting to identify factors which might lendthemselves for targeted therapy of cancers, including ovarian cancer. The paper presents genes, their products and other metastases-associated proteins: HER2 gene, AEG-1 gene, kisspeptin, E-cadherin, survivin, uPAR, clusterin, Met gene, claudins 3 and 4, kallikreins, SDF-1 gene. This paper is meant to systematize extensive knowledge on the development of metastases development and synthetic analysis of data concerning this process.
Przerzutowanie jest cechą charakterystyczną progresji nowotworów złośliwych i główną przyczyną niepowodzeń w leczeniu raka. Dzięki zdolności do występowania w miejscach poza ogniskiem pierwotnym komórki nowotworowe mogą zachować cechę komórek nieśmiertelnych, co pozwala na przetrwanie nowotworu i nazwanie go chorobą przewlekłą. Stosując dostępne dziś metody leczenia miejscowego, takie jak chirurgia i radioterapia, nie jesteśmy w stanie w pełni kontrolować rozprzestrzeniania się komórek nowotworowych, a systemowa chemioterapia w chemiowrażliwych nowotworach nie zawsze „eradykuje” chorobę. Rak jajnika może szerzyć się poprzez rozsiew w jamie brzusznej oraz naczynia chłonne, dając przerzuty odległe. Proces przerzutowania jest niezmiernie złożony, wpływa na niego wiele różnych czynników decydujących o wzajemnym przyleganiu komórek do siebie, nabyciu zdolności ruchliwości i migracji przez komórki nowotworowe. Nowotwory, którym towarzyszą przerzuty odległe, są klasyfikowane jako najbardziej zaawansowane, co oznacza jednocześnie złe rokowanie dla pacjenta. Mechanizm przerzutowania jest przedmiotem wielu badań mających na celu wyłonienie czynników, które mogą być tarczą dla terapii celowanych nowotworów, w tym raka jajnika. W artykule przedstawiono geny i ich produkty oraz inne białka związane z przerzutowaniem: gen HER2, gen AEG-1, kisspeptynę, kadherynę-E, surwiwinę, uPAR, klusterynę, gen Met, klaudyny 3 i 4, kalikreiny, gen SDF-1. Celem pracy było usystematyzowanie obszernej wiedzy na temat przerzutowania oraz syntetyczna analiza danych dotyczących tego procesu.
