Opis:
Inflammatory bowel diseases (IBD) are disorders originated from immune disturbances. The aim of the study was to evaluate the association between the -2518 A/G MCP-1 polymorphism and the risk of IBD development. Material and methods. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Study group consisted of 197 subjects with IBD (120 with ulcerative colitis and 77 with Crohn’s disease) as well as 210 healthy controls. Results. The presence of the -2518 G/G MCP-1 genotype in the investigated groups seems to be connected with higher risk of inflammatory bowel disease as well as Crohn’s disease only (OR 2.26; 95% CI 1.44-3.54 and OR 2.08; 95% CI 1.21-3.46, respectively). Conclusions. Our data showed that the -2518 A/G MCP-1 polymorphism might be associated with the IBD occurrence and might be used as predictive factor of these diseases in a Polish population.

Opis:
Autoimmune thyroid diseases (AITDs), including Hashimoto' s thyroiditis (HT) and Graves' disease (GD), are related to environmental and genetic factors. We analyzed the association of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) gene two polymorphisms (+49 A/G, -318 C/T) with HT and GD development in Polish children, and correlated both polymorphisms with the production of thyroid autoantibodies (TPOAb and TgAb). The study involved 49 AITD patients (age 10-19) with HT (n=25) or GD (n=24) and 69 healthy controls. SNP genotyping was performed using genomic DNA and TaqMan® probes. The obtained results indicated that CTLA-4 +49 GG genotype was significantly more frequent in both HT and GD patients, whereas the AA genotype was more common in controls. CTLA-4-318 CT genotype was significantly more frequent in AITD, and the CC genotype more often occurred in controls. Significantly higher median TPOAb and TgAb values were associated with G allele in HT, and with T allele in GD patients. Concluding, both studied polymorphisms seem to be important genetic determinants of the risk of HT and GD, and appear to be associated with a predisposition to high levels of TAbs and clinical AITD. The obtained results give more information on the distribution of the CTLA-4 polymorphism in Polish AITD children, and further support the proposal that the CTLA-4 gene plays an important role in a TAb production.

Opis:
Epilepsy is one of the most common CNS disorders occurring in approximately 1% of the world population. It is characterized by the occurrence of recurrent attacks of varying symptomatology. It is estimated that 30% of patients, despite the appropriate antiepileptic treatment, still experiencing seizures. In this case we are dealing with so-called the phenomenon of drug resistance. In Poland, this problem concerns about 100–120 thousand patients. Predisposing factors for epilepsy include: onset of symptoms before 1 year of age, high frequency of seizures before treatment and structural changes of the brain, including cortical malformations. Uncontrolled seizures affect the patients quality of life, increasing the risk of injury, affecting the physical well-being and psychosocial functioning. Despite knowing these presumable risk factors for epilepsy, it remains unknown why in the two patients with the same type of epilepsy or the same type of seizure, efficacy of antiepileptic drugs can be extremely different. Potential reasons for this may be genetic factors, changing the pharmacodynamic and pharmacokinetic attributes of antiepileptic drugs. Among these factors is mentioned genetically determined polymorphism of some microsomal enzymes (CYP2C9, CYP2C19), P-glycoprotein, a protein MRP (multidrug resistance-associated protein) and pharmacodynamic malfunction of GABA (GABAA) and ion channels. It seems that research on the mechanisms of drug resistance may lead to the introduction of new therapeutic strategies This article aims to show the impact of genetic factors to the lack of treatment efficacy in epilepsy.
Padaczka jest jedną z najczęstszych chorób ośrodkowego układu nerwowego, występującą u około 1% populacji na świecie. Charakteryzuje się występowaniem nawracających napadów o różnej symptomatologii. Szacuje się, że u 30% pacjentów mimo prowadzonego właściwego leczenia przeciwpadaczkowego nadal występują napady drgawkowe. Jest to tak zwane zjawisko lekooporności. W Polsce problem ten dotyczy około 100 000–120 000 chorych. Czynnikami predysponującymi do wystąpienia padaczki lekoopornej są: ujawnienie się choroby przed 1. rokiem życia, duża częstotliwość napadów przed rozpoczęciem leczenia oraz zmiany strukturalne mózgu, w tym wady rozwojowe kory mózgowej. Niekontrolowane napady padaczkowe pogarszają jakość życia chorych, zwiększając ryzyko urazów, wpływając negatywnie na samopoczucie fizyczne oraz funkcjonowanie psychospołeczne. Chociaż znane są potencjalne czynniki ryzyka, to nadal nie wiadomo, dlaczego u dwóch pacjentów z tym samym rodzajem padaczki lub tym samym typem napadów skuteczność leczenia lekami przeciwpadaczkowymi może być skrajnie różna. Wśród możliwych przyczyn tego zjawiska wymienia się czynniki genetyczne, zmieniające właściwości farmakodynamiczne i farmakokinetyczne stosowanych leków. Do grupy tych czynników zalicza się: genetycznie uwarunkowany polimorfizm niektórych enzymów mikrosomalnych (CYP2C9, CYP2C19), glikoproteiny P, białka MRP (multidrug resistance-associated protein) oraz zaburzenia funkcji farmakodynamicznych receptorów GABA (GABAA) i kanałów jonowych. Wydaje się, że badania nad mechanizmami lekooporności mogą skutkować wprowadzeniem nowych strategii terapeutycznych. Niniejszy artykuł ma na celu przedstawienie wpływu powyżej wymienionych czynników genetycznych na brak skuteczności leczenia w padaczce.

Opis:
Matrix metalloproteinase-2 (MMP-2) is an enzyme with proteolytic activity against matrix proteins, particularly basement membrane constituents. A single nucleotide polymorphism (SNP) at -1306, which disrupts a Sp1-type promoter site (CCACC box), displayed a strikingly lower promoter activity with the T allele. In the present study, we investigate whether this MMP-2 SNP is associated with susceptibility to breast cancer in the Saudi population. Ninety breast cancer patients and 92 age matched controls were included in this study. TaqMan Allele Discrimination assay and DNA sequencing techniques were used for genotyping. The results showed that, the frequency of MMP-2 CC wild genotype was lower in breast cancer patients when compared with healthy controls (0.65 versus 0.79). The homozygous CC (OR=2, χ2=5.36, p=0.02) and heterozygous CT (OR=1.98, χ2=4.1, p=0.04) showing significantly high risk of breast cancer in the investigated group. In conclusion our data suggest that the MMP-2 C-1306T polymorphism may be associated with increased breast cancer risk in the Saudi population.

Aims. This study aimed to investigate CHRNA3 (rs8040868) and PHACTR2 (rs9390123) single-nucleotide polymorphisms (SNPs) for association with non-small-cell lung cancer (NSCLC) risk in a Chinese population, and whether the environment affects the genetic polymorphisms. Methods. This case and control study included 500 NSCLC patients and 500 age-matched healthy controls. CHRNA3 (rs8040868) and PHACTR2 (rs9390123) SNPs were genotyped and associated for NSCLC risk by computing the odds ratio and 95% confidence interval from multivariate unconditional logistic regression analyses with adjustment of age. Results. The minor allele frequency (MAF) of CHRNA3 (rs8040868) and PHACTR2 (rs9390123) was 0.350 (C) and 0.397 (C), respectively. The frequencies of genotype and allele in CHRNA3 (rs8040868) and PHACTR2 (rs9390123) were not significantly different between the cases and controls, or between either of the subgroups. Conclusion. Although rs8040868 and rs9390123 SNPs are not associated with NSCLC risk in Chinese population, the results strongly suggest that geographical agents interact with human genetic polymorphism independent of ethnic background.

Opis:
Introduction: According to the World Health Organization about 350 million people around the world are affected by depression. Despite the high prevalence of this disease the mechanism of depression origination as well as the causes of the resistance to therapy are still not fully understood. ABCB1 gene encode P glycoprotein which is one of the components of blood-brain barrier. The main function of this protein is the efflux of many toxic compounds, including drugs, which may indicate potential association between the proper functioning of P glycoprotein and the susceptibility to the development of depressive disorders or the failure of antidepressant therapy. The objective of this study was to evaluate single nucleotide polymorphism (SNP) C1236T of the ABCB1 gene in the group of patients with recurrent depressive disorder (rDD) and to estimate the possible association of this polymorphism with the response to antidepressant therapy. Material and methods: C1236T was evaluated in 30 patients with rDD. Genotyping was performed using automated sequencing (the Sanger method). The results were compared with those obtained from the control group which consisted of 96 blood donors from the local blood bank. Results: No statistically significant difference in the frequency of genotypes (p=0.0665) and allele (p=0.1489) for the SNP C1236T of ABCB1 gene was found between the patients with rDD and the control group. No correlation between C1236 and the age when the disease was stated (p=0.0807). Neither the association between genotypes and the severity of depressive symptoms before treatment (p=0.7956) nor the association with effectiveness of the therapy (p=0.2051) were found. Conclusions: On the basis of the results of the preliminary study, C1236T of ABCB1 gene have no influence on the predisposition to rDD, the severity of depressive symptoms and the efficiency of antidepressant therapy have not been stated, either.
Streszczenie Wstęp: Według danych Światowej Organizacji Zdrowia depresja dotyka około 350 milionów osób na całym świecie. Jednak pomimo powszechnego występowania, zarówno etiologia tej choroby, jak i przyczyny oporności na leczenie w dalszym ciągu nie są w pełni poznane. Gen ABCB1 koduje glikoproteinę P, która jest jednym z elementów bariery krew-mózg. Główną funkcją białka jest usuwanie związków toksycznych, w tym także leków, co może wskazywać na potencjalny związek między prawidłowym działaniem glikoproteiny P a predyspozycją do rozwoju zaburzeń depresyjnych czy niepowodzeniem terapii lekami przeciwdepresyjnymi. Celem pracy była ocena polimorfizmu pojedynczego nukleotydu (ang. single nucleotide polymorphism - SNP) C1236T genu ABCB1 wśród chorych na zaburzenia depresyjne nawracające (ang. recurrent depressive disorder - rDD) oraz oszacowanie potencjalnego związku tego polimorfizmu z odpowiedzią na terapię lekami przeciwdepresyjnymi. Materiał i metody: Polimorfizm C1236T oceniono w grupie 30 pacjentów, u których zdiagnozowano rDD. Genotyp określono wykorzystując technikę automatycznego sekwencjonowania metodą Sangera. Otrzymane wyniki porównano z wynikami grupy kontrolnej, którą stanowiło 96 dawców krwi z lokalnego banku krwiodawstwa. Wyniki: Nie stwierdzono istotnych statystycznie różnic w częstości występowania poszczególnych genotypów (p=0,0665) i alleli (p=0,1489) polimorfizmu C1236T genu ABCB1 między grupą pacjentów z rDD a grupą kontrolną. Nie wykazano również zależności pomiędzy C1236T a wiekiem w chwili diagnozy rDD (p=0,0807), nasileniem objawów depresji przed rozpoczęciem terapii (p=0,7956) czy skutecznością leczenia przeciwdepresyjnego (p=0,2051). Wnioski: Na podstawie wyników badania wstępnego, stwierdzono brak wpływu polimorfizmu C1236T genu ABCB1 na predyspozycję do rozwoju rDD, nasilenie objawów depresji w chwili diagnozy czy skuteczność terapii przeciwdepresyjnej.

Opis:
Nephrotic syndrome (NS) is the most common reason of proteinuria in children and can be caused by the pathology of renal glomeruli. Steroid therapy is typically used in this disorder. It has been shown that MIF is a cytokine which counteracts the immunosuppressive properties of glucocorticoids. The aim of this study was looking for a correlation between MIF polymorphisms and genetic susceptibility to steroid resistance in children with INS (Idiopathic NS). Methods: The study was performed in 71 patients with INS including SRNS (steroid resistance nephrotic syndrome) (41) and SSNS (steroid sensitive nephrotic syndrome) (30) and in 30 control subjects. We employed Sanger sequencing and capillary electrophoresis. Linkage disequilibrium was made using Haploview and PHASE. Results: We didn't observe a statistical significance between SNPs detected in patients with INS and controls. Our studies revealed statistical significance for two polymorphisms: rs2070767C > T and rs2000466T > G between patients with SRNS and SSNS. The results for rs34383331T > A are close to being statistically significant. Statistical significance was revealed for CATT5/CATT6 genotype in SRNS group vs SSNS group (OR=4.604, 95%CI=1.356-15.632, p=0.0168). We found that the frequency of 5/X-CATT genotype compared with X/X-CATT genotype was significantly higher in SRNS patients vs SSNS (OR=3.167, 95%CI=1.046-9.585, p=0.0426). In linkage disequilibrium analysis we didn't show involvement in susceptibility to INS and steroid sensitive phenotype. Conclusions: Our results suggest that the role of MIF polymorphisms in the susceptibility to positive response to steroid therapy is still unresolved. It indicates that MIF may be involved in indirect and complex molecular mechanisms of steroid activity in hormone-dependent metabolic pathways in children with INS. Because of ambiguous findings, pleiotropic features of this cytokine require that more research should be undertaken.

Opis:
Plant glutathione peroxidases are an important class of enzymes which play key roles in the stress adaptability of plants both in context of biotic and abiotic stress pathways. They have been over the years much studied in animals since the catalytic residues are comprised of selenocysteine a variant amino acid which is ribosomally encoded with the help of an RNA structural element known as SECIS. Various workers over the years have shown that plant glutathione peroxidases play active roles in ROS sequestration, lipid hydroperoxidation as well as regulate glutathione levels. However, each plant has various patterns of glutathione peroxidase expression and action and in some plants certain isoforms have not been detected at all. This work focuses on the prediction and identification of single nucleotide polymorphisms (SNPs) and INDELs in the coding regions of plant glutathione peroxidases, with the help of a Bayesian based algorithm subsequently validated. A large number of informative sites were detected 279 of which had variant frequency of ≥ 50 %. This data should be beneficial for future studies involving genetic manipulation and population based breeding experiments.

Opis:
UBE2E2 encodes ubiquitin-conjugating enzyme E2E2, which plays an important role in the synthesis and secretion of insulin. Two previous studies indicated that SNPs in UBE2E2 were associated with risk for type 2 diabetes mellitus (T2DM) in the Japanese and Korean populations, respectively. We examined the association of one SNP in this gene, rs7612463, with the risk of T2DM in 1957 Han participants in northeastern China, using an SNPscanTM Kit. rs7612463 genotype was significantly associated with risk for T2DM under various genetic models, including an additive model (P = 0.004), a dominant model (P = 0.024), and a recessive model (P = 0.008). The AA genotype was associated with a significantly decreased risk for T2DM (P = 0.004, OR = 0.513, 95% CI = 0.325-0.810) after adjustment for age, gender, and BMI. The heterozygous genotype, AC, was associated with increased risk for total cholesterol (mmol l-1; P = 0.031) and triglycerides (mmol l-1; P = 0.039) in control individuals. Our results show that rs7612463 is associated with T2DM, with homozygotes of the AA genotype at decreased risk for T2DM in the Chinese population. Additionally, heterozygotes may have decreased risk of T2DM due to insulin resistance.

Objectives Traffic-related particulate matter (PM) is one of the major sources of air pollution in metropolitan areas. This study is to observe the interactive effects of gene and fine particles (particles smaller than 2.5 μm – $\text{PM}_\text{2.5}$) on the respiratory system and explore the mechanisms linking $\text{PM}_\text{2.5}$ and pulmonary injury. Material and Methods The participants include 110 traffic policemen and 101 common populations in Shanghai, China. Continuous 24 h individual-level $\text{PM}_\text{2.5}$ is detected and the pulmonary function, high-sensitivity C-reactive protein (hs-CRP), Clara cell protein 16 (CC16) and the polymorphism in CXCL3, NME7 and C5 genes are determined. The multiple linear regression method is used to analyze the association between $\text{PM}_\text{2.5}$ and health effects. Meanwhile, the interactive effects of gene and $\text{PM}_\text{2.5}$ on lung function are analyzed. Results The individual $\text{PM}_\text{2.5}$ exposure for traffic policemen was higher than that in the common population whereas the forced expiratory volume in 1 s (FEV₁), the ratio of FEV₁ to forced vital capacity (FEV₁/FVC) and lymphocytes are lower. In contrast, the hs-CRP level is higher. In the adjusted analysis, $\text{PM}_\text{2.5}$ exposure was associated with the decrease in lymphocytes and the increase in hs-CRP. The allele frequencies for NME7 and C5 have significant differences between FEV₁/FVC ≤ 70% and FEV₁/FVC > 70% participants. The results didn’t find the interaction effects of gene and $\text{PM}_\text{2.5}$ on FEV₁/FVC in all the 3 genes. Conclusions The results indicated that traffic exposure to high levels of $\text{PM}_\text{2.5}$ was associated with systemic inflammatory response and respiratory injury. Traffic policemen represent a high risk group suffering from the respiratory injury.

Opis:
Compared to angiosperms, conifers represent more complex genomes with larger giga-genome size. To detect large-scale single nucleotide polymorphisms (SNPs), whole genome sequencing of a conifer population is still unaffordable. In this work, we report the use of DNA specific-locus amplified fragment sequencing (SLAF-seq) for large-scale SNP detection in Chinese fir (Cunninghamia lanceolata (Lamb.) Hook), an ecological and economic important conifer in China. SLAF libraries of 18 parent clones of a Chinese fir 2.5 generation seed orchard were sequenced and a total of 117,924 SLAFs were developed. We detected 147,376 SNPs from these SLAFs; 146,231 of them represented simple nucleotide change in A/G, C/T, A/C, A/T, C/G or G/T. The most frequent SNPs occurred in C/T (34.3%), while the majority of SNPs (68.2%) belonged to transition events (A/G and C/T). Notably, all the sequenced samples had high portion (78.2–80.9%) of common SNPs indicating that the Chinese fir genomes tended to change its nucleotides at common loci. 48,406 informative SNPs were then successfully utilized to genotype the tested samples (n = 18) followed by a phylogenetic tree to clarify their genetic relationship. Furthermore, a set of very high linkage disequilibrium (0.51–1.00) were identified from these informative SNPs. In brief, our work demonstrated that SLAF-seq is an alternative and cost-effectively high-throughput approach for large-scale SNP exploitation in Chinese fir. While the obtained SNPs offer useful marker resource for further genetic and genomic studies and will be helpful for Chinese fir breeding programs.

Opis:
Background. The mechanism of steroid resistance in children with the nephrotic syndrome is yet unknown. About 20% of patients demonstrate steroid unresponsiveness and progress to end stage renal disease. Aberrant SOCS3 and SOCS5 expression in steroid resistant and sensitive patients has previously been demonstrated. Here, we investigate genetic and epigenetic mechanisms of regulation of SOCS3 and SOCS5 transcription in nephrotic children. Methods. 76 patients with the nephrotic syndrome (40 steroid resistant and 36 steroid sensitive) and 33 matched controls were included in this study. We performed genotyping of a total of 34 single nucleotide polymorphisms for SOCS3 and SOCS5 promoters and evaluated their methylation status using MS-PCR and QMSP methods. Results. Steroid resistant patients had a significantly lower methylation of one region of SOCS3 promoter in comparison with steroid sensitive patients and controls (p < 0.0001). However, the relative methylation level in the steroid sensitive patients and controls differed significantly even before the first steroid dose (p = 0.001758). Other SOCS3 and SOCS5 promoter regions displayed no differences in methylation or were fully methylated/unmethylated in all study groups, showing site-specific methylation. The allele and genotype distribution for SOCS3 and SOCS5 markers did not differ statistically between the groups. Conclusions. We demonstrate an epigenetic mechanism of SOCS3 up-regulation in steroid resistant children with the nephrotic syndrome. The assessment of methylation/unmethylation of SOCS3 promoter might be an early marker for steroid responsiveness in NS patients.

Opis:
Wstęp i cel: Wielu autorów podkreśla fakt zmniejszonego progu bólowego, a także tolerancji na ból u sportowców. Wciąż jednak nie wiadomo, w jakim stopniu mają w tym udział czynniki genetyczne, a w jakim psychologiczne i psychospołeczne. Celem niniejszej pracy jest przedstawienie możliwych mechanizmów wpływających na różnice w percepcji bólu. Materiał i metody: Na podstawie dostępnego piśmiennictwa autorzy opisali metody pomiaru natężenia bólu oraz przedstawili możliwe źródła różnic w percepcji bólu u zawodników sportów walki w stosunku do osób nieuprawiających zawodowo sportu. Wyniki: Opracowano poszczególne czynniki mogące wpływać na percepcję bólu u sportowców. Wniosek: Mimo braku różnic genetycznych w polimorfizmach pojedynczych nukleotydów genów OPRM1 i COMT, zanotowano istotne różnice w metodach radzenia sobie ze stresem oraz w natężeniu cech temperamentu między zawodnikami sportów walki a grupami kontrolnymi. Prawdopodobne, że cechy temperamentu wpływają na wypracowanie określonych strategii radzenia sobie z bólem.
Introduction and aim: Many authors emphasise lower pain threshold and pain tolerance among athletes. Though, it is not known to what degree genetic, psychological and psychosocial factors are involved. The aim of this paper is to present possible mechanisms affecting the differences in pain perception. Material and methods: On the grounds of the available literature, the authors describe the pain measure methods and present the possible source of the pain perception differences in martial arts athletes compared to non-athletes. Results: Several factors likely to be involved in pain perception among athletes has been elaborated. Conclusion: Although, there have been no differences in single nucleotide polymorphisms in genes OPRM1 and COMT, significant differences in stress coping strategies and temperament traits between martial arts athletes and control groups have been found. Presumably, temperament traits influence the development of particular pain coping strategies.
