Opis:
Genetic factors may play a role in the etiology of depressive disorder. The type 2 iodothyronine deiodinase gene (DIO2) encoding the enzyme catalyzing the conversion of T4 to T3 is suggested to play a role in the recurrent depressive disorder (rDD). The current study investigates whether a specific single nucleotide polymorphism (SNP) of the DIO2 gene, Thr92Ala (T/C); rs 225014 or ORFa-Gly3Asp (C/T); rs 12885300, correlate with the risk for recurrent depression. Genotypes for these two single nucleotide polymorphisms (SNPs) were determined in 179 patients meeting the ICD-10 criteria for rDD group and in 152 healthy individuals (control group) using a polymerase chain reaction (PCR) based method. The specific variant of the DIO2 gene, namely the CC genotype of the Thr92Ala polymorphism, was more frequently found in healthy subjects than in patients with depression, what suggests that it could potentially serve as a marker of a lower risk for recurrent depressive disorder. The distribution of four haplotypes was also significantly different between the two study groups with the TC (Thr-Gly) haplotype more frequently detected in patients with depression. In conclusion, data generated from this study suggest for the first time that DIO2 gene may play a role in the etiology of the disease, and thus should be further investigated.

Opis:
The aim of this study was to identify SNPs in leptin (LEP), leptin receptor (LEPR) and growth hormone (GH) genes in order to analyze genetic diversity of Slovak Spotted cattle. The total numbers of blood samples were taken from 353 Slovak Spotted cows originating from four farms. Genomic DNA was isolated by phenol-chloroform extraction method and analyzed by PCR-RFLP method. After digestion with restriction, enzymes were detected in whole population of cow's alleles with frequency: LEP/Sau3AI A 0.84 and B 0.16 (±0.0152); LEPR/BseGI C 0.95 and T 0.05 (±0.0089) and GH/AluI L 0.70 and V 0.30 (±0.0188). Based on the observed vs. expected genotypes frequencies populations across loci were in Hardy-Weinberg equilibrium (P\>0.05). Predominant for SNP LEP/Sau3AI was AA genotype (0.70), for SNP LEPR/T945M CC genotype (0.91), and LL genotype (0.48) was most frequent for SNP GH/AluI. The observed heterozygosity of SNPs across populations was also transferred to the low or median polymorphic information content 0.24 (He 0.28), 0.08 (He 0.09) and 0.33 (He 0.47) for LEP, LEPR and GH genes, respectively. Within genetic variability estimating negative values of fixation indexes FIS (-0.09-0.05) and FIT (-0.07-0.03) indicating heterozygote excess were observed. The value of FST indexes (0.018-0.023) shows very low levels of genetic differentiation in allele frequencies of loci among evaluated subpopulations. The low values of genetic distances (0.0018-0.0159) indicated high genetic relatedness among animals in subpopulations caused probably by common ancestry used in breeding program at farms.

Opis:
Vitamin D3 (1,25(OH)2D3 (1,25-dihydroxyvitamin D3)) is a hormone playing a crucial role in numerous biological processes in the human body, including induction and control of cell proliferation and differentiation. Numerous data relate the vitamin D3 level with various types of cancer. It has been suggested that SNPs in the vitamin D3 receptor (VDR) gene might influence both the risk of cancer occurrence and cancer progression. The aim of this study was to search for genetic correlations between individual SNPs in the VDR gene and the risk of oral cavity carcinoma. Two SNPs were selected based on the literature and our previous results. Seventy-three patients with squamous cell carcinoma of the head and neck and one hundred control subjects were investigated. Two SNPs in the VDR gene were genotyped in minisequencing reactions followed by capillary electrophoresis. Hardy-Weinberg equilibrium (HWE), the χ2 test and logistic regression were used for statistical analysis. The SNP rs2238135 in the VDR gene displayed statistical differences in frequency between the tested groups (p=0,0007). Furthermore, the G/C genotype of the rs2238135 in the VDR gene was characterized by a 3.16 fold increased risk of oral cavity carcinoma. The obtained results provide evidence for a genetic association between rs2238135 in the VDR gene and the occurrence and risk of oral cavity cancer.

The aim of the study: We evaluated the connection between the presence of the -2518 A/G MCP-1 as well as 190 G/A CCR2 polymorphic variants and colorectal cancer (CRC) occurrence. Material and methods: Study group consisted of subjects with different stages of CRC as well as healthy controls. Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: W observed an association between the colorectal cancer and the GG genotype of the -2518 A/G MCP-1 single nucleotide polymorphism. No statistically significant correlation was found between CRC and the 190 G/A CCR2 polymorphism. Conclusion: The results of this study support the hypothesis that polymorphism in the MCP-1 gene may contribute to the etiology of colorectal cancer.

Opis:
Polymerase chain reaction-restriction fragment length polymorphism (RFLP-PCR) is a technique used to identify single nucleotide polymorphisms (SNPs) based on the recognition of restriction sites by restriction enzymes. RFLP-PCR is an easy-to-perform and inexpensive tool for initial analysis of SNPs potentially associated with some monogenic diseases, as well as in genotyping, genetic mapping, lineage screening, forensics and ancient DNA analysis. The RFLP-PCR method employs four steps: (1) isolation of genetic material and PCR; (2) restriction digestion of amplicons; (3) electrophoresis of digested fragments; and (4) visualisation. Despite its obsolescence and the presence of high-throughput DNA analysis techniques, it is still applied in the analysis of SNPs associated with disease entities and in the analysis of genetic variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). RFLP-PCR is a low-cost and low-throughput research method allowing for the analysis of SNPs in the absence of specialised equipment, and it is useful when there is a limited budget.

This study aimed to investigate the associations of hepatocyte nuclear factor 4 (HNF4) alpha single nucleotide polymorphisms (SNPs) and haplotype with insulin resistance and metabolic syndrome parameters. Nine SNPs spanning the HNF4 alpha P2 promoter (rs4810424, rs1884613 and rs1884614) and coding region (rs2144908, rs6031551, rs6031552, rs1885088, rs1028583 and rs3818247) were genotyped in 160 subjects without diabetes or metabolic syndrome. The HNF4 alpha P2 promoter SNPs rs4810424, rs1884613 and rs1884614 were associated with insulin resistance (p = 0.017; 0.037; 0.024) and body mass index (BMI) (p = 0.03; 0.035; 0.039). The intron 1D SNP rs2144908 was associated with high-density lipoprotein cholesterol (HDLc) (p = 0.020) and the intron 9 SNP rs3818247 showed association with systolic (p = 0.02) and diastolic (p = 0.034) blood pressure. HNF4 alpha common haplotype CCCGTC associated with higher insulin resistance (p = 0.022), fasting blood glucose (FBG) (p = 0.035) and lower HDLc (p = 0.001). In conclusion, subjects with HNF4 alpha P2 variants and haplotypes have been shown to have a higher insulin resistance and are therefore at a higher risk for developing type 2 diabetes mellitus.

Opis:
Local adaptation is a key concept in biology: shift of genetic structures of populations due to differential survival of genotypes is expected to lead to phenotypes providing an advantage in the local environment. Variation of sequences of twelve candidate genes was investigated in 13 Norway spruce (Picea abies (L.) Karst.) provenances originating from sites distributed along an altitudinal gradient from 550 to 1300 m a.s.l. Signals of selection were assessed in 103 single nucleotide polymorphisms (SNP). The Bayesian FST-outlier identification methods as implemented in the programs BayeScan and Arlequin did not identify any SNP with a clear evidence of selection. The approaches relying on SNP-climate associations (spatial analysis method based on logistic regression of allele frequencies with environmental variables, Bayesian method applied in BayEnv2) identified several relationships but none of them remained significant after correction for multiple testing. Gene flow, epigenetic inheritance and former management of the studied populations are discussed as potential reasons for this weak evidence of selec- tion signals.

Opis:
SNP sites are generally discovered by sequencing regions of the human genome in a limited number of individuals. This may leave SNP sites present in the region, but containing rare mutant nucleotides, undetected. Consequently, estimates of nucleotide diversity obtained from assays of detected SNP sites are biased. In this research we present a statistical model of the SNP discovery process, which is used to evaluate the extent of this bias. This model involves the symmetric Beta distribution of variant frequencies at SNP sites, with an additional probability that there is no SNP at any given site. Under this model of allele frequency distributions at SNP sites, we show that nucleotide diversity is always underestimated. However, the extent of bias does not seem to exceed 10-15% for the analyzed data. We find that our model of allele frequency distributions at SNP sites is consistent with SNP statistics derived based on new SNP data at ATM, BLM, RQL and WRN gene regions. The application of the theory to these new SNP data as well as to the literature data at the LPL gene region indicates that in spite of ascertainment biases, the observed differences of nucleotide diversity across these gene regions are real. This provides interesting evidence concerning the heterogeneity of the rates of nucleotide substitution across the genome.

Here, we have developed a highly sensitive, real-time allelic discrimination assay enabling detection of the Y831C mutation in the POLG1 gene. The Y831C mutation is present in the Polish population at a frequency of 2.25%. The new assay is well suited to both extensive population studies and molecular diagnostics of POLG1.

Introduction. Hepatitis C virus (HCV) infection is a global health problem which can lead to liver cirrhosis or hepatocellular carcinoma in one-fifth of chronically infected patients. Materials and methods. The study group consisted of 123 patients: 90 with HCV mono- and 33 with HIV/HCV co-infection, who were treated with pegylated interferon alfa (Peg-IFN-α) and ribavirin. We analyzed selected pretreatment factors: age, sex, HIV/HCV co-infection, grade of inflammation, necrotic changes and fibrosis in histological analysis of liver bioptates, HCV viral load, HCV genotypes, and single nucleotide polymorphisms (SNPs) of IL28B and tried to find out which of them influence sustained virological response (SVR). The IL28B SNP C/T (rs12979860) was analyzed using Custom® SNP Genotyping Assays (Applied Biosystems). Results. Multivariate analysis demonstrated that after adjusting for the other variables three predictors independently influence SVR, namely genotype 3 of HCV, presence of the CC genotype and age >40 years (OR respectively 15.14, 3.62, and 0.36). HCV mono-infected patients were infected with HCV genotype 3 or 4 less frequently (p=0.0001) compared to HIV/HCV co-infected individuals. In patients with HIV/HCV co-infection the CC variant occurred more frequently whereas CT was found less frequently (p=0.001, p=0.0146, respectively). In patients with HIV/HCV co-infection, 3 and 4 genotype of HCV occurred more frequently compared to patients with HCV mono-infection (p=0.0001). Conclusions. These data suggest that age, HCV genotype and IL28B polymorphism are useful for prediction of the response to treatment with Peg-IFN-α and ribavirin. The more frequent occurrence of HCV genotypes 3 or 4 in patients with HIV/HCV co-infection could be associated with the route of transmission.

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.

Introduction: Different pathological processes can deteriorate kidney function and cause ireversible degeneration of its structure; however, an optimal way to inhibit or slow down progression of renal damage is unforunately not available. In the light of promissing data concerning homeodomain-interacting protein kinase 2 (HIPK2) upregulation in damaged kidneys animal model, and increased levels of this protein in patients with various kidney diseases, the influence of rs7456421 and rs 2030712 single nucleotide polimorphisms of HIPK2 gene on chronic kidney disease incidence and progression was studied. Material and methods: In 109 family ‘trios’, consisting of an affected child with CKD (48 females and 61 males, mean age 15.5 ±6.45 years) and both his/her parents, using Transmission Disequilibrium Test allele was used for the transfer of aforementioned SNPs from biological parents to their affected offspring. Results: No statistical significance of allele transfer was found, which means that there were no associations between rs7456421 and rs 2030712 SNPs of HIPK2 gene and the incidence of renal dysfunction. Multiple stepwise regression showed a history of chronic glomerulonephritis (OR=17.3), chronic interstitial nephritis without urinary tract defect (OR=4.4), and CT genotype of rs 2030712 SNP (OR=2.6) as determinant of a more rapid progression of renal dysfunction, in contrast to the protective action of body mass index (OR=0.86). Conclusions: On the basis of TDT results, the influence of rs7456421 and rs 2030712 SNPs of HIPK2 gene on prevalence of chronic kidney disease was not identified. Further studies are needed to ascertain the tight relationships of HIPK2 gene polymorphisms with CKD of different etiologies.

Chronic kidney disease (CKD) is an important challange for healthcare systems wordwide because of its high prevalence and serious late complications. The results of recent studies suggest an association between CKD development and genetic variation within the uromodulin gene (UMOD). The aim of this study was to investigate associations between two common single nucleotide polymorphisms – rs12917707 and rs11864909, located in the region of UMOD and chronic renal disease. The study group consisted of 109 patients with chronic kidney disease, caused by chronic renal glomerulonephritis or chronic tubulointerstitial nephritis, and 109 pairs of their biological parents. Genotyping for rs12917707 and rs11864909 was carried out using the TaqMan Pre-designed SNP Genotyping Assay. In the transsmission disequilibrium test, allele C of rs11864909 was preferentialy transmitted from parents to the children with chronic tubulointerstinal nephritis. The rs12917707 was not associated with CKD. Neither of the investigated polymorphisms was associated with the progression of chronic kidney disease. The obtained results suggest an association of rs11864909 with chronic kidney disease secondary to chronic tubulointerstinal nephritis.

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:
W ostatnich dwóch dekadach zaobserwowano znaczący wzrost tempa rozwoju zróżnicowanych systemów markerów molekularnych oraz odpowiadających im zaawansowanych platform detekcyjnych. Markery oparte na polimorfizmach pojedynczego nukleotydu (SNP), ze względu na częstość ich występowania w genomach bardzo szybko zyskały uznanie w badaniach z zakresu hodowli molekularnej roślin. Wśród najczęściej wykorzystywanych technik genotypowania polimorfizmów pojedynczego nukleotydu znajdują się sondy TaqMan®, mikromacierze DNA, oraz technologia genotypowania przez sekwencjonowanie (GBS). W celu obniżenia kosztów genotypowania opracowano również techniki oparte na standardowej reakcji łańcuchowej polimerazy z zastosowaniem zmodyfikowanych starterów, między innymi technikę tetra-primer ARMS-PCR. W niniejszej pracy zidentyfikowano pięć markerów SNP zasocjowanych z genetycznymi determinantami kształtu korzenia spichrzowego marchwi oraz dokonano ich przekształcenia do markerów wykrywalnych przy zastosowaniu technologii TaqMan® oraz tetra-primer ARMS-PCR. Przydatność wymienionych technik zweryfikowano poprzez genotypowanie 40 wybranych odmian populacyjnych marchwi typu zachodniego. Przeanalizowano zbieżność wyników identyfikacji genotypów otrzymanych przy zastosowaniu wyżej wymienionych technik oraz metody referencyjnej GBS. Techniki te oceniono pod kątem możliwości wykorzystania ich do opracowania wiarygodnych markerów specyficznych zasocjowanych z genetycznymi determinantami kształtu korzenia marchwi.
Over the last two decades a significant increase has been observed in the pace of development of diverse systems of molecular markers and the corresponding advanced detection platforms. Owing to their ubiquity in genomes, markers based on single nucleotide polymorphism (SNP) promptly gained recognition within research on molecular breeding of plants. Amongst the most widely used genotyping techniques of a single nucleotide polymorphisms are the TaqMan® probes, DNA micro-arrays and the genotyping-by-sequencing (GBS) technology. Techniques based on standard polymerase chain reaction with the use of modified primers, including the tetra-primer ARMS-PCR technique, have also been devised with in order to decrease the costs of genotyping. The current work identifies five SNP markers associated with genetic determinants of the shape of carrot taproot and converts them into markers detectable by the TaqMan® and tetra-primer ARMS-PCR technologies. The usefulness of the above techniques has been verified by genotyping 40 selected cultivars of Western-type carrot. The present authors have also analysed the convergence of the results obtained through the mentioned techniques and a GBS reference method. The techniques have been evaluated in terms of their usefulness for designing reliable specific markers associated with genetic determinants of the shape of the carrot root.
