Background. Single-nucleotide polymorphisms in microRNAs play important roles in oncogenesis and cancer development.Objective. We aim to explore whether miR-646 rs6513497 is associated with the risk of hepatocellular carcinoma.Methods. Total 997 HCC patients and 993 cancer-free controls were enrolled in this study. Genotyping was performed using MassARRAY method.Results. Compared with the T allele of rs6513497, the G allele was associated with a significantly decreased risk of HCC (OR = 0.788, 95% CI = 0.631–0.985,P= 0.037); moreover, a more protective effect of the G allele was shown in males (OR = 0.695, 95% CI = 0.539–0.897,P= 0.005 in HCC and OR = 0.739, 95% CI = 0.562–0.972,P= 0.030 in HBV-related HCC), basically in a dominant manner (HCC: OR = 0.681, 95% CI = 0.162–0.896,P= 0.006; HBV-related HCC: OR = 0.715, 95% CI = 0.532–0.962,P= 0.027).Conclusions. Our findings support the view that the miR-646 SNP rs6513497 may contribute to the susceptibility of HCC.

Background: This study aims to investigate the relation between Survivin gene polymorphisms, and the risk of Hepatocellular carcinoma (HCC) resulting from hepatitis C infection among Egyptian population. Methods: This prospective study was conducted on 164 patients, 57 patients were diagnosed with hepatitis C, where other 57 were diagnosed with HCC in addition to 50 healthy volunteers as controls. Genotyping for Survivin rs1042489 and rs8073069 single nucleotide polymorphisms was carried out by the allelic discrimination Real-Time Polymerase Chain Reaction Single Nucleotide Polymorphisms genotyping technology. Results: The results of Survivin rs1042489 polymorphism, revealed that the TC and CC genotypes were significantly different between hepatocellular carcinoma patients (OR=15.5, 95%CI: 3.299-72.825,P<0.001), and controls (OR=44, 95%CI: 8.025-241.254, P<0.001). Furthermore, CC genotype was significantly different between cirrhotic and hepatocellular carcinoma patients (OR=19.2, 95%CI: 3.097-119.049, P=0.002). Moreover the TC genotype shows a significant different between controls and cirrhotic patients (OR=5.5, 95%CI: 2.111-14.328, P<0.001). However when comparing TT genotypes, CC+TC genotypes results showed a significant association with increasing the risk of cirrhosis and hepatocellular carcinoma (OR=4.812, 95%CI: 1.893-12.233, P=0.001), (OR=21.607, 95%CI: 4.738-98.532, P<0.01), respectively. On the other hand, there was no significant difference among all studied groups for all genotypes, regarding Survivin rs8073069. Also CC+GC genotype showed no significant association with increased the risk of hepatocellular carcinoma (P=0.999) compared with the GG genotypes. Conclusion: The study indicates that functional Survivin rs1042489 polymorphism may contribute to the risk of hepatocellular carcinoma while Survivin rs8073069 polymorphism has no significant association with increased risk of hepatocellular carcinoma among the studied groups.

Objective. To analyze associations between single-nucleotide polymorphisms (SNPs) in some genes located on the X chromosome and risks for hepatocellular carcinoma (HCC) in Yakut males with chronic hepatitis C infection (HCV). Patients and methods. We examined 140 Yakut males with chronic HCV in the stage of liver cirrhosis formation. In 41 of them, chronic hepatitis was complicated by HCC. All patients were tested for SNPs in the genes located on the X chromosome, including TLR7 (rs179008); TLR7 (rs179009); TLR8 (rs3764879); TLR8 (rs3764880); IRAK1 (rs3027898); MECP2 (rs1734791); TAB3 (rs1000129516); ELK1 (rs1000619237); GPC3 (rs2267531). Results. We found no significant differences in the frequencies of specific alleles of genes involved in TLR7 signaling between patients with chronic HCV and patients with HCC. However, there were significant differences in the distribution of variable sites in the rs2267531 locus of the GPC3 gene. The GPC3 gene encodes glypican-3 known as a regulator of cell proliferation and a highly specific HCC tumor marker. GPC3 mutations are inherited as an X-linked recessive trait and only males manifest this condition. The number of C-allele carriers among HCC patients was 1.5 higher than that among HCV patients without HCC. We found that chronic HCV patients carrying the C-allele are 2.7 times more likely to develop HCC than G-allele carriers (p = 0.0095). Conclusion. We found a SNP in the GPC3 gene, which C-allele was associated with an increased risk of HCC in Yakut males with chronic HCV. This genetic marker can be used for personalized prognosis of the disease course and as a predictor of HCC development in patients with liver cirrhosis.
