Description:
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.
