We conducted a case-control study to evaluate the association of miR-146a rs2910164 (C>G), miR-149 rs2292832 (T>C), miR-196a2 rs11614913 (T>C) and miR-499 rs3746444 (T>C) polymorphisms with the risk of hepatocellular carcinoma. A total of 274 patients with HCC were collected between January 2013 and December 2014. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was taken to determine the polymorphism of miR-146a C>G, miR-149 T>C, miR-196a2 T>C and miR-499 T>C. By comparing with control groups, patients with HCC were more likely to be males (OR=2.01, 95% CI=1.38-2.95), have older age (OR=1.52, 95% CI=1.09-2.13), have a history of alcohol drinking (OR=2.09, 95% CI=1.49-2.93), and be infected with HBV (OR=32.98, 95% CI=19.70-55.46) and HCV (OR=56.26, 95% CI=23.28-152.98) infection. By conditional regression analysis, individuals carrying the TC and CC genotypes of miR-196a2 T>C were found to be associated with an elevated risk of HCC compared to the TT genotype, and the adjusted odds ratio were 1.50 (1.03-2.17) and 2.86 (1.60-5.16), respectively. Moreover, the TC+CC genotype was correlated with an increased risk of HCC (OR=1.69, 95% CI=1.19-2.41) compared to the wide-type genotype. In conclusion, our results suggested that miR-196a2 T>C polymorphism is associated with HCC risk in Chinese population.
我们开展了一项病例对照研究,以评估miR-146a rs2910164(C>G)、miR-149 rs2292832(T>C)、miR-196a2 rs11614913(T>C)和miR-499 rs3746444(T>C)基因多态性与肝细胞癌风险的相关性。2013年1月至2014年12月期间共收集了274例肝细胞癌患者。采用聚合酶链反应-限制性片段长度多态性方法(PCR-RFLP)来确定miR-146a C>G、miR-149 T>C、miR-196a2 T>C和miR-499 T>C的基因多态性。与对照组相比,肝细胞癌患者更可能为男性(比值比=2.01,95%可信区间=1.38 - 2.95)、年龄较大(比值比=1.52,95%可信区间=1.09 - 2.13)、有饮酒史(比值比=2.09,95%可信区间=1.49 - 2.93),以及感染乙肝病毒(比值比=32.98,95%可信区间=19.70 - 55.46)和丙肝病毒(比值比=56.26,95%可信区间=23.28 - 152.98)。通过条件回归分析发现,与TT基因型相比,携带miR-196a2 T>C的TC和CC基因型个体患肝细胞癌的风险升高,校正后的比值比分别为1.50(1.03 - 2.17)和2.86(1.60 - 5.16)。此外,与野生型基因型相比,TC+CC基因型与肝细胞癌风险增加相关(比值比=1.69,95%可信区间=1.19 - 2.41)。总之,我们的结果表明,在中国人群中,miR-196a2 T>C基因多态性与肝细胞癌风险相关。
