Increasing studies suggest that microRNAs, anew group of small non-coding molecules, regulate theexpression of their target genes and play some roles in cancers. Thus, it is hypothesized that the genetic variants ofmicroRNAs could contribute to the susceptibility to cancers. In this study, the association between rs67106263 in microRNA-3144 and the risk of hepatocellular carcinoma (HCC)was explored in a large-scaled case–control population basedon MassARRAY technology. It was discovered that comparedwith the carriers of wide-type GG genotype and heterozygoteGA genotype of microRNA-3144, thesignificantly increased risk of HCC was observed in thesubjects with the homozygote variant AA (adjusted oddsratio = 1.285, 95 % confidence interval = 1.004–1.643,P = 0.046). Additionally, the variant was also associatedwith the expression of alpha fetoprotein (AFP), which is thediagnostic marker for HCC. Our findings suggest for the firsttime that rs67106263 may play some roles in the risk of HCC,expecting future molecular researches to elucidate the possiblemechanisms behind these results.
