Association between a Variant in MicroRNA-646 and the Susceptibility to Hepatocellular Carcinoma in a Large-Scale Population

چکیده
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 & Objectives: Gastric cancer is the fourth most common cancer in the world and Ardabil province is in the top ranks in the world. MicroRNAs are non-coding RNA molecules with a length of 18 to 21 nucleotides and due to their regulatory role in post- transcriptional gene expression; single nucleotide polymorphisms (SNPs) could affect their function on target genes regulation. Methods: ...

Background: Several studies investigated the association of ACE I/D polymorphism with the risk and severity of COVID-19 infection. However, the information in each of the published studies is limited, and the results were inconsistent or even contradictory. Accordingly, this meta-analysis evaluated the association between the ACE I/D polymorphism and COVID-19 susceptibility and severity. Metho...
