文摘

As a multifunctional cytokine, interleukin-6 (IL-6) plays a key role in chronic inflammation as well as tumor growth and progression of hepatitis B virus (HBV) infection. Recent studies have implicated that single nucleotide polymorphism (SNP) 鈭?72C>G (rs1800796) located within the promoter region of IL-6 gene was associated with susceptibility to several diseases. Here, a case-control study was undertaken to investigate the association between this polymorphism and HBV-related hepatocellular carcinoma (HCC) susceptibility in a Chinese Han population. A total of 900 patients with chronic HBV infection, including 505 HBV-related HCC patients and 395 HBV infected patients without HCC were enrolled, and rs1800796 polymorphism was genotyped by the TaqMan method and DNA sequencing technology. The results indicated no significant association between rs1800796 polymorphism and the risk of HBV-related HCC in all subjects; however, a significant difference was identified in male subjects. Under the dominant model, male subjects with the G allele (CG/GG) have higher susceptibility to HBV-related HCC than those with CC genotype after adjusting confounding factors (P = 0.012, odds ratio [OR] 1.68, 95% confidence interval [95% CI] 1.15-2.42). Our results suggested that rs1800796 polymorphism of IL-6 gene was associated with susceptibility to HBV-related HCC in a male Chinese Han population.
