Although the involvement of insulin-like signaling in cancer has been well documented in various types of cancers, the association between the genetic variants in the insulin-like signaling and the development of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) remains unclear. In this study, a total of 498 individuals including 173 HBV related cirrhosis patients, 171 HBV-related HCC patients, and 154 healthy controls were enrolled. Sixteen single nucleotide polymorphisms (SNPs) in IGF1, IGF2, IGF1R and IGF2R have been genotyped by employing SNaPshot assays. We found A/A genotype at rs3743251 of IGF1R was negatively associated with HBV related HCC [odds ratio (OR) = 0.38, 95% confidence interval (CI) = 0.20-0.72, P = 0.037]; A/G genotype decreased the risk of portal vein thrombosis (OR = 0.38, 95%CI = 0.18-0.82, P = 0.01). These results indicate that rs3743251 polymorphism in IGF1R is associated with the susceptibility of HBV-related HCC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
