Abstract:
Objective To elucidate the association of genetic polymorphisms of key molecules in JAK/STAT signaling pathway with susceptibility of hepatocellular carcinoma (HCC).Methods A total of 367 HCC patients and 367 healthy controls were recruited in this sex- and age-matched case-control study.Genetic polymorphisms of IL-6 (rs1800796,-572C>G),STAT3 (rs744166,+ 26312T>C; rs3816769,+ 42240T>C; rs6503695,+ 40980T>C),EGFR (rs11543848,+ 142530A>G),and mTOR (rs7211818,+ 170278A>G; rs9674559,+ 196983A>G; rs11653499,+65678G>A) were genotyped using a mass spectrometry method.Odds ratio (OR) and 95% confidence interval (CI) were calculated.Results Genotype frequency of the 8 polymorphisms of IL-6,STAT3,EGFR,and mTOR were not significantly different between the patients with HCC and the controls.When stratified by sex,the female subjects who carried STAT3 +26312CC,+ 42240CC,or + 40980CC had a decreased risk of HCC when compared to those who carried TT allele (OR=0.192,95%CI:0.047-0.784; OR=0.180,95%CI:0.045-0.725;OR=0.198,95% CI:0.049-0.806,respectively).When compared with AA genotype on the site of EGFR + 142530,the (AG+ GG) genotype reduced the risk of HCC in women (OR=0.422,95%CI:0.179-0.994).Conclusion The polymorphisms of IL-6 (rs1800796) and mTOR (rs7211818,rs9674559,and rs11653499) were not associated with the HCC susceptibility.Those carrying CC allele in three loci (rs744166,rs3816769,and rs6503695) of STAT3 and (AG + GG) in rs11543848 of EGFR had a decreased risk of HCC in women.However,these results need to be validated using larger sample size.
