Association of polymorphisms of adiponectin gene promoter-11377C/G, glutathione peroxidase-1 gene C594T, and cigarette smoking in nonalcoholic fatty liver disease.

Background: The number of studies on adiponectin, GPx-1 gene polymorphisms, and nonalcoholic fatty liver disease (NAFLD) susceptibility is increasing, but none have investigated the effect of cigarette smoking in combination with the gene polymorphisms on the susceptibility to NAFLD. In order to understand the distribution of adiponectin and GPx-1 in the local population, to explore the possible association of cigarette smoking with adiponectin and GPx-1 gene polymorphisms in the pathogenesis of NAFLD, we conducted this research, examining the distribution of polymorphisms of adiponectin and GPx-1 in NAFLD patients and healthy controls, analyzing the association between these polymorphisms and cigarette smoking.

Interaction of Polymorphisms of Resistin Gene Promoter -420C/G, Glutathione Peroxidase -1 Gene Pro198Leu and Cigarette Smoking in Nonalcoholic Fatty Liver Disease.

Background: Many studies have suggested that cigarette smoking and polymorphisms of resistin and glutathione peroxidase-1 (GPx-1) genes are closely correlated with the pathogenesis of nonalcoholic fatty liver disease (NAFLD). However, few reports have investigated these associations with respect to NAFLD susceptibility. We, therefore, examined the distribution of polymorphisms in GPx-1 and resistin genes in NAFLD patients and healthy controls and analyzed the relationship between these polymorphisms and smoking status.
