Abstract: Objective To study the adiponectin mRNA expression in omental adipose tissue of type 2 diabetes. Methods RT-PCR method was used to examine the adiponectin mRNA expression. Fasting levels of BG,TG,TC,HDL-C,LDL-C of all the subjects were checked and their blood pressure,height,weight,waist circumference,hip circumference were measured to calculate BMI,WHR. Results The adiponectin mRNA expression in omental adipose tissue was decreased in diabetes group versus non-diabetes group (P<0.05),and negatively correlated with WC,TG,FBG,WHR(P<0.05). Conclusions Type 2 diabetic patients show lower expression of adiponectin mRNA in omental adipose tissue than that of non-diabetic control.WC,TG,FBG, WHR and course of disease are correlated with adiponectin mRNA expression and insulin resistance
