Objective To study the adiponectin mRNA expression in subcutaneous and omental adipose tissues of type 2 diabetes and their relation with blood adiponectin, body weight index, waist hip ratio and insulin sensitivity. Methods The adiponectin mRNA expression level in adipose tissue of 22 cases with type 2 diabetes and 26 cases of non diabetes controls was assayed by real time fluorescence quantitative RT PCR. The level of plasma adiponectin was measured with ELISA kit. Results The adiponectin mRNA expression in omental adipose tissue was significantly decreased in patients with type 2 diabetes than that in non diabetes controls (P
