Abstract/OtherAbstract:
Objective To explore the association between rs3758539G-803A and rs10882283T-179G polymorphism of retinol binding protein 4 (RBP4) and rosiglitazone response in Chinese type 2 diabetes mellitus (T2DM) patients. Methods A total of 472 Chinese T2DM patients and 198 healthy subjects were enrolled to identify G-803A and T-179G genotypes using a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. Forty-two T2DM patients with different G-803A or T-179G genotypes were selected to undergo a 12-week rosiglitazone treatment (4 mg/d). Serum fasting plasma glucose (FPG),postprandial plasma glucose (PPG),fasting serum insulin (FINS),glycated hemoglobin (HbAlc),postprandial serum insulin (PINS),triglyceride (TG),low-density lipoprotein-cholesterol (LDL-c),and high-density lipoprotein-cholesterol (HDL-c) were determined before and after the rosiglitazone treatment. Results T2DM patients with RBP4 G-803A GG genotype showed lower TG and LDL-c concentrations compared with that in the GA+AA genotype subjects. T2DM patients with RBP4 T-179G TT genotype showed lower waist-to-hip ratio (WHR),FPG and FINS values compared with that in the TG+GG genotype individuals. Patients with GG genotype of RBP4 G-803A had an enhanced rosiglitazone efficacy on FPG and FINS compared with that in the GA+AA genotype group. Patients with RBP4 T-179G TG+GG genotype showed an enhanced rosiglitazone efficacy on HbAlc level compared with that in the TT genotype group. Conclusion RBP4 G-803A and T-179G polymorphism might be associated with the development of T2DM and affect the therapeutic efficacy of rosignitazone in Chinese T2DM patients.
