Objective:To explore the effect of berberine on adiponectin gene mRNA expression in 3T3-L1 adipocyte of insulin resistant induced by interleukin-6(IL-6).Method: To build 3T3-L1 adipocyte model of insulin resistant induced by interleukin-6.3T3-L1 adipocytes were exposed to 20 μg · L-1 IL-6 for 48 h,the 3T3-L1 adipocytes with insulin resistant were divided into six groups randomly: normal control groups,model groups,pioglitazone(50 μmol · L-1),and low,middle,hight doses of berberine groups(10,20,50 μmol · L-1...
