ABSTRACT
AIM:
To investigate the protection mechanisms of rosiglitazone on diabetic nephropathy.METHODS:
Rat mesangial cells(MC) were incubated in media containing 5.5 mmol/L normal control glucose,25 mmol/L high concentration glucose,25 mmol/L glucose +20 ?mol/L rosiglitazone maleate.Cells proliferation were assessed by CCK-8.Synthesis of fibronectin(FN),type Ⅳ collagen(Col-Ⅳ),transforming growth factor-?1(TGF-?1) and matrix metalloproteinase inhibitor-1(TIMP-1) in supernatant were determined by ELISA method,the activities of matrix metalloproteinase-2,9(MMP-2,9) in supernatant were determined by gelatinase zymography.RESULTS:
Compared with control group,MC cultured with high concentration glucose showed a high growth rate and increased synthesis of Col-Ⅳand FN,decreased the activities of MMP-2 and MMP-9,and increased secretion of TGF-?1 and TIMP-1.Compared with high glucose group,these changes could be reversed by rosiglitazone intervention.CONCLUSION:
Rosiglitazone could inhibit high concentration glucose-induced proliferation of mesangial cells,decrease synthesis of extracellular matrix,and increase degradation of extracellular matrix.
