ABSTRACT
Objective:
To investigate the effect of Tangshentang on the expression of LOX-1 and secretion of TGF-?1,FN,ColⅣ in cultured rat masengial cells(RMCs) induced by ox-LDL and to explore its molecular mechanism of preventing and treating diabetic nephropathy.Methods:
The cultured RMCs were divided into control group,ox-LDL group,Tangshentang group(respectively high,medium and low group)and rosiglitazone group.The mRNA expression was tested by RT-PCR.Synthesis of TGF-?1,FN,ColⅣ in cultured RMCs were determined by ELISA methods.Results:
Tangshentang drug serum significantly attenuated up-regulation of TGF-?1,LOX-1 mRNA expression and synthesis of TGF-?1,FN,ColⅣ in a dose-dependent manner,with the peak at middle concentration,in RMCs stimulated by ox-LDL(50?g/ml).Conclusion:
Tangshentang drug serum may protect kidney from injury by ox-LDL via the decreased expression of LOX-1 to reduce the uptake of ox-LDL and subsequently inhibiting TGF-?1 secretion,as well as the deposition of FN,ColⅣ.
