Abstract:
Objective To probe the new mechanism of simvastatin on high-fat diet-induced kidney dam-age. Methods Female SD rats were subjected to a standard control diet(SCD)or high-fat diet(HFD)for 20 weeks,then the HFD group was randomly divided into HFD group and HFD group with simvastatin treatment (HFD+ST,10mg·kg-1·d-1 )for another 8 weeks. The expression of adiponectin,adiponectin receptors R1 and R2, Adenosine 5′-monophosphate(AMP)-activated protein kinase(AMPK),peroxisome proliferator-activated receptorα(PPARα),glucose regulated protein 78(GRP78)and GADD153(CHOP)in kidney were assessed respective-ly. Results Body weight and serum lipid levels in HFD group significantly increased ,expression of adiponectin and its receptors significantly down-regulated. Phosphorylation of AMPKα and PPARα expression decreased,and expression of GRP78 and CHOP up-regulated significantly. Above indexes in simvastatin treatment groups improved significantly. Conclusion Simvastatin can improve high-fat induced kidney damages ,probably by increasing expression of adiponectin and its receptors ,decreasing endoplasmic reticulum stress.
