Abstract:
Objective:To investigate the effect of asiaticoside on renal fibrosis in chronic renal failure(CRF)rats by regulating the Hippo-YAP associated protein(YAP)signaling pathway.Methods:The CRF rat model was established by gavage of Adenine.They were randomly grouped into model group,low dose asiaticoside group(16 mg/kg),high dose asiaticoside group(32 mg/kg),empty load group,high dose asiaticoside(32 mg/kg)+YAP overexpression group,with 12 rats in each group,another 12 SD rats were taken as the control group by gavage with an equal dose of 0.9%sodium chloride solution,after grouping and treated with asiaticoside,empty plasmid and YAP overexpression plasmid,the renal function indicators such as blood creatinine(Scr),endogenous creatinine clearance rate(Ccr),24-hour urine protein content and renal index were measured;HE staining was applied to detect the pathologi-cal morphology of renal tissue;Masson staining was applied to detect renal tissue fibrosis;kits were applied to determine the levels of TNF-α,C-reactive protein(CRP),malondialdehyde(MDA)and superoxide dismutase(SOD)in kidney tissue and serum;Western blot was applied to detect the expressions of fibronectin(FN),Collagen Ⅲ and Hippo-YAP signal related proteins(YAP1,TAZ)in renal tissue.Results:Compared with control group,the renal tissue of rats in model group showed obvious pathological damage symp-toms,the Scr and Ccr levels,24-hour urine protein content,renal index,renal tissue CVF,renal tissue and serum TNF-α,CRP and MDA levels,renal tissue FN,Collagen Ⅲ,YAP1 and TAZ protein expression were obviously increased(P<0.05),the levels of SOD in renal tissue and serum were obviously reduced(P<0.05).Compared with model group,the pathological damage symptoms of kidney tissue in the low and high dose asiaticoside groups were improved,the Scr and Ccr levels,24-hour urine protein content,renal index,renal tissue CVF,renal tissue and serum TNF-α,CRP and MDA levels,renal tissue FN,Collagen Ⅲ,YAP1 and TAZ protein ex-pression were all reduced(P<0.05),the levels of SOD in renal tissue and serum were increased(P<0.05);the pathological damage symptoms of kidney tissue in the high-dose asiaticoside group were further improved compared to the low-dose asiaticoside group,the Scr and Ccr levels,24-hour urine protein content,renal index,renal tissue CVF,renal tissue and serum TNF-α,CRP and MDA lev-els,renal tissue FN,Collagen Ⅲ,YAP1 and TAZ protein expression were further reduced(P<0.05),the levels of SOD in renal tis-sue and serum were further increased(P<0.05);there was no obvious change in all indicators of the unloaded group(P>0.05).Com-pared with the high-dose asiaticoside group,the kidney tissue pathological damage symptoms of rats in the high-dose asiaticoside+YAP overexpression group worsened,the Scr and Ccr levels,24-hour urine protein content,renal index,renal tissue CVF,renal tis-sue and serum TNF-α,CRP and MDA levels,renal tissue FN,Collagen Ⅲ,YAP1 and TAZ protein expression were increased(P<0.05),the levels of SOD in renal tissue and serum were decreased(P<0.05).Conclusion:Asiaticoside can inhibit inflammation and oxidative stress response in CRF rats by reducing Hippo-YAP signaling activity,thereby reducing renal tissue damage and fibrosis,and promoting the recovery of renal function.
