2015023 Astragaloside IV attenuates renal tubulointerstitial fibrosis by inhibiting p38 MAPK signaling.XU Weijia（徐維佳），et al.Dept Nephrol，Kidney Dis Molec Cell Lab，Renji Hosp，Sch Med，Shanghai jiaotong Univ，Shanghai 200001.Chin J Nephrol，2014；30（10）：770-776.

Ob jectiveTo investigate the effect of astragaloside IV（AS-IV）on renal tubulointerstitial fibrosis and its regulation on p38 MAPK signaling.MethodsIn vivo，UUO modelwith renal tubulointerstitial injury was constructed. Mice in AS-IV group were orally administrated AS-IV 20 mg·kg-1·d-1for 7 days after operation，and mice in other groups were administrated the equal volume vehicle.Bilateral kidneys were collected in 7 and 14 days after operation.Transverse kidney slices were stained with Masson trichrome to evaluate the severity of renal tubule injury.In vitro，normal human renal tubular epithelial cells（HK-2）were stimulated with reombinant TGF-β1（10 ng/mL）and simultaneously treated with different concentrations of AS-IV（0，50，100，200μg/mL）for 24 h.SB203580（10μmol/L）was also utilized to pretreat HK-2 cells for 1 h to inhibit phosphorylation of p38 MAPK signaling.The expression of FN，Col IV，andα-SMA was investigated by western blotting and real-time PCR.The expression of p-p38MAPKswas also observed by Western Blotting.Resu ltsAstragaloside IV morphologically ameliorated renal tubulointerstitial fibrosis.The proteins andmRNA expression of FN，Col IV，α-SMA，and TGF-β1 were also increased significantly in UUO kidney tissues（all P＜0.05），which could be reversed by AS-IV administration（all P＜0.05）.In vitro，the expression of FN，Col IV，andα-SMA were up-regulated by TGF-β1 after stimulating for 24 h（all P＜0.05），which were decreased by AS-IV.The inhibition effects on FN andα-SMA were similar between AS-IV and MAPK inhibitor SB203580.AS-IV inhibited p-p38 MAPK signals both in vivo and in vitro.ConclusionASIV could attenuate renal tubulointerstitial fibrosis induced by UUO and TGF-β1 through reducing FN、Col IV、α-SMA expression in renal tubular cells.Themechanism of AS-IV protective effectmight be associated with inhibition of p38 MAPK phosphorylation.
