摘要
Astragaloside IV (AS#IV) has previously demonstrated antitumoractivity. We investigated the effect and mechanisms of AS#IV in relation to epithelial-mesenchymal transition (EMT), viainterference with the Wnt/beta-catenin signaling pathway in gliomaU251 cells. Induction of glioma U251 cells by transforming growthfactor (TGF)#beta 1 activated EMT, including switching E#cadherin toN-cadherin and altering the expression of Wnt/beta-catenin signalingpathway components such as vimentin, beta-catenin, and cyclin-D1.AS-IV inhibited the viability, invasion, and migration of TGF-beta 1-induced glioma U251 cells. AS-IV also interfered with the TGF#beta 1-induced Wnt/beta-catenin signaling pathway in glioma U251 cells.These findings indicate that AS#IV prohibits TGF#beta 1-induced EMTby disrupting the Wnt/beta-catenin pathway in glioma U251 cells. AS#IV may thus be a potential candidate agent for treating glioma andother central nervous system tumors.
