1 The involvement of lipid raft pathway in suppression of TGFbeta-mediated metastasis by tolfenamic acid in hepatocellular carcinoma cells. tolfenamic acid transforming growth factor alpha Mus musculus
2 Herein, we investigated the effect of TA on TGFbeta-mediated pro-metastatic activity and the underlying mechanisms in hepatocellular carcinoma (HCC). tolfenamic acid transforming growth factor alpha Mus musculus
3 As a result, TA suppresses TGFbeta-induced migration and glycolysis in HCC cells, which is accompanied with reduced Smad phosphorylation and subsequent nuclear transcription activity. tolfenamic acid transforming growth factor alpha Mus musculus
4 Mechanistically, TA promotes lipid raft-caveolar internalization pathway of TGFbeta receptor, therefore leading to its rapid turnover. tolfenamic acid transforming growth factor alpha Mus musculus
5 Consistently, TA inhibits constitutively active TGFbeta type I receptor induced Smad phosphorylation and EMT markers, whereas ectopic expression of TGFbeta type II receptor could partially rescue TGFbeta-mediated Smad2 phosphorylation and downstream genes expression in the presence of TA. tolfenamic acid transforming growth factor alpha Mus musculus
6 Our study suggests TA could activate lipid raft pathway and modulate TGFbeta mediated metastasis, implicating the potential application of TA as a modulator of tumor microenvironment in HCC. tolfenamic acid transforming growth factor alpha Mus musculus
