Outline of Final Research Achievements

Sorafenib is a multi-kinase inhibitor for hepatocellular carcinoma. To address whether cytokine-mediated signaling is involved in the drug resistance, hepatoma cells were treated with sorafenib in the presence of several cytokines/growth factors. Obtained results showed that the effect of sorafenib on cell growth was significantly inhibited by TGF-beta. When TGF-beta-treated cells were treated with sorafenib and valproic acid, apoptotic cell numbers were increased as compared with those treated with sorafenib alone. Collectively, combination treatment of valproic acid and sorafenib might improve the efficacy of sorafenib.
