ABSTRACT
Objective To investigate the inhibitory effects of trichostatin A(TSA)on bladder cancer cell lines and its synergetic effect with anticancer drugs in treating bladder cancer in vitro and in vivo.Methods The inhibitory effects of TSA on human bladder cancer cell lines in vitro were detected by MTT assay.Hoechst staining was used to observe morphology for apoptotic cells after TSA treatment.Western blot was used to detect expression of acetyl-histone H3 and survivin.In vivo synergetic effects of TSA with anticancer drugs were detected in bladder cancer model rats.Results TSA significantly inhibited growth of bladder cancer cell lines in concentration and time dependent manner.Better results of tumor inhibition have been achieved when it was combined with DDP,MMC and ADM than used alone.After TSA treatment,the survivin expression in bladder cancer cells decreased and acetyl-histone H3 expression increased.Intravesical application of TSA combined with MMC can significantly inhibited tumor growth and progression.Conclusion TSA has direct anti-cancer effect and can enhance the action of several chemotherapy agents markedly.TSA may be an excellent candidate agent for intravesical application to treat bladder cancer.
