Lobaplatin inhibits growth of gastric cancer cells by inducing apoptosis

AIM:To assess the anti-cancer effect of lobaplatin on human gastric cancer cells,and to explore the underlying molecular mechanisms.METHODS:The human gastric cancer cell lines MKN-28,AGS and MKN-45 were used.The cytotoxicity of lobaplatin was detected using an MTS cell proliferation assay.Flow cytometry was used to detect cell apoptosis using Annexin V-FITC Apoptosis Detection Kit.The expression of apoptosis-regulated genes was examined at the protein level using Western blot.RESULTS:Lobaplatin inhibited the proliferation of human gastric cancer cells and induced apoptosis,which may be associated with the up-regulation of Bax expression,poly(ADP-ribose)polymerase(PARP)cleavage,p53 expression and the reduction of Bcl-2 expression.CONCLUSION:The cytotoxicity of lobaplatin may be due to its ability of inducing apoptosis of gastric cancer cells,which would support the potential use of lobaplatin for the therapy of gastric cancer.
