MMPT, a thiazolidin compound, was identified in our laboratory as a novel antineoplastic agent with a broad spectrum of antitumor activity against many human cancer cells. However, the related mechanism has yet not been revealed. In this study, we investigated the cellular and molecular events underlying the antitumous function of this compound in human lung adenocarcinoma H1792 cells, focusing on the early cytotoxic effect. Treatment of H1792 cancer cells with MMPT (0.1–100 μM for 24–72 h) resulted in a growth inhibition in a dose and time-dependent manner, determined by MTT assay. This effect was accompanied by apoptosis, evidenced by Nucleosome ELISA, H33258 stained assay, and Sub-G1 analysis. Our data showed that MMPT caused activation of caspase-3, caspase-6 and caspase-8, but not caspase-9. The finding that MMPT induced apoptosis through a membrane-mediated mechanism was supported by the up-regulated expression of Fas (CD95/APO-1), and Fas ligand. Overall, our results demonstrated that MMPT induced growth inhibition of H1792 cells through a Fas-mediated and caspase-dependent apoptosis pathway, which suggested that MMPT might be used as a Fas/FasL and caspases promoter to initiate lung cancer cell apoptosis.
