- Abstract
- Oridonin, an active diterpenoid isolated fromRabdosia rubescens, has been reported to exhibit anticancer activities in several tumors. The aim of the present study was to investigate the anticancer effects and molecular mechanisms of oridonin in mucoepidermoid carcinoma (MEC). Treatment with oridonin induced the apoptosis of MC-3 and YD-15 cell and inhibited the expression of myeloid cell leukemia-1 (MCL-1) through the regulation of the protein level through post-translational regulation in these cell lines. Oridonin significantly increased the expression level of truncated Bid (t-Bid) as a downstream target of MCL-1 and subsequently decreased the mitochondrial membrane potential. The ectopic expression of MCL-1 protein was sufficient to reverse the induction of apoptosis and the increased t-Bid expression induced by oridonin in both cell lines. Taken together, these results suggest that oridonin exerts an apoptotic effect through the modulation of MCL-1 and t-Bid in human MEC cell lines and may thus be a potential anticancer drug candidate for the treatment of human MEC.
