The redox environment of the cell is currently thought to be extremely important to control either apoptosis or autophagy. This study reported that reactive oxygen species (ROS) and nitric oxide (NO) generations were induced by evodiamine time-dependently; while they acted in synergy to trigger mitochondria-dependent apoptosis by induction of mitochondrial(More)
Previous studies have shown that evodiamine could trigger apoptosis in human malignant melanoma A375-S2 cells within 24 h. To further investigate the biochemical basis of this activity, the roles of reactive oxygen species (ROS) and mitochondrial permeability transition (MPT) were evaluated. Exposure to evodiamine led to a rapid increase in intracellular(More)
A previous study indicated that reactive oxygen species (ROS) and nitric oxide (NO) played pivotal roles in mediating cytotoxicity of evodiamine in human cervix carcinoma HeLa cells. This study suggested that G2/M cell cycle arrest was triggered by ROS/NO productions with regulations of p53, p21, cell division cycle 25C (Cdc25C), Cdc2 and cyclin B1, which(More)
