Abstract

The present study emphasized on the anti-cancerous effects of dioscin and its underlying molecular mechanism in human endometrial cancer Ishikawa cells. Dioscin significantly suppressed the proliferation of Ishikawa cells at IC₅₀ of 2.37 μM. Besides, dioscin could inhibit the proliferation of Ishikawa cells by blocking the G0/G1 cell cycle through up-regulation of p16, p21, and p27 and down-regulation of cycle-cellular protein (Cyclin A/D/E) and cyclin-dependent kinase (CDK2/4/6). Also, it promoted apoptosis through the mitochondrial pathway, including the regulation of Bcl family proteins, the increase of ROS levels, the activation of caspases (Caspase 9/3), and the decrease of mitochondrial membrane permeability. Whereas dioscin also effectively activated the marker genes and proteins (Fas, TNF-R1, and Caspase 8) related to the death receptor-mediated pathway which confirmed the involvement of both the pathways for dioscin-induced apoptosis. The current results demonstrated that dioscin possessed potential health benefits with respect to endometrial cancer prevention and treatment.
