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.
Insights

Purpose of the Study:
- To investigate the anti-cancer effects of dioscin on human endometrial cancer Ishikawa cells.
- To elucidate the molecular mechanisms underlying dioscin's action.
- To assess dioscin's potential in endometrial cancer prevention and treatment.
Main Methods:
- Cell proliferation assays to determine the half-maximal inhibitory concentration (IC50).
- Cell cycle analysis to identify cell cycle arrest.
- Apoptosis assays including mitochondrial pathway and death receptor pathway analysis.
- Western blotting to assess protein expression levels.
Main Results:
- Dioscin significantly suppressed Ishikawa cell proliferation with an IC50 of 2.37 μM.
- Dioscin induced G0/G1 cell cycle arrest by up-regulating p16, p21, p27 and down-regulating Cyclin A/D/E, CDK2/4/6.
- Dioscin promoted apoptosis via the mitochondrial pathway (Bcl family proteins, ROS, Caspase 9/3, mitochondrial membrane permeability) and the death receptor pathway (Fas, TNF-R1, Caspase 8).
Conclusions:
- Dioscin demonstrates significant anti-cancer effects against human endometrial cancer cells.
- Dioscin induces apoptosis through both intrinsic (mitochondrial) and extrinsic (death receptor) pathways.
- Dioscin holds potential as a therapeutic agent for endometrial cancer prevention and treatment.
