Abstract

Context: Cervical Cancer (CC) ranks as one of the most common types of malignant tumors affecting women. CDDO-Me is derived from oleanolic acid, a pentacyclic triterpenoid obtained by chemical structural modification, which has been shown anti-tumor effects.

Results: CC cell proliferation was decreased by CDDO-Me both in vitro and in vivo. Mechanistically, CDDO-Me led to a reduction of intracellular mitochondrial volume and crista, or an increase of membrane density. The levels of ROS, Fe2+, MDA were increased while GSH was decreased. Meanwhile, the levels of protein expression of GPX4, Nrf2, NQO1 and FTH1 were observably inhibited by CDDO-Me. Specifically, Ferroptosis triggered by CDDO-Me was reverted by DFO. It has been demonstrated that CDDO-Me-induced Apoptosis and Ferroptosis in CC cells is contingent upon the PI3K/AKT-mediated Nrf2/NQO1 pathway.

Conclusions: CDDO-Me induces CC cell lines Apoptosis and Ferroptosis through the PI3K/Nrf2 signaling pathway, for exerting anti-proliferation effects.
