Abstract

Ferroptosis, a novel form of programmed cell death, is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases, including Cancer. Stimulating Ferroptosis in Cancer cells may be a potential strategy for Cancer therapy. Therefore, ferroptosis-inducing drugs are attracting more attention for Cancer treatment. Here, we showed that erianin, a natural product isolated from Dendrobium chrysotoxum Lindl, exerted its Anticancer activity by inducing cell death and inhibiting cell migration in lung Cancer cells. Subsequently, we demonstrated for the first time that erianin induced ferroptotic cell death in lung Cancer cells, which was accompanied by ROS accumulation, lipid peroxidation, and GSH depletion. The Ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK, CQ, or necrostatin-1 rescued erianin-induced cell death, indicating that Ferroptosis contributed to erianin-induced cell death. Furthermore, we demonstrated that Ca2+/CaM signaling was a critical mediator of erianin-induced Ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing Ferroptosis. Taken together, our data suggest that the natural product erianin exerts its Anticancer effects by inducing Ca2+/CaM-dependent Ferroptosis and inhibiting cell migration, and erianin will hopefully serve as a prospective compound for lung Cancer treatment.
