content and reactive oxygen species production were increased and protein levels of SLC7A11 and GPX4 were decreased by eriodictyol. Besides, eriodictyol reduced the ratio of JC-1 fluorescence ratio, glutathione and malondialdehyde contents but elevated Cytochrome C level. Nrf2 phosphorylation were obviously downregulated by eriodictyol. Finally, eriodictyol suppressed tumor growth, aggravated mitochondrial dysfunction and downregulated Nrf2 expression in tumor tissue in mice. Eriodictyol regulated ferroptosis, mitochondrial dysfunction and cell viability via Nrf2/HO-1/NQO1 signaling pathway in ovarian cancer.
