The chain reaction caused by ROS attacking polyunsaturated fatty acids on cell membranes, resulting in lipid peroxidation accumulation, has been widely recognized by researchers as the primary mechanism of ferroptosis.[60] Thus, we have demonstrated a novel finding: erucic acid, a metabolite of Lactobacillus crispatus, can induce ferroptosis in cervical cancer through the PPAR‐δ pathway. This evidence concerns the gene PPARD and cervical carcinoma.
