Erucic Acid, Derived by Lactobacillus Crispatus, Induces Ferroptosis in Cervical Cancer Organoids Through the PPAR-δ Signaling Pathway.

ABSTRACT: The microbiome present throughout the human body serves a variety of functions. In this study, 16S rRNA sequencing is employed to uncover differences in the abundance of Lactobacillus within the vaginal microbiota between individuals with cervical cancer and those with healthy cervixes. The research further identifies that the metabolite of Lactobacillus crispatus can induce ferroptosis in cervical cancer cells. This conclusion is reached through targeted bacterial culture, patient-derived organoids (PDO) and single-cell RNA sequencing. Erucic acid, identified as a primary metabolite via untargeted metabolomics, acts as a ligand for PPARδ receptor. It has the capacity to activate PPARδ pathway and subsequently trigger downstream fatty acid oxidation (FAO). Excessive enhancement of FAO can
