Targeting Hsp70 triggers ferroptosis: a novel anti-cancer mechanism of a marine natural product in prostate cancer.

ABSTRACT: Prostate cancer (PCa) remains one of the most common malignant tumors among men worldwide, typically relying on the androgen receptor (AR) signaling pathway. Inducing ferroptosis, a novel form of iron-dependent cell death, represents a promising strategy; however, its regulation by AR signaling is complex. The molecular chaperone heat shock protein 70 (HSP70) is critical for AR stability and function, yet its role as a therapeutic target in this context is underexplored. The anti-proliferative effect of the compound nidurufin (Nid) was assessed across PCa cell lines using MTT, clonogenic, and 3D spheroid assays. Ferroptosis was evaluated by transmission electron microscopy, reactive oxygen species (ROS) detection, and lipid peroxidation analysis. Mechanistic insights were gained through We
