The roads to ferroptosis under homeostatic versus pathological conditions

Mol Cell Oncol. 2021 Oct 6;8(5):1970477. doi: 10.1080/23723556.2021.1970477. eCollection 2021.

Abstract

The calcium-independent phospholipase iPLA2β has been identified as a transcriptional target of the tumor suppressor TP53 (or p53). Unlike GPX4 (glutathione peroxidase 4), iPLA2β is not required for normal homeostasis but critical for ferroptosis during stress responses. Our results implicate iPLA2β as an essential regulator in a noncanonical ferroptosis pathway.

Keywords: Ferroptosis; iPLA2β; lipid peroxidation; p53.
