Ferroptosis as a target mechanism in heart and kidney disease.

Ferroptosis is a distinct form of regulated cell death driven by lipid peroxidation and redox imbalance. Since its formal recognition in 2012, ferroptosis has emerged as a central pathway linking metabolic stress and oxidative injury to both physiologic and pathologic processes. Its functions extend from tissue sculpting during embryogenesis and tumor suppression to pathologic contributions in neurodegeneration, cardiovascular disease, liver and kidney injury, cancer, and inflammatory disorders. Despite these advances in our understanding of ferroptosis, critical questions remain regarding its precise regulation, context-specific consequences, and interactions with other cell death pathways. Continued progress in identifying biomarkers, defining context-specific roles, and developing selective modulators will be essential to translate ferroptosis biology into clinical therapies with broad impact. Here, we describe the current state of our understanding of the role of ferroptosis in physiology and its potential as a target mechanism in heart and kidney disease.
