Abstract
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.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
