Ferroptosis: a regulated cell death nexus linking metabolism, redox biology and disease

Abstract: Dr. Stockwell will describe the discovery of ferroptosis, a form of regulated cell death characterized by the iron-dependent accumulation of lethal lipid hydroperoxides.  Current data suggest that ferroptosis is an ancient vulnerability caused by the evolution of cells with polyunsaturated fatty acids in membranes, and that cells have developed complex systems that exploit and defend against this vulnerability. The sensitivity to ferroptosis is dependent on amino acid, iron and polyunsaturated fatty acid metabolism, and the biosynthesis of glutathione, phospholipids, NADPH and coenzyme Q10. Ferroptosis is implicated in the pathological cell death associated with degenerative diseases (e.g. Huntington’s Disease), intracerebral hemorrhage, traumatic brain injury, ischemia-reperfusion injury, and kidney degeneration and may be harnessed for cancer therapy. Mechanisms and therapeutic applications will be described.

En savoir plus

Brent R. Stockwell, Ph.D. is a Professor at Columbia University in the Departments of Biological Sciences and Chemistry. His research involves the discovery of precision medicines that can be used to understand and treat cancer and neurodegeneration, with a focus on mechanisms governing cell death. These interdisciplinary investigations have led to new methods of small molecule drug discovery, and the discovery of drug candidates that act through a new form of cell death. Professor Stockwell has received numerous awards, including a Burroughs Wellcome Fund Career Award at the Scientific Interface, a Beckman Young Investigator Award, an HHMI Early Career Scientist Award, the BioAccelerate NYC Prize, the Lenfest Distinguished Columbia Faculty Award and the Great Teacher of Columbia College Award from the Society of Columbia Graduates. He has trained >100 students, technicians and postdoctoral scientists, published >100 scientific articles, been awarded 14 US patents, and received 42 research grants for >$30 million. He founded the biotechnology companies CombinatoRx Incorporated, Solaris Therapeutics and Kyras Therapeutics, and is the author of The Quest for the Cure: The Science and Stories Behind the Next Generation of Medicines.
