Little is known about the regulation
of nonapoptotic cell death.
Using massive insertional mutagenesis of haploid KBM7 cells we identified
nine genes involved in small-molecule-induced nonapoptotic cell death,
including mediators of fatty acid metabolism (ACSL4) and lipid remodeling (LPCAT3) in ferroptosis.
One novel compound, CIL56, triggered cell death dependent upon the
rate-limiting de novo lipid synthetic enzyme ACC1.
These results provide insight into the genetic regulation of cell
death and highlight the central role of lipid metabolism in nonapoptotic
cell death.
