abstract = {Cell death programs such as apoptosis and ferroptosis are
associated with aberrant redox homeostasis linked to lipid
metabolism and membrane function. Evidence for cross-talk
between these programs is emerging. Here, we show that
cytotoxic stress channels polyunsaturated fatty acids via
lysophospholipid acyltransferase 12 into phospholipids that
become susceptible to peroxidation under additional redox
stress. This reprogramming is associated with altered
acyl-CoA synthetase isoenzyme expression and caused by a
decrease in growth factor receptor tyrosine kinase
(RTK)-phosphatidylinositol-3-kinase signaling, resulting in
suppressed fatty acid biosynthesis, for specific stressors
via impaired Akt-SREBP1 activation. The reduced availability
of de novo synthesized fatty acids favors the channeling of
polyunsaturated fatty acids into phospholipids. Growth
factor withdrawal by serum starvation mimics this phenotype,
whereas RTK ligands counteract it. We conclude that
attenuated RTK signaling during cell death initiation
increases cells' susceptibility to oxidative membrane damage
at the interface of apoptosis and alternative cell death
programs.},
