Gpx4 knockout cancer
WebUsing genetic screens, we compared metabolic genes essential for proliferation upon inhibition of cystine uptake or glutathione peroxidase-4 (GPX4). Interestingly, very few genes were commonly required under both conditions, suggesting that cystine limitation and GPX4 inhibition may impair proliferation via distinct mechanisms. WebGPx4 deletion reduces keratinocyte adhesion in culture and increases lipid peroxidation and cyclooxygenase-2 (COX-2) levels in cultured keratinocytes and whole skin. Feeding a COX-2 inhibitor to nursing mothers partially prevents development of the abnormal skin phenotype in knockout pups.
