Next, we examined the expression of acyl-CoA synthetase long-chain family member 4 (ACSL4), arachidonate 5-lipoxygenase (ALOX5), and arachidonate 15-lipoxygenase (ALOX15), which are implicated in lipid peroxidation, a major cause of ferroptosis in carcinoma cells. This evidence concerns the gene ACSL4 and carcinoma.
