ACSL4 and neoplasm: Studies showed that marine compounds target key molecules such as glutathione peroxidase 4 (GPX4) and long-chain acyl-CoA synthetase 4 (ACSL4(a)) ACSL4(1) to modulate lipid peroxidation and iron metabolism, inducing ferroptosis in tumor cells and reshaping the tumor microenvironment (TME).
