Rsl3 in ferroptosis

WebMar 1, 2024 · Indeed, RSL3 and other small-molecule GPX4 inhibitors can induce ferroptosis in not only cultured cancer cells but also tumor xenografts implanted in mice. Similarly, erastin and other system Xc− inhibitors can deplete intracellular glutathione required for GPX4 function, leading to lipid peroxidation and ferroptosis. WebMar 15, 2024 · Ferroptosis was recognized as a distinct mechanism of nonapoptotic programmed cell death through a small-molecule screen, and erastin and RSL3 were identified as compounds that induce selective lethality in cancer cells that express mutant HRAS (24, 35–38).
