Activation of the reverse transsulfuration pathway through NRF2/CBS confers erastin-induced ferroptosis resistance
Ferroptosis is an iron-dependent, lipid peroxide-mediated cell death that may be exploited to selective elimination of damaged and malignant cells. Recent studies have identified that small-molecule erastin specifically inhibits transmembrane cystine–glutamate antiporter system xc−, prevents extracellular cystine import and ultimately causes ferroptosis in certain cancer cells. In this study, we…
