Nuclei were stained with 200 nM 4,6-diamidino-2-phenyl-indole (DAPI) for 5 min
Up to now, powerful genetic tools allowed clarification of the significance, dispensability and potential of cystine transporters for ferroptotic cell death in PDAC and breast cancer ( via xCT ( A high extracellular glutamate concentration was one of the first xCT inhibitors described but a few years later, erastin (standing for eradicator of RAS and small T antigen-expressing cells) was identified by Stockwell's group in RAS-mutated cancer cell lines as inhibitor of xCT transport ( in vitro studies as efficient inducer of ferroptosis in many different cancer types, including breast, PDAC, lymphoma, renal, brain and ovarian cancers ( via transsulfuration pathway is a potential resistance mechanism under cysteine depletion conditions
