WebApr 7, 2024 · Mounting evidence supports the crucial role of ferroptosis in tumor suppression. For example, a strong dependence of cancer cells on GPX4 and system Xc- has been noted in multiple types of cancer, and the inhibition of the system Xc- coding gene SLC7A11 induces ferroptotic cell death and enhances cytotoxicity in therapy-resistant … WebDec 1, 2024 · Recently, it was shown that inhibition of GPX4 renders therapy-resistant cancer cells susceptible to ferroptosis [7], [8]; however, some cancer cells persistently evade this. The present study revealed a mechanism underlying resistance to GPX4 inhibition, which involved p62 expression along with activation of the Nrf2–ARE system. The Keap1 ...
