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 … WebAlong these lines, ferroptosis is a promising pathway to overcoming therapy resistance of cancer cells. It is therefore of utmost importance to understand the cellular signalling pathways and the molecular mechanisms underlying ferroptosis regulation, including context-specific effects mediated by the neighbouring cells through cell–cell ...
