Exploring Ferroptosis-Inducing Therapies for Cancer Treatment: Challenges and Opportunities

Abstract Conventional cancer therapies typically aim to eliminate tumor cells by inducing cell death. The emergence of resistance to these standard treatments has spurred a shift in focus toward exploring alternative cell death pathways beyond apoptosis. Ferroptosis—an iron-dependent regulated cell death triggered by lipid peroxide accumulation—has gained prominence in cancer research in recent years. Ferroptosis-inducing therapies hold promise for overcoming resistance encountered with conventional treatments. However, challenges, including the lack of distinctive ferroptosis markers and the intricate role of ferroptosis within the tumor microenvironment, currently hinder the clinical translation of these therapies. This perspective article critically outlines these hurdles and highlights unexplored opportunities in ferroptosis research, aiming to refine its therapeutic utilization in combating cancer.
