Ferroptosis meets inflammation: A new frontier in cancer therapy

Abstract

Ferroptosis, an iron-dependent form of regulated cell death driven by lipid peroxidation, has emerged as a critical player in cancer pathogenesis. Concurrently, inflammation, a key biological response to tissue injury or infection, significantly influences cancer development and progression. The interplay between ferroptosis and inflammation represents a promising yet underexplored area of research. This review synthesizes recent advances in understanding the molecular mechanisms governing their interaction, emphasizing how ferroptosis triggers inflammatory responses and how inflammatory mediators, such as TNF-α, regulate ferroptosis through iron metabolism and lipid peroxidation pathways. Key molecular targets within the ferroptosis-inflammation axis, including GPX4, ACSL4, and the NF-κB signaling pathway, offer therapeutic potential for cancer treatment. By modulating these targets, it may be possible to enhance ferroptosis and fine-tune inflammatory responses, thereby improving therapeutic outcomes. Additionally, this review explores the broader implications of targeting the ferroptosis-inflammation interplay in disease treatment, highlighting opportunities for developing innovative strategies to combat cancer. By bridging the gap in current knowledge, this review provides a comprehensive resource for researchers and clinicians, offering insights into the therapeutic potential of this intricate biological relationship.
