Abstract Ferroptosis is an iron-dependent form of regulated cell death driven by lipid peroxidation. In this study, we identify the transcription factor v-maf musculoaponeurotic fibrosarcoma oncogene homolog F (MAFF) as a key regulator that promotes breast cancer progression while simultaneously sensitizing tumor cells to ferroptosis. Integrated RNA-sequencing and chromatin immunoprecipitation (ChIP)-sequencing revealed that MAFF directly regulates genes involved in iron and fatty acid metabolism.

Abstract Iron is vital to living cells, playing a key role in cellular respiration, DNA synthesis, and various metabolic functions. Importantly, cancer cells have a higher dependency on iron compared to normal cells to support their rapid growth and survival. Due to this fact, tumors are more vulnerable to ferroptosis, an iron-dependent form of regulated cell death. Radiation therapy (RT), a standard treatment for many cancer patients, is known to induce ferroptosis.
