Glutamate serves a crucial role in the growth and development of malignant breast cancer cells, with its levels primarily regulated by amino acid transporters, notably SLC1A5 and SLC7A5 (56)

The N-terminal of FSP1 contains myristic acylation domain, which has the function of lipid modification, enriching it in plasma and reducing the sensitivity of cells to ferroptosis ( According to Doll et al. s research, overexpression of apoptosis-inducing factor Mitochondrial Associated 2(AIFM2, also known as FSP1) can reverse ferroptosis induced by GPX4 inhibition, which indicates that FSP1 has nothing to do with the mechanism of GPX4 ( 1.2.3 P62-Keap1-Nrf2 signal transduction pathway Other molecular signal pathways related to ferroptosis, including p62-Keap1-Nrf2 signal transduction pathway, bind to Kelch-like ECH-related protein 1(Keap1) under oxidative stress, and remain inactive through ubiquitination in proteasome, and then release Nrf2 from the coupled Keap1 protein and transfer to the nucleus ( Ferroptosis involves many molecules and signal pathways, and these mechanisms provide a new perspective and strategy for studying cell death and treating diseases related to ferroptosis

This mechanistic distinction is one reason these compounds are sometimes studied together in multi-compound laboratory research designs (each acts on a different pathway, so each provides an independent variable for the research design)
