Recently, Minami et al. found that loss of CDKN2A expression remodels the lipidome of glioblastoma cells, and patient-derived CDKN2A-deficient glioblastoma cells have higher levels of lipid peroxidation, thereby sensitizing the cells to ferroptosis in response to GPX4 inhibition.281 These results suggest potential new therapeutic strategies in which targeting cellular lipidome remodeling can induce ferroptosis in glioblastoma cells, particularly in cells lacking CDKN2A expression. This evidence concerns the gene CDKN2A and glioblastoma.
