PARP inhibitors (PARPi) are used as a first-line treatment option for cancers with BRCA1/2 mutations, yet a significant number of patients show a limited response to these agents. In the present study, Lei and colleagues demonstrate that PARPi promote increased ferroptosis sensitivity and this can be exploited therapeutically to improve the response to PARPi, marking an important therapeutic concept to exploit ferroptosis-based strategies in clinical settings.
