Dual targeting of BRAF and MAPK signaling in the BRAF v600E mutant colorectal cancer patients has shown limited efficacy in clinical studies. Here, the authors identify PLK1 inhibition as synthetic lethal with dual BRAF and EGFR inhibition due to loss of ferroptosis inhibition via a PLK1-CBX8-GPX4 signaling axis in preclinical models of colorectal cancer.
