This report identifies Cdk1's phosphorylation of BRCA1 as an important regulator of BRCA1's DNA repair function. Cdk1 inhibition renders cancer cells sensitive to PARP inhibition, and the combination treatment can inhibit tumor growth in vivo, expanding the potential application of PARP inhibitors beyond BRCA1-deficient tumors.
