PCNA–RECQL5–RPRD1B recruit repair components to stressed replication forks to promote survival of BRCA1-deficient cancer cells
Abstract Given their defect in homologous recombination, BRCA1-deficient cancers use polymerase theta (POLQ) microhomology-mediated end joining (MMEJ) for repair of stressed replication forks. We found that BRCA1-deficient cells repress microRNA (miR) 4485-3p, and reconstituting expression of this miR resulted in the d...
