Bajrami, Walker et al. investigated the synthetic lethality between BRCA gene defects and inhibition of two sirtuin genes, SIRT1 or SIRT6, which was found to be associated with replication stress and increased PARylation. The authors demonstrated that the SIRT/BRCA1 synthetic lethality was reversed by genetic ablation of PARP1 or HPF1.
