Synthetic Lethality and Cancer Therapy: Lessons Learned from the …
WebFeb 28, 2024 · The potency of PARP 1/2 inhibitors in BRCA-deficient cells arises from a synthetic lethality, where the combination of multiple genomic alterations result in cellular death . In turn, SSBs result in replication fork stalling and collapse that result in the formation of double strand breaks during DNA replication ( 26 , 28 ). WebApr 7, 2024 · The first PARP inhibitors approved for clinical use employed the synthetic lethality strategy to treat breast and ovarian cancers caused by BRCA mutations (10). Most of the current PARP-1 inhibitors work by binding to the catalytic domain of PARP-1, inhibiting the addition of PAR chains to substrates, and trapping PARP-1 at the site of … bauhaus ring kamera
