  • Current researches on PARP inhibitors and its treatment of germline BRCA mutated breast cancer

    ObjectiveTo summarize functions and mechanisms of poly ADP-ribose polymerase (PARP) inhibitors and its application in germline BRCA mutated breast cancer.MethodThe literatures about the PARP inhibitors and their applications in the treatment of germline BRCA mutated breast cancer at home and abroad in recent years were collected to make a review.ResultsAs a DNA repair enzyme, the PARP played an important role in the DNA repair pathway. Based on this mechanism, the PARP inhibitors had been developed and widely used in the clinic. On the other hand, the previous studies had shown that the PARP inhibitors marked the synthetic lethal effect in the cancers with homologous recombination deficiency mechanism. By inhibiting the PARP activity in the tumor cells with BRCA mutation, all the DNA damage repair pathways were blocked, which could induce the cell apoptosis or increase the sensitivity of tumor cells to chemoradiotherapy, resulting in the cell death.ConclusionIn patients with germline BRCA mutated breast cancer, PARP inhibitors can selectively kill breast cancer cells and show a high potential for individualized treatment.
