DNA is damaged thousands of times during each cell cycle, and that damage must be repaired, including in cancer cells. Otherwise the cells may die due to this damage. Chemotherapy and radiation therapy attempt to kill cancer cells by inducing high levels of DNA damage. By inhibiting PARP1 DNA repair, the effectiveness of these therapies can be increased. BRCA1, BRCA2 and PALB2 are proteins that are important for the repair of double-strand DNA bre… WebWe describe the mechanism of action of PARPi, key clinical trials which resulted in the FDA approval of olaparib, and current guidelines and administration recommendations.
