PARP Inhibitors for Recurrent Ovarian Carcinoma: Current Treatment Options and Future Perspectives.
More than simply a promising management option, PARP inhibitors can be regarded as a milestone in the development of personalised treatment of recurrent ovarian carcinoma. Their mechanism of action, known as "synthetic lethality", is dependent on functional differences of the DNA repair mechanisms of healthy cells and tumour cells; cells that repair DNA damage less efficiently are particularly ...
متن کاملThe status of poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors in ovarian cancer, part 2: extending the scope beyond olaparib and BRCA1/2 mutations.
Poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors have shown clinical activity in epithelial ovarian cancer, leading both the US Food and Drug Administration (FDA) and the European Medicines Agency to approve olaparib for tumors characterized by BRCA1 and BRCA2 mutations. However, it is becoming increasingly evident that tumors that share molecular features with BRCA-mutant tumors...
متن کاملPARP inhibition in epithelial ovarian cancer: high hopes undergo a reality check.
The treatment strategy of poly(ADP-ribose) polymerase (PARP) inhibition capitalizes on the inherent defect in homologous recombination that occurs in BRCA-deficient tumors by inhibiting the alternative DNA repair pathway involving base excision repair. Although PARP inhibitors were initially considered a potential treatment specifically for tumors with germline BRCA mutations, evidence of frequ...
متن کاملPARP Inhibitors for Cancer Therapy
Rucaparib is an inhibitor of nuclear poly (ADP-ribose) polymerases (inhibition of PARP-1 > PARP-2 > PARP-3), following a similar drug, Olaparib. It disrupts DNA repair and replication pathways (and possibly transcription), leading to selective killing of cancer cells with BRCA1/2 mutations. Rucaparib is approved for recurrent ovarian cancers with germline or somatic mutations in BRCA1/2.
متن کاملThe Emerging Role of PARP Inhibitors in the Treatment of Epithelial Ovarian Cancer
Poly(ADP-ribose) polymerase-1 (PARP-1) is an important novel target in cancer therapy. This enzyme is essential in the repair of single-stranded breaks in DNA via the base excision repair pathway. Drugs which inhibit PARP are emerging as a promising new class of anticancer agents particularly effective against tumors which have lost homologous recombination (HR) through loss of functional BRCA1...
متن کاملPARP inhibitors
Poly (ADP-ribose) polymerases, abbreviated as PARPs, are a group of familiar proteins that play a central role in DNA repair employing the base excision repair (BER) pathway. There about 17 proteins in this family out of which the primary nuclear PARPs are PARP-1, PARP-2, PARP-3, and tankyrases 1 and 2 (PARP-5a and -5b) .The PARP family members are known to engage in a wide range of cellular ac...
