Tackling PARP inhibitor resistance
Trends in Cancer, 2021Homologous recombination-deficient (HRD) tumours, including those harbouring mutations in the BRCA genes, are hypersensitive to treatment with inhibitors of poly(ADP-ribose) polymerase (PARPis). Despite high response rates, most HRD cancers ultimately develop resistance to PARPi treatment through reversion mutations or genetic/epigenetic alterations to

The much anticipated results from two phase III studies evaluating the clinical efficacy of poly(ADP-ribose) polymerase (PARP) inhibition in patients with advanced-stage breast cancer harbouring a germline mutation in BRCA1/2 have established new therapeutic opportunities and yet, have left us with several ongoing questions.

PARP inhibitor combination therapy
Critical Reviews in Oncology/Hematology, 2016In 2014, olaparib (Lynparza) became the first PARP (Poly(ADP-ribose) polymerase) inhibitor to be approved for the treatment of cancer. When used as single agents, PARP inhibitors can selectively target tumour cells with BRCA1 or BRCA2 tumour suppressor gene mutations through synthetic lethality.

Poly(ADP-ribose) polymerase (PARP) catalyzes the biochemical conversion of nicotinamide adenine dinucleotide (NAD+) to poly(ADP-ribose) and nicotinamide, which is a weak feedback inhibitor of the enzyme. Early designs of PARP inhibitors were primarily based on mimicking the structure of nicotinamide and resulted in the identification and widespread use

PARP inhibitors for prostate cancer
Seminars in OncologyPoly(ADP-ribose) polymerase (PARP) inhibitors have transformed the treatment landscape for patients with metastatic castration-resistant prostate cancer (mCRPC) and alterations in DNA damage response genes. This has also led to widespread use of genomic testing in all patients with mCRPC.

PARP Inhibitors in Prostate Cancer
Current Treatment Options in Oncology, 2017The genomic landscape of metastatic prostate cancer (mPCa) reveals that up to 90% of patients harbor actionable mutations and >20% have somatic DNA repair gene defects (DRD). This provides the therapeutic rationale of PARP inhibition (PARPi) to achieve "synthetic lethality" in treating this fatal disease. Clinical trials with PARP inhibitors have shown

Mechanisms of PARP Inhibitor Resistance
2023Poly(ADP-ribose) polymerase (PARP) inhibitors (PARPi) represent the first medicines based on the targeting of the DNA damage response (DDR). PARPi have become standard of care for first-line maintenance treatment in ovarian cancer and have also been approved in other cancer indications including breast, pancreatic and prostate.

PARP Inhibitors and Parkinson’s Disease
New England Journal of Medicine, 2019PARP Inhibitors and Parkinson’s Disease A recent study implicates the enzyme poly(adenosine 5′-diphosphate-ribose) polymerase 1 (PARP1) as a mediator of neuronal cell death in Parkinson’s disease.

PARP inhibitor resistance mechanisms and PARP inhibitor derived imaging probes
Expert Review of Anticancer TherapyPoly(ADP-ribose) polymerase 1 (PARP1) inhibition has become a major target in anticancer therapy. While PARP inhibitors (PARPi) are approved for homologous recombination (HR) deficient cancers, therapeutic resistance is a challenge and PARPi are now being investigated in cancers lacking HR deficiencies.

Development of PARP inhibitors in oncology
Expert Opinion on Investigational Drugs, 2008Poly (ADP-ribose) polymerase (PARP) plays a key role in DNA repair mechanisms by detecting and initiating repair after DNA strand breaks. Inhibition of PARP in DNA repair-defective tumors (like those with BRCA1 or BRCA2 mutations) can lead to gross genomic instability and cell death.
