PARP Goes Transcription
PARP-1, an enzyme that catalyzes the attachment of ADP ribose units to target proteins, plays at least two important roles in transcription regulation. First, PARP-1 modifies histones and creates an anionic poly(ADPribose) matrix that binds histones, thereby promoting the decondensation of higher-order chromatin structures. Second, PARP-1 acts as a component of enhancer/promoter regulatory comp...
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...
متن کاملPARP Inhibitors
Poly (ADP-ribose) polymerase (PARP) is a novel therapeutic target in cancer. Preclinical studies demonstrate that PARP inhibitors selectively kill BRCAdeficient cells and potentiate the effects of DNA-damaging agents. There are several PARP inhibitors in clinical development, including olaparib, iniparib, veliparib, PF01367338, and MK-4827. Phase II studies of single-agent olaparib demonstrate ...
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 and more.
Polyadenosine diphosphate (ADP) ribose polymerase (PARP) lends a panoramic view to the inner mystery of protection of integrity of deoxyribonucleic acid (DNA) in a cell genome. They are a balancing part of an even more dynamic equilibrium of normalcy against daily assaults. PARP finds its companion candidates in other tumor suppressors, with the most prominent and glaring one being breast cance...
