Mechanisms of PARP inhibitor resistance in cancer and insights into the DNA damage response

Genome Medicine, 2018
Editorial summary Inhibitors of poly(ADP-ribose) polymerase (PARPi) have entered the clinic for the treatment of patients with cancers that lack homology-directed DNA repair, but drug resistance remains a clinical hurdle.

HPF1 remodels the active site of PARP1 to enable the serine ADP-ribosylation of histones

Nature Communications, 2021
Once DNA breaks occur, poly(ADP-ribose) polymerase 1 (PARP1) ADP-ribosylates itself and other DNA repair factors to initiate the repair process. Here, the authors resolve the crystal structures of mouse and human HPF1, and human HPF1/PARP1 complex ...

PARP-1 regulates DNA repair factor availability. [PDF]

, 2018
PARP-1 holds major functions on chromatin, DNA damage repair and transcriptional regulation, both of which are relevant in the context of cancer. Here, unbiased transcriptional profiling revealed the downstream transcriptional profile of PARP-1 enzymatic

Poly(ADP-ribosyl)ation of p53 In Vitro and In Vivo Modulates Binding to its DNA Consensus Sequence

Neoplasia: An International Journal for Oncology Research, 2001
The tumor-suppresser p53 undergoes extensive poly(ADP-ribosyl)ation early during apoptosis in human osteosarcoma cells, and degradation of poly(ADP-ribose) (PAR) attached to p53 coincides with poly(ADP-ribose)polymerase-1, (PARP-1) cleavage, and ...

PARP1 allows proper telomere replication through TRF1 poly (ADP-ribosyl)ation and helicase recruitment

Communications Biology, 2023
The poly (ADP-ribose) polymerase (PARP1) interacts with the telomere factor TRF1 and loss of PARP1 results in telomere fragility and impairment of helicases -TRF1 complex assembly.

Kynurenine–PARP-1 Link Mediated by MicroRNA 210 May Be Dysregulated in Pulmonary Hypertension

Anatolian Journal of Cardiology, 2022
Background: Dysregulation of microRNAs is associated with pulmonary hypertension. The present study aimed to determine the alterations in microRNA and microRNA expressions and their role in signaling pathways and investigate the relationship with serum ...

Metabolic roles of poly(ADP-ribose) polymerases [PDF]

Seminars in Cell & Developmental Biology, 2017
Poly(ADP-ribosyl)ation (PARylation) is an evolutionarily conserved reaction that had been associated with numerous cellular processes such as DNA repair, protein turnover, inflammatory regulation, aging or metabolic regulation. The metabolic regulatory tasks of poly(ADP-ribose) polymerases (PARPs) are complex, it is based on the regulation of metabolic

Inflammation-induced DNA damage and damage-induced inflammation: a vicious cycle [PDF]

, 2014
Inflammation is the ultimate response to the constant challenges of the immune system by microbes, irritants or injury. The inflammatory cascade initiates with the recognition of microorganism-derived pathogen associated molecular patterns (PAMPs) and ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
