Molecular mechanism of poly(ADP-ribosyl)ation by PARP1 and identification of lysine residues as ADP-ribose acceptor sites [PDF]

, 2017
Poly(ADP-ribose) polymerase 1 (PARP1) synthesizes poly(ADP-ribose) (PAR) using nicotinamide adenine dinucleotide (NAD) as a substrate. Despite intensive research on the cellular functions of PARP1, the molecular mechanism of PAR formation has not been ...

ID3 deficiency alters chromatin accessibility at DSB sites and enhances vulnerability to HDAC inhibition

International Journal of Cancer, EarlyView.
What's New? Errors in DNA double‐strand break (DSB) repair can lead to mutations, chromosomal instability, and ultimately cancer. Inhibitor of DNA‐binding 3 (ID3), a transcriptional repressor, is crucial to promoting DSB repair and helping maintain genome stability. Here, the authors investigated ID3 regulation of DNA repair via chromatin accessibility

Regulation of chromatin structure by poly(ADP-ribosyl)ation

Frontiers in Genetics, 2012
The interaction of DNA with proteins in the context of chromatin has to be tightly regulated to achieve so different tasks as packaging, transcription, replication and repair.

Ubiquitination accomplished: E1 and E2 enzymes were not necessary [PDF]

, 2016
Qiu et al. (2016) show that a mono-ADP-ribosyltransferase, SdeA, from Legionella pneumophila catalyzes ADP-ribosylation of ubiquitin, allowing SdeA to modify substrate with ubiquitin in the absence of E1 and E2 ...

Metabolome analysis identified exogenous cholesterol within lipid rafts that activate the Akt/mTOR signaling pathway in epithelial ovarian cancer

International Journal of Cancer, EarlyView.
What's New? Epithelial ovarian cancer (EOC) is a severe malignancy with few effective treatment options. While the mechanisms remain unclear, changes in lipid metabolism may fuel tumor growth and EOC progression, offering a possible path for new treatments.

PARP1 and PARG Are the Draft Horses for Polycomb-Trithorax Chromatin Regulator Machinery

Biomolecules
During tissue differentiation, gene expression patterns are committed to the epigenetic cellular memory machinery, including Polycomb and Trithorax groups (PcG and TrxG), which label chromatin with repressive or active histone marks.

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 ...

Treatment patterns and clinical outcomes in real‐world patients with small‐cell lung cancer in South Korea: A single‐center experience

International Journal of Cancer, EarlyView.
What's New? The emerging role of immunotherapy in small‐cell lung cancer treatment has not been fully elucidated, particularly outside of clinical trials. This single‐center retrospective cohort study examined real‐world treatment patterns and overall survival in South Korea during the 2018–2023 period.

Divalent and multivalent cations control liquid-like assembly of poly(ADP-ribosyl)ated PARP1 into multimolecular associates in vitro

Communications Biology
The formation of nuclear biomolecular condensates is often associated with local accumulation of proteins at a site of DNA damage. The key role in the formation of DNA repair foci belongs to PARP1, which is a sensor of DNA damage and catalyzes the ...

Poly (ADP-Ribose) Polymerase Mediates Diabetes-Induced Retinal Neuropathy

Mediators of Inflammation, 2013
Retinal neuropathy is an early event in the development of diabetic retinopathy. One of the potential enzymes that are activated by oxidative stress in the diabetic retina is poly (ADP-ribose) polymerase (PARP).
