Poly(ADP-ribose) polymerase-1 : domain C structure, poly(ADP-ribosyl)ation sites and physiological functions

, 2008
textPoly(ADP-ribose) polymerase-1 (PARP-1) is an abundant nuclear protein that catalyzes the cleavage of NAD⁺ into nicotinamide and ADP-ribose moiety, the latter of which may be covalently attached as a branched polymer of poly(ADP-ribose) to PARP-1 ...

Ovarian Cancer: Epidemiology, Disease Mechanisms, New Diagnosis and Treatment Strategies, and Research Directions

iNew Medicine, EarlyView.
ABSTRACT Ovarian cancer (OC) continues to be the deadliest gynecological malignancy and a significant cause of cancer‐related mortality among women worldwide. Standard treatment strategies typically entail platinum‐based chemotherapy in conjunction with cytoreductive surgery.

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) glycohydrolase mediates oxidative and excitotoxic neuronal death

, 2001
Excessive activation of poly(ADP-ribose) polymerase 1 (PARP1) leads to NAD(+) depletion and cell death during ischemia and other conditions that generate extensive DNA damage.

Targeting Renal IGFBP7 With Tetrahedral Framework Nucleic Acid‐Delivered siRNA Alleviates Acute Kidney Injury

iNew Medicine, EarlyView.
A tFNA‐based siRNA delivery system targeting IGFBP7 effectively silences IGFBP7 expression and attenuates renal dysfunction, tubular injury, and cell death in both septic (CLP) and ischemic (I/R) murine models of acute kidney injury. ABSTRACT Acute kidney injury (AKI) is a common and serious clinical condition, yet effective targeted therapies remain ...

PARG Mutation Uncovers Critical Structural Determinant for Poly(ADP-Ribose) Hydrolysis and Chromatin Regulation in Embryonic Stem Cells

Cells
Poly(ADP-ribosyl)ation is a crucial posttranslational modification that governs gene expression, chromatin remodeling, and cellular homeostasis. This dynamic process is mediated by the opposing activities of poly(ADP-ribose) polymerases (PARPs), which ...

The TRPM2–PARP‐1 Axis Involvement in Bisphenol A and Nonylphenol‐Induced Ferroptosis in Trigeminal Ganglion Cells

Journal of Applied Toxicology, EarlyView.
ABSTRACT Environmental contaminants like bisphenol A (BPA) and nonylphenol (NP) are recognized neurotoxicants; however, the molecular mechanisms underlying their impact on sensory ganglia, specifically the trigeminal ganglion (TG), remain critically underexplored.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Studies on Poly(ADP-ribose) Metabolism and Chromatin Structure [PDF]

, 1988
In these studies, a procedure which allowed the in vivo labeling and detection of poly(ADP-ribose) was combined with nuclear fractionation techniques to analyze the nuclear distribution of ADP-ribose polymers.
