NAD+ analog reveals PARP-1 substrate-blocking mechanism and allosteric communication from catalytic center to DNA-binding domains

Nature Communications, 2018
Poly(ADP-ribose) polymerases (PARPs) catalyse ADP-ribose posttranslational modifications using NAD+ as a substrate. Here, the authors present the crystal structure of PARP-1 bound to the non-hydrolyzable NAD+ analog BAD and provide insights into the ...

Inhibition of poly(ADP-ribose) polymerase interferes with Trypanosoma cruzi infection and proliferation of the parasite.

PLoS ONE, 2012
Poly(ADP-ribosylation) is a post-translational covalent modification of proteins catalyzed by a family of enzymes termed poly(ADP-ribose) polymerases (PARPs).

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 Objective Acute kidney injury (AKI) is a common and serious clinical condition, yet effective targeted ...

Reversing brain aging: Targeting energy metabolism in endogenous neural stem cells

Interdisciplinary Medicine, EarlyView.
Mechanism of endogenous neural stem cells (eNSCs) energy metabolism disorder leading to brain aging and targeted eNSCs intervention strategies (By biorender). The disorder of energy metabolism of eNSCs can lead to their resting and aging, and eventually lead to brain aging.

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.

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.

Bisphenol A and Its Analogs: Toxicity Analysis in Mouse and Rat Liver—A Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA) and its analogs are widely recognized for their use in industry and plastic manufacturing. Consequently, humans and animals are continually exposed to various substances in their daily lives. This review evaluates the hepatic toxicity of BPA and its analogs in mice and rats, with particular emphasis on molecular mechanisms ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and
