ARH Family of ADP-Ribose-Acceptor Hydrolases

Cells, 2022
The ARH family of ADP-ribose-acceptor hydrolases consists of three 39-kDa members (ARH1-3), with similarities in amino acid sequence. ARH1 was identified based on its ability to cleave ADP-ribosyl-arginine synthesized by cholera toxin.

Exploration and verification of the mechanism of PARP1/SIRT6/poly(ADP-ribosyl)ation in regulating zearalenone-induced injury in bovine sertoli cells

Ecotoxicology and Environmental Safety
Zearalenone (ZEA) is a prevalent mycotoxin in feed, known for its potent reproductive toxicity that poses a significant threat to male reproductive function. Sertoli cells (SCs) are essential for spermatogenesis.

ADP‐ribosylation: An emerging regulator of the epigenome

Molecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

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

Hsp90 Inhibition on the Western Blot: N‐Terminal Versus C‐Terminal Inhibitors in Breast Cancer

Medicinal Research Reviews, EarlyView.
ABSTRACT Heat shock protein 90 (Hsp90) is an established and clinically validated anticancer target. By regulating the folding and maturation of diverse client proteins, it is indirectly involved in carcinogenesis. Key breast cancer oncogenic drivers, including estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, are ...

Parp3 assists muscle function and skeletal muscle differentiation by selectively adjusting H3K27me3 enrichment

iScience
Summary: Poly(ADP-ribose) polymerase 3 (Parp3) is known for its role in DNA repair, mitotic division, and cancer aggressiveness. Still, its physiological roles have yet to be defined.

Harnessing benzamides as plant stress inhibitors, growth promoters and in management of crop resilience—A review

Plant Biology, EarlyView.
Benzamides boost crop resilience by inhibiting poly(ADP‐ribose) polymerase (PARP) to enhance stress tolerance and, through their antimicrobial, herbicidal, and insecticidal derivatives, they offer broad protection for sustainable crop improvement. Abstract Benzamides have emerged as potent stress inhibitors and growth promoters in plant biotechnology ...

Regulation of E2F1-induced apoptosis by poly(ADP-ribosyl)ation. [PDF]

Cell Death Differ, 2015
The transcription factor adenovirus E2 promoter-binding factor (E2F)-1 normally enhances cell-cycle progression, but it also induces apoptosis under certain conditions, including DNA damage and serum deprivation. Although DNA damage facilitates the phosphorylation and stabilization of E2F1 to trigger apoptosis, how serum starvation renders cells ...

ROS‐ATM‐CBP axis‐mediated PARP1 lactylation aggravates doxorubicin‐induced cardiotoxicity

Clinical and Translational Medicine, Volume 16, Issue 8, August 2026.
ROS function as signalling molecules to promote CBP‐mediated PARP1 lactylation in an ATM dependent manner, which induces PARP1 PARylation and ultimate cell apoptosis. CBP and SIRT1 as specific lactyltransferase and delactylase of PARP1. Lactylation of PARP1 depends on the LDHA activity and lactate production.

Rapamycin inhibits poly(ADP-ribosyl)ation in intact cells [PDF]

Biochemical and Biophysical Research Communications, 2009
Rapamycin is an immunosuppressive drug, which inhibits the mammalian target of rapamycin (mTOR) kinase activity inducing changes in cell proliferation. Synthesis of poly(ADP-ribose) (PAR) is an immediate cellular response to genotoxic stress catalyzed mostly by poly(ADP-ribose) polymerase 1 (PARP-1), which is also controlled by signaling pathways ...
