Increased PARylation impacts the DNA methylation process in type 2 diabetes mellitus [PDF]

open access: yes, 2021
Epigenetic modifications, such as DNA methylation, can influence the genetic susceptibility to type 2 diabetes mellitus (T2DM) and the progression of the disease.

The Oxidative Damage and Inflammation Mechanisms in GERD-Induced Barrett’s Esophagus

open access: yesFrontiers in Cell and Developmental Biology, 2022
Barrett’s esophagus is a major complication of gastro-esophageal reflux disease and an important precursor lesion for the development of Barrett’s metaplasia and esophageal adenocarcinoma.

Proteomic Investigation of Phosphorylation Sites in Poly(ADP-ribose) Polymerase-1 and Poly(ADP-ribose) Glycohydrolase [PDF]

open access: yesJournal of Proteome Research, 2008
Phosphorylation is a very common post-translational modification event known to modulate a wide range of biological responses. Beyond the regulation of protein activity, the interrelation of phosphorylation with other post-translational mechanisms is responsible for the control of diverse signaling pathways.

Chromosomal Instability Drives Glioblastoma Heterogeneity and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
ABSTRACT Glioblastoma, the most aggressive and lethal form of brain cancer, is defined by profound genomic instability, with Chromosomal Instability (CIN) playing a central role in driving tumor progression, therapy resistance, and poor prognosis. CIN is characterized by numerical and structural alterations, is driven by mechanisms such as mitotic ...

Higher plants possess two structurally different poly(ADP-ribose) polymerases

open access: yes, 1998
One of the immediate reactions of the mammalian cell to many environmental stresses is a massive synthesis of poly(ADP-ribose), catalyzed by poly(ADP-ribose) polymerase (PARP).

Pemt Inhibition‐Mediated Vdac1 Oligomerization Regulates Mitochondrial Dysfunction, Apoptosis, and Inflammation in High‐Fat Diet‐Derived Liver Injury

open access: yesAdvanced Science, EarlyView.
ABSTRACT High‐fat diet (HFD)‐induced hepatic injury represents a pathology observed across vertebrates, yet the underlying mechanisms remain incompletely understood. Herein, the present study identifies phosphatidylethanolamine methyltransferase (Pemt), a key enzyme in phosphatidylcholine synthesis, as a critical regulator of mitochondrial homeostasis ...

Synthesis of Bispecific Antibody Conjugates Using Functionalized Poly-ADP-ribose Polymers

open access: yes, 2023
Poly-ADP-ribose (PAR) is a natural type of polymer derived from enzymatic reactions catalyzed by cellular poly(ADP-ribose) polymerases (PARPs). Given its notable solubility and biocompatibility, the PAR polymer may function as effective carriers for ...

Regulation of Rad52-dependent replication fork recovery through serine ADP-ribosylation of PolD3

open access: yesNature Communications, 2023
Although Poly(ADP-ribose)-polymerases (PARPs) are key regulators of genome stability, how site-specific ADP-ribosylation regulates DNA repair is unclear.

TDP‐43 Aggregation: The Healthy‐Toxic Balance of the Prion‐Like Domain

open access: yesAdvanced Science, EarlyView.
TDP‐43 function relies on a delicate balance between reversible phase‐separated states and irreversible aggregation. Under physiological conditions, TDP‐43 forms dynamic droplets and oligomers that support normal cellular functions. In pathological contexts, this balance shifts toward aberrant aggregation, leading to toxic species.

NAD+ Metabolism Licenses Zygotic Genome Activation via PARP7‐Mediated ADP‐Ribosylation of UHRF1 in Mouse Early Embryos

open access: yesAdvanced Science, EarlyView.
This study uncovers a metabolic‐epigenetic axis licensing zygotic genome activation (ZGA) in mouse embryos. A developmental decline in NAD+ levels activates PARP7, which mono‐ADP‐ribosylates and stabilizes UHRF1. This modification promotes the establishment of permissive histone acetylation marks, thereby facilitating timely ZGA.
