TTV Species Diversity as a Novel Biomarker of Immune Dysregulation in Aging

open access: yesJournal of Medical Virology, Volume 97, Issue 11, November 2025.
ABSTRACT Torquetenovirus (TTV) is a prevalent virus whose clinical significance remains unclear, potentially linked to immunosenescence. This study examines TTV species in relation to immune impairment, inflammation, and cellular stress response in aging.

LAP2α preserves genome integrity through assisting RPA deposition on damaged chromatin

open access: yesGenome Biology, 2022
Background Single-stranded DNA (ssDNA) coated with replication protein A (RPA) acts as a key platform for the recruitment and exchange of genome maintenance factors in DNA damage response. Yet, how the formation of the ssDNA-RPA intermediate is regulated

The Role of PARPs in Inflammation—And Metabolic—Related Diseases: Molecular Mechanisms and Beyond

open access: yesCells, 2019
Poly(ADP-ribosyl)ation (PARylation) is an essential post-translational modification catalyzed by poly(ADP-ribose) polymerase (PARP) enzymes. Poly(ADP-ribose) polymerase 1 (PARP1) is a well-characterized member of the PARP family.

Chronic Cellular NAD Depletion Activates a Viral Infection‐Like Interferon Response Through Mitochondrial DNA Leakage

open access: yesAging Cell, Volume 24, Issue 9, September 2025.
Chronic NAD depletion in fibroblasts lowers NAD levels, increases mitochondrial mass, and triggers an interferon‐dependent inflammatory response via mtDNA leakage through VDAC1, activating the cGAS‐STING pathway. This links NAD deficiency to metabolic and inflammatory processes, with implications for diseases associated with NAD decline.

Post-Transcriptional Regulation by Poly(ADP-ribosyl)ation of the RNA-Binding Proteins

open access: yes, 2013
Gene expression is intricately regulated at the post-transcriptional level by RNA-binding proteins (RBPs) via their interactions with pre-messenger RNA (pre-mRNA) and mRNA during development.

Tankyrase Regulates Neurite Outgrowth through Poly(ADP-ribosyl)ation-Dependent Activation of β-Catenin Signaling

open access: yes, 2022
Poly(ADP-ribosyl)ation is a post-translational modification of proteins by transferring poly(ADP-ribose) (PAR) to acceptor proteins by the action of poly(ADP-ribose) polymerase (PARP).

Poly (ADP‐Ribose) Glycohydrolase‐Dependent dePARylation of PCNA Is Essential for DNA Replication

open access: yesThe FASEB Journal, Volume 39, Issue 16, 31 August 2025.
The schematic illustration of PARG‐mediated dePARylation in DNA replication. In the normal physiological condition, PARG functions as an eraser to remove PAR from PCNA and promote the interaction between FEN1 and PCNA (A). Interruption of PARG results in the accumulation of PARs in DNA replication sites, represses the interaction between PCNA and FEN1,

Targeting dePARylation for cancer therapy

open access: yesCell & Bioscience, 2020
Poly(ADP-ribosyl)ation (PARylation) mediated by poly ADP-ribose polymerases (PARPs) plays a key role in DNA damage repair. Suppression of PARylation by PARP inhibitors impairs DNA damage repair and induces apoptosis of tumor cells with repair defects ...

Nicotinamide Riboside Supplementation Benefits in Patients With Werner Syndrome: A Double‐Blind Randomized Crossover Placebo‐Controlled Trial

open access: yesAging Cell, Volume 24, Issue 8, August 2025.
Nicotinamide riboside improved arterial stiffness (cardio–ankle vascular index), reduced skin ulcer area, and showed a trend toward mitigating heel pad thinning in patients with Werner syndrome, with no serious adverse events. Metabolomic analysis revealed a significant decrease in creatinine, suggesting a potential suppression of renal functional ...
