Basal Activity of a PARP1-NuA4 Complex Varies Dramatically across Cancer Cell Lines

Cell Reports, 2014
Poly(ADP-ribose) polymerases (PARPs) catalyze poly(ADP-ribose) addition onto proteins, an important posttranslational modification involved in transcription, DNA damage repair, and stem cell identity.

Rational Design of Organic Chromophores for Simultaneously Trig‐gering Redox Imbalance and Tracking Organelles in Biological Sys‐tems Under Near‐Infrared Light Irradiation

Advanced Healthcare Materials, EarlyView.
TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

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

Advanced 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 ...

New perspectives on the plant PARP family: Arabidopsis PARP3 is inactive, and PARP1 exhibits predominant poly (ADP-ribose) polymerase activity in response to DNA damage

BMC Plant Biology, 2019
Background Poly (ADP-ribosyl) ation (PARylation) is an important posttranslational modification that regulates DNA repair, gene transcription, stress responses and developmental processes in multicellular organisms.

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

Advanced 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.

Functions of PARylation in DNA Damage Repair Pathways

Genomics, Proteomics & Bioinformatics, 2016
Protein poly ADP-ribosylation (PARylation) is a widespread post-translational modification at DNA lesions, which is catalyzed by poly(ADP-ribose) polymerases (PARPs).

EDNRA Forms a Positive Feedback Loop with the Hippo/YAP Axis to Drive Triple‐Negative Breast Cancer Progression

Advanced Science, EarlyView.
Endothelin receptor type A (EDNRA) and the Hippo/YAP pathway form a self‐reinforcing loop that sustains triple‐negative breast cancer. EDNRA activates YAP through Gαq/11–Rho/ROCK–LATS signaling, while YAP/TEAD4 reciprocally drives EDNRA transcription.

The Ser/Thr protein kinase FonKin4-poly(ADP-ribose) polymerase FonPARP1 phosphorylation cascade is required for the pathogenicity of watermelon fusarium wilt fungus Fusarium oxysporum f. sp. niveum

Frontiers in Microbiology
Poly(ADP-ribosyl)ation (PARylation), catalyzed by poly(ADP-ribose) polymerases (PARPs) and hydrolyzed by poly(ADP-ribose) glycohydrolase (PARG), is a kind of post-translational protein modification that is involved in various cellular processes in fungi,

PARP Inhibitors plus Anlotinib as Bridging Therapy for Armored CAR‐T Cells in Ovarian Cancer Enhances Infiltration and Antitumor Efficacy

Advanced Science, EarlyView.
This study shows that a PARP inhibitor combined with anlotinib, administered as bridging therapy, preconditions the tumor microenvironment to enhance the infiltration and antitumor activity of subsequently infused CAR‐T cells across preclinical ovarian cancer models, supporting bridging therapy as a promising strategy to address limited CAR‐T cell ...

Targeting dePARylation for cancer therapy

Cell & 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 ...
