Mechanisms of poly(ADP‐ribose) polymerase catalysis; mono‐ADP‐ribosylation of poly(ADP‐ribose) polymerase at nanomolar concentrations of NAD [PDF]
FEBS Letters, 1986 Calf thymus and rat liver poly(ADP‐ribose) polymerase enzymes, and the polymerase present in extracts of rat liver nuclei synthesize unstable mono‐ADP‐ribose protein adducts at 100 nM or lower NAD concentrations. The isolated enzyme‐mono‐ADP‐ribose adduct hydrolyses to ADP‐ribose and enzyme protein at pH values slightly above 7.0 indicating a ...

Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Biosensors, 2023 This work reports the development of a fluorescence method for the detection of poly(ADP-ribose) polymerase-1 (PARP1), in which a phenylboronic acid-modified fluorescein isothiocyanate dye (FITC-PBA) was used to recognize the formed poly(ADP-ribose) (PAR)

Molecular Oncology, EarlyView.We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Neoplasia: An International Journal for Oncology Research, 2014 Poly(ADP-ribose) polymerase-1 (PARP1) catalyzes the poly(ADP-ribosyl)ation of protein acceptors using NAD+ as the substrate is now considered as an important target for development of anticancer therapy. PARP1 is known to be post-translationally modified

DNA damage in Nijmegen Breakage Syndrome cells leads to PARP hyperactivation and increased oxidative stress. [PDF]
PLoS Genetics, 2012 Nijmegen Breakage Syndrome (NBS), an autosomal recessive genetic instability syndrome, is caused by hypomorphic mutation of the NBN gene, which codes for the protein nibrin.

PARPs and ADP-Ribosylation in Chronic Inflammation: A Focus on Macrophages
Pathogens, 2023 Aberrant adenosine diphosphate-ribose (ADP)-ribosylation of proteins and nucleic acids is associated with multiple disease processes such as infections and chronic inflammatory diseases. The poly(ADP-ribose) polymerase (PARP)/ADP-ribosyltransferase (ART)

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3
Molecular Oncology, EarlyView.PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

TIPARP is involved in the regulation of intraocular pressure
Communications Biology, 2022 TIPARP, an inducible poly-ADP-ribose polymerase, is identified as a novel regulator of intraocular pressure through modulation of extracellular matrix and cell cytoskeleton proteins in trabecular meshwork cells.
