Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

The Dichotomy of the Poly(ADP-Ribose) Polymerase-Like Thermozyme from Sulfolobus solfataricus
The first evidence of an ADP-ribosylating activity in Archaea was obtained in Sulfolobus solfataricus(strain MT-4) where a poly(ADP-ribose) polymerase (PARP)-like thermoprotein, defined with the acronymous PARPSso, was found.

Evaluation of melanin-targeted radiotherapy in combination with radiosensitizing drugs for the treatment of melanoma [PDF]
The incidence of malignant melanoma is rising faster than that of any other cancer in the United States. An [131I]-labeled benzamide - [131I]MIP-1145 - selectively targets melanin, reduces melanoma tumor burden and increases survival in preclinical ...

Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

Poly(ADP-Ribosyl)ation affects stabilization of CHE-1 protein in response to DNA damage [PDF]
Post-translation modifications play a crucial role in coordinating the cellular response to DNA damage. Double strand DNA breaks (DSBs) trigger the activation of ATM and Chk2 kinases, which represent the primary transducers in the signalling cascade ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

TIPARP is involved in the regulation of intraocular pressure
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.

Autophagy in DNA Damage Response [PDF]
DNA damage response (DDR) involves DNA repair, cell cycle regulation and apoptosis, but autophagy is also suggested to play a role in DDR. Autophagy can be activated in response to DNA-damaging agents, but the exact mechanism underlying this activation ...

Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Poly (ADP-ribose) polymerase inhibitors in the management of ovarian cancer
There is considerable interest and enthusiasm within the clinical gynecologic oncology community regarding the potential for poly (ADP-ribose) polymerase inhibitors to play a critically relevant role in the management of epithelial ovarian cancer and ...
