NADP+ is an endogenous PARP inhibitor in DNA damage response and tumor suppression
Cancer cells respond differently to inhibitors of Poly (ADP-ribose) polymerase. Here the authors reveal that ovarian cancer cells with higher cellular NADP+ levels are more sensitive to clinically relevant PARP1 inhibitors and show that NADP+ act as an ...

Targeted Therapy in Ovarian Cancer
Ovarian cancer (OC) is associated with a dismal prognosis and lack of curative treatment. Increased understanding of OC biology has led to the development of several targeted therapies, including antiangiogenic agents and poly(ADP-ribose) polymerase ...

Radiosensitization with an inhibitor of poly(ADP-ribose) glycohydrolase: A comparison with the PARP1/2/3 inhibitor olaparib [PDF]
Upon DNA binding the poly(ADP-ribose) polymerase family of enzymes (PARPs) add multiple ADP-ribose subunits to themselves and other acceptor proteins.

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.

Mutations in the homologous recombination proteins BRCA1 and BRCA2 can sensitize cells to treatment with inhibitors of poly-ADP-ribose polymerase 1 (PARPi), but resistance to the treatment can occur.

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.

A guide to poly ADP-ribose polymerase inhibitor (PARPi) toxicity management [PDF]
Ovarian cancer is the fifth most common cause of cancer-related death in women and is the leading cause of gynecologic-related deaths in the United States.[1 2][1] Only ~40% of patients with ovarian cancer achieve a cure and the 5-year overall survival is ~47%.[1][1] The majority of ...

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.

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...

Targeting CARM1 in ovarian cancer with EZH2 and PARP inhibitors
Coactivator-associated arginine methyltransferase 1 (CARM1)-expressing high-grade serous ovarian cancers are characterized by poor prognosis and limited therapeutic options.
