Targeted Therapy in Ovarian Cancer

healthbook TIMES. Oncology Hematology, 2021
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 ...

Defective DNA repair mechanisms in prostate cancer: impact of olaparib [PDF]

, 2017
The field of prostate oncology has continued to change dramatically. It has truly become a field that is intensely linked to molecular genetic alterations, especially DNA-repair defects.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Identification of regulators of poly-ADP-ribose polymerase inhibitor response through complementary CRISPR knockout and activation screens

Nature Communications, 2020
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.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
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.

Nutrition-Based Modulation of Poly-ADP-Ribosylation and its possible role in Alzheimer’s disease [PDF]

, 2015
Alzheimer’s Disease (AD) is the most common neurodegenerative disease and the main reason of dementia in the elderly. On the pathological point of view, it is characterized by extracellular aggregates of amyloid peptides and intracellular deposits of tau

Autophagy in DNA Damage Response [PDF]

, 2015
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 ...

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

Molecular Oncology, EarlyView.
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.

Targeting CARM1 in ovarian cancer with EZH2 and PARP inhibitors

Molecular & Cellular Oncology, 2020
Coactivator-associated arginine methyltransferase 1 (CARM1)-expressing high-grade serous ovarian cancers are characterized by poor prognosis and limited therapeutic options.

Poly(ADP-Ribosyl)ation affects stabilization of CHE-1 protein in response to DNA damage [PDF]

, 2011
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 ...
