Sirtuin inhibition is synthetic lethal with BRCA1 or BRCA2 deficiency.
(NATURE PORTFOLIO, 2021-11-08)
PARP enzymes utilise NAD+ as a co-substrate for their enzymatic activity. Inhibition of PARP1 is synthetic lethal with defects in either BRCA1 or BRCA2. In order to assess whether other genes implicated in NAD+ metabolism ...
European experts consensus: BRCA/homologous recombination deficiency testing in first-line ovarian cancer.
(ELSEVIER, 2022-03-01)
BACKGROUND: Homologous recombination repair (HRR) enables fault-free repair of double-stranded DNA breaks. HRR deficiency is predicted to occur in around half of high-grade serous ovarian carcinomas. Ovarian cancers ...
Resistance to DNA repair inhibitors in cancer.
(WILEY, 2022-05-14)
The DNA damage response (DDR) represents a complex network of proteins which detect and repair DNA damage, thereby maintaining the integrity of the genome and preventing the transmission of mutations and rearranged chromosomes ...
The ubiquitin-dependent ATPase p97 removes cytotoxic trapped PARP1 from chromatin.
(NATURE PORTFOLIO, 2022-01-01)
Poly (ADP-ribose) polymerase (PARP) inhibitors elicit antitumour activity in homologous recombination-defective cancers by trapping PARP1 in a chromatin-bound state. How cells process trapped PARP1 remains unclear. Using ...
A HUWE1 defect causes PARP inhibitor resistance by modulating the BRCA1-∆11q splice variant.
(SPRINGERNATURE, 2023-09-01)
Although PARP inhibitors (PARPi) now form part of the standard-of-care for the treatment of homologous recombination defective cancers, de novo and acquired resistance limits their overall effectiveness. Previously, ...
Current and future diagnostic and treatment strategies for patients with invasive lobular breast cancer.
(ELSEVIER, 2022-08-01)
BACKGROUND: Invasive lobular breast cancer (ILC) is the second most common type of breast cancer after invasive breast cancer of no special type (NST), representing up to 15% of all breast cancers. DESIGN: Latest data on ...
ATARI trial: ATR inhibitor in combination with olaparib in gynecological cancers with ARID1A loss or no loss (ENGOT/GYN1/NCRI).
(BMJ PUBLISHING GROUP, 2021-11-01)
BACKGROUND: ARID1A (AT-rich interactive domain containing protein 1A) loss-of-function mutations have been reported in gynecological cancers, including rarer subtypes such as clear cell carcinoma. Preclinical studies ...
Identification of a Molecularly-Defined Subset of Breast and Ovarian Cancer Models that Respond to WEE1 or ATR Inhibition, Overcoming PARP Inhibitor Resistance.
(AMER ASSOC CANCER RESEARCH, 2022-10-14)
PURPOSE: PARP inhibitors (PARPi) induce synthetic lethality in homologous recombination repair (HRR)-deficient tumors and are used to treat breast, ovarian, pancreatic, and prostate cancers. Multiple PARPi resistance ...
Systemic Therapy for Hereditary Breast Cancers.
(W B SAUNDERS CO-ELSEVIER INC, 2023-02-01)
Approximately 5% to 10% of all breast cancers are hereditary; many of which are caused by pathogenic variants in genes required for homologous recombination, including BRCA1 and BRCA2. Here we discuss systemic treatment ...
Functional screening reveals HORMAD1-driven gene dependencies associated with translesion synthesis and replication stress tolerance.
(SPRINGERNATURE, 2022-08-05)
HORMAD1 expression is usually restricted to germline cells, but it becomes mis-expressed in epithelial cells in ~60% of triple-negative breast cancers (TNBCs), where it is associated with elevated genomic instability (1). ...
