Biomarkers Associating with PARP Inhibitor Benefit in Prostate Cancer in the TOPARP-B Trial.
(AMER ASSOC CANCER RESEARCH, 2021-11-01)
PARP inhibitors are approved for treating advanced prostate cancers (APC) with various defective DNA repair genes; however, further studies to clinically qualify predictive biomarkers are warranted. Herein we analyzed ...
The Mutational Concordance of Fixed Formalin Paraffin Embedded and Fresh Frozen Gastro-Oesophageal Tumours Using Whole Exome Sequencing.
(MDPI, 2021-01-09)
UNLABELLED: 1. BACKGROUND: The application of massively parallel sequencing has led to the identification of aberrant druggable pathways and somatic mutations within therapeutically relevant genes in gastro-oesophageal ...
HNF4A and GATA6 Loss Reveals Therapeutically Actionable Subtypes in Pancreatic Cancer.
(CELL PRESS, 2020-05-12)
Pancreatic ductal adenocarcinoma (PDAC) can be divided into transcriptomic subtypes with two broad lineages referred to as classical (pancreatic) and squamous. We find that these two subtypes are driven by distinct metabolic ...
Quantitative Assessment and Prognostic Associations of the Immune Landscape in Ovarian Clear Cell Carcinoma.
(MDPI, 2021-07-30)
Ovarian clear cell carcinoma (OCCC) is a rare subtype of epithelial ovarian cancer characterised by a high frequency of loss-of-function ARID1A mutations and a poor response to chemotherapy. Despite their generally low ...
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 ...
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 ...
ATR inhibitors as a synthetic lethal therapy for tumours deficient in ARID1A.
(NATURE PUBLISHING GROUP, 2016-12-13)
Identifying genetic biomarkers of synthetic lethal drug sensitivity effects provides one approach to the development of targeted cancer therapies. Mutations in ARID1A represent one of the most common molecular alterations ...
Analysis of Circulating Cell-Free DNA Identifies Multiclonal Heterogeneity of BRCA2 Reversion Mutations Associated with Resistance to PARP Inhibitors.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Approximately 20% of metastatic prostate cancers harbor mutations in genes required for DNA repair by homologous recombination repair (HRR) such as BRCA2 HRR defects confer synthetic lethality to PARP inhibitors (PARPi) ...
PARP inhibitors: Synthetic lethality in the clinic.
(AMER ASSOC ADVANCEMENT SCIENCE, 2017-03-17)
PARP inhibitors (PARPi), a cancer therapy targeting poly(ADP-ribose) polymerase, are the first clinically approved drugs designed to exploit synthetic lethality, a genetic concept proposed nearly a century ago. Tumors ...
