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 ...
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 ...
SF3B1 hotspot mutations confer sensitivity to PARP inhibition by eliciting a defective replication stress response.
(NATURE PORTFOLIO, 2023-08-01)
SF3B1 hotspot mutations are associated with a poor prognosis in several tumor types and lead to global disruption of canonical splicing. Through synthetic lethal drug screens, we identify that SF3B1 mutant (SF3B1MUT) cells ...
Longitudinal profiling identifies co-occurring BRCA1/2 reversions, TP53BP1, RIF1 and PAXIP1 mutations in PARP inhibitor-resistant advanced breast cancer.
(Elsevier BV, 2024-01-19)
BACKGROUND: Resistance to therapies that target homologous recombination deficiency (HRD) in breast cancer limits their overall effectiveness. Multiple, preclinically validated, mechanisms of resistance have been proposed, ...
MND1 and PSMC3IP control PARP inhibitor sensitivity in mitotic cells.
(CELL PRESS, 2023-05-30)
The PSMC3IP-MND1 heterodimer promotes meiotic D loop formation before DNA strand exchange. In genome-scale CRISPR-Cas9 mutagenesis and interference screens in mitotic cells, depletion of PSMC3IP or MND1 causes sensitivity ...
SMG8/SMG9 Heterodimer Loss Modulates SMG1 Kinase to Drive ATR Inhibitor Resistance.
(AMER ASSOC CANCER RESEARCH, 2022-11-02)
UNLABELLED: Gastric cancer represents the third leading cause of global cancer mortality and an area of unmet clinical need. Drugs that target the DNA damage response, including ATR inhibitors (ATRi), have been proposed ...
Cancer-associated FBXW7 loss is synthetic lethal with pharmacological targeting of CDC7.
(WILEY, 2023-10-22)
The F-box and WD repeat domain containing 7 (FBXW7) tumour suppressor gene encodes a substrate-recognition subunit of Skp, cullin, F-box (SCF)-containing complexes. The tumour-suppressive role of FBXW7 is ascribed to its ...
Functional annotation of the 2q35 breast cancer risk locus implicates a structural variant in influencing activity of a long-range enhancer element.
(CELL PRESS, 2021-07-01)
A combination of genetic and functional approaches has identified three independent breast cancer risk loci at 2q35. A recent fine-scale mapping analysis to refine these associations resulted in 1 (signal 1), 5 (signal 2), ...
