De Novo Truncating Mutations in the Last and Penultimate Exons of PPM1D Cause an Intellectual Disability Syndrome.
(CELL PRESS, 2017-04-06)
Intellectual disability (ID) is a highly heterogeneous disorder involving at least 600 genes, yet a genetic diagnosis remains elusive in ∼35%-40% of individuals with moderate to severe ID. Recent meta-analyses statistically ...
Synthetic Lethal Targeting of ARID1A-Mutant Ovarian Clear Cell Tumors with Dasatinib.
(AMER ASSOC CANCER RESEARCH, 2016-07-01)
New targeted approaches to ovarian clear cell carcinomas (OCCC) are needed, given the limited treatment options in this disease and the poor response to standard chemotherapy. Using a series of high-throughput cell-based ...
Elevated APOBEC3B expression drives a kataegic-like mutation signature and replication stress-related therapeutic vulnerabilities in p53-defective cells.
(NATURE PUBLISHING GROUP, 2017-06-27)
BACKGROUND: Elevated APOBEC3B expression in tumours correlates with a kataegic pattern of localised hypermutation. We assessed the cellular phenotypes associated with high-level APOBEC3B expression and the influence of p53 ...
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 ...
The shieldin complex mediates 53BP1-dependent DNA repair.
(NATURE PUBLISHING GROUP, 2018-08-02)
53BP1 is a chromatin-binding protein that regulates the repair of DNA double-strand breaks by suppressing the nucleolytic resection of DNA termini1,2. This function of 53BP1 requires interactions with PTIP3 and RIF14-9, ...
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 ...
Chemosensitivity profiling of osteosarcoma tumour cell lines identifies a model of BRCAness.
(NATURE PORTFOLIO, 2018-07-13)
Osteosarcoma (OS) is an aggressive sarcoma, where novel treatment approaches are required. Genomic studies suggest that a subset of OS, including OS tumour cell lines (TCLs), exhibit genomic loss of heterozygosity (LOH) ...
A novel tankyrase inhibitor, MSC2504877, enhances the effects of clinical CDK4/6 inhibitors.
(NATURE PORTFOLIO, 2019-01-17)
Inhibition of the PARP superfamily tankyrase enzymes suppresses Wnt/β-catenin signalling in tumour cells. Here, we describe here a novel, drug-like small molecule inhibitor of tankyrase MSC2504877 that inhibits the growth ...
Circulating Cell-Free DNA to Guide Prostate Cancer Treatment with PARP Inhibition.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Biomarkers for more precise patient care are needed in metastatic prostate cancer. We have reported a phase II trial (TOPARP-A) of the PARP inhibitor olaparib in metastatic prostate cancer, demonstrating antitumor activity ...
PARP Inhibitors - Trapped in a Toxic Love Affair.
It is often the case that when an investigational cancer drug first enters clinical development, its precise mechanism of action is unclear. This was the case for PARP inhibitors (PARPi) used to treat homologous ...
