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 ...
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2015-10-29)
BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ...
Oncogenic KRAS sensitizes premalignant, but not malignant cells, to Noxa-dependent apoptosis through the activation of the MEK/ERK pathway.
(IMPACT JOURNALS LLC, 2015-05-10)
KRAS is mutated in about 20-25% of all human cancers and especially in pancreatic, lung and colorectal tumors. Oncogenic KRAS stimulates several pro-survival pathways, but it also triggers the trans-activation of pro-apoptotic ...
CDK1 Is a Synthetic Lethal Target for KRAS Mutant Tumours.
(PUBLIC LIBRARY SCIENCE, 2016-02-16)
Activating KRAS mutations are found in approximately 20% of human cancers but no RAS-directed therapies are currently available. Here we describe a novel, robust, KRAS synthetic lethal interaction with the cyclin dependent ...
Targeting TRIM37-driven centrosome dysfunction in 17q23-amplified breast cancer.
(NATURE PORTFOLIO, 2020-09-17)
Genomic instability is a hallmark of cancer, and has a central role in the initiation and development of breast cancer1,2. The success of poly-ADP ribose polymerase inhibitors in the treatment of breast cancers that are ...
Cells Lacking the RB1 Tumor Suppressor Gene Are Hyperdependent on Aurora B Kinase for Survival.
(AMER ASSOC CANCER RESEARCH, 2019-02-01)
Small cell lung cancer (SCLC) accounts for 15% of lung cancers and is almost always linked to inactivating RB1 and TP53 mutations. SCLC frequently responds, albeit briefly, to chemotherapy. The canonical function of the ...
E-Cadherin/ROS1 Inhibitor Synthetic Lethality in Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2018-04-01)
The cell adhesion glycoprotein E-cadherin (CDH1) is commonly inactivated in breast tumors. Precision medicine approaches that exploit this characteristic are not available. Using perturbation screens in breast tumor cells ...
Targeting the Vulnerability of RB Tumor Suppressor Loss in Triple-Negative Breast Cancer.
(CELL PRESS, 2018-01-30)
Approximately 30% of triple-negative breast cancers (TNBCs) exhibit functional loss of the RB tumor suppressor, suggesting a target for precision intervention. Here, we use drug screens to identify agents specifically ...
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) ...
