Coupling bimolecular PARylation biosensors with genetic screens to identify PARylation targets.
(NATURE PUBLISHING GROUP, 2018-05-22)
Poly (ADP-ribose)ylation is a dynamic protein modification that regulates multiple cellular processes. Here, we describe a system for identifying and characterizing PARylation events that exploits the ability of a PBZ ...
MIR21 Drives Resistance to Heat Shock Protein 90 Inhibition in Cholangiocarcinoma.
(W B SAUNDERS CO-ELSEVIER INC, 2018-03-01)
BACKGROUND & AIMS: Cholangiocarcinomas (CCA) are resistant to chemotherapy, so new therapeutic agents are needed. We performed a screen to identify small-molecule compounds that are active against CCAs. Levels of microRNA ...
Pediatric and adult glioblastoma radiosensitization induced by PI3K/mTOR inhibition causes early metabolic alterations detected by nuclear magnetic resonance spectroscopy.
(IMPACT JOURNALS LLC, 2017-07-18)
Poor outcome for patients with glioblastomas is often associated with radioresistance. PI3K/mTOR pathway deregulation has been correlated with radioresistance; therefore, PI3K/mTOR inhibition could render tumors radiosensitive. ...
Neural Precursor-Derived Pleiotrophin Mediates Subventricular Zone Invasion by Glioma.
(CELL PRESS, 2017-08-24)
The lateral ventricle subventricular zone (SVZ) is a frequent and consequential site of pediatric and adult glioma spread, but the cellular and molecular mechanisms mediating this are poorly understood. We demonstrate that ...
Combined MYC and P53 defects emerge at medulloblastoma relapse and define rapidly progressive, therapeutically targetable disease.
(CELL PRESS, 2015-01-12)
We undertook a comprehensive clinical and biological investigation of serial medulloblastoma biopsies obtained at diagnosis and relapse. Combined MYC family amplifications and P53 pathway defects commonly emerged at relapse, ...
Complementary genetic screens identify the E3 ubiquitin ligase CBLC, as a modifier of PARP inhibitor sensitivity.
(IMPACT JOURNALS LLC, 2015-05-10)
Based on a series of basic, preclinical and clinical studies, the Poly (ADP-ribose) Polymerase 1 (PARP1) inhibitor, olaparib, has recently been approved for use in ovarian cancer patients with BRCA1 or BRCA2 mutations. By ...
Intra-tumor genetic heterogeneity and alternative driver genetic alterations in breast cancers with heterogeneous HER2 gene amplification.
(BMC, 2015-05-22)
BACKGROUND: HER2 is overexpressed and amplified in approximately 15% of invasive breast cancers, and is the molecular target and predictive marker of response to anti-HER2 agents. In a subset of these cases, heterogeneous ...
Pten Regulates Epithelial Cytodifferentiation during Prostate Development.
(PUBLIC LIBRARY SCIENCE, 2015-06-15)
Gene expression and functional studies have indicated that the molecular programmes involved in prostate development are also active in prostate cancer. PTEN has been implicated in human prostate cancer and is frequently ...
Phosphoproteomic Profiling Reveals ALK and MET as Novel Actionable Targets across Synovial Sarcoma Subtypes.
(AMER ASSOC CANCER RESEARCH, 2017-08-15)
Despite intensive multimodal treatment of sarcomas, a heterogeneous group of malignant tumors arising from connective tissue, survival remains poor. Candidate-based targeted treatments have demonstrated limited clinical ...
Quantitative phosphoproteomic analysis of acquired cancer drug resistance to pazopanib and dasatinib.
(ELSEVIER SCIENCE BV, 2018-01-06)
UNLABELLED: Acquired drug resistance impacts the majority of patients being treated with tyrosine kinase inhibitors (TKIs) and remains a key challenge in modern anti-cancer therapy. The lack of clinically effective therapies ...
