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 ...
The discovery of potent ribosomal S6 kinase inhibitors by high-throughput screening and structure-guided drug design.
(IMPACT JOURNALS LLC, 2013-08-25)
The ribosomal P70 S6 kinases play a crucial role in PI3K/mTOR regulated signalling pathways and are therefore potential targets for the treatment of a variety of diseases including diabetes and cancer. In this study we ...
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. ...
Oncogenic RAC1 and NRAS drive resistance to endoplasmic reticulum stress through MEK/ERK signalling.
(ELSEVIER SCIENCE INC, 2018-04-01)
Cancer cells are able to survive under conditions that cause endoplasmic reticulum stress (ER-stress), and can adapt to this stress by upregulating cell-survival signalling pathways and down-regulating apoptotic pathways. ...
Dissecting mechanisms of resistance to targeted drug combination therapy in human colorectal cancer.
(NATURE PUBLISHING GROUP, 2019-06-20)
Genomic alterations in cancer cells result in vulnerabilities that clinicians can exploit using molecularly targeted drugs, guided by knowledge of the tumour genotype. However, the selective activity of these drugs exerts ...
Single-Cell Dynamics Determines Response to CDK4/6 Inhibition in Triple-Negative Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2017-09-15)
Purpose: Triple-negative breast cancer (TNBC) is a heterogeneous subgroup of breast cancer that is associated with a poor prognosis. We evaluated the activity of CDK4/6 inhibitors across the TNBC subtypes and investigated ...
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 ...
The receptor protein tyrosine phosphatase PTPRB negatively regulates FGF2-dependent branching morphogenesis.
(COMPANY OF BIOLOGISTS LTD, 2017-10-15)
PTPRB is a transmembrane protein tyrosine phosphatase known to regulate blood vessel remodelling and angiogenesis. Here, we demonstrate that PTPRB negatively regulates branching morphogenesis in the mouse mammary epithelium. ...
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 ...
