Glutathione Metabolism: An Achilles' Heel of ARID1A-Deficient Tumors.
(CELL PRESS, 2019-02-11)
In this issue of Cancer Cell, Ogiwara et al. describe a novel link between the epigenetic regulator ARID1A and glutathione metabolism in cancer that is mediated by regulation of the cystine/glutamate transporter XCT. This ...
Spatially constrained tumour growth affects the patterns of clonal selection and neutral drift in cancer genomic data.
(PUBLIC LIBRARY SCIENCE, 2019-07-29)
Quantification of the effect of spatial tumour sampling on the patterns of mutations detected in next-generation sequencing data is largely lacking. Here we use a spatial stochastic cellular automaton model of tumour growth ...
Differences in Signaling Patterns on PI3K Inhibition Reveal Context Specificity in KRAS-Mutant Cancers.
(AMER ASSOC CANCER RESEARCH, 2019-08-01)
It is increasingly appreciated that drug response to different cancers driven by the same oncogene is different and may relate to differences in rewiring of signal transduction. We aimed to study differences in dynamic ...
BRET-based RAS biosensors that show a novel small molecule is an inhibitor of RAS-effector protein-protein interactions.
(ELIFE SCIENCES PUBLICATIONS LTD, 2018-07-10)
The RAS family of proteins is amongst the most highly mutated in human cancers and has so far eluded drug therapy. Currently, much effort is being made to discover mutant RAS inhibitors and in vitro screening for RAS-binding ...
Small molecule inhibitors of RAS-effector protein interactions derived using an intracellular antibody fragment.
(NATURE PORTFOLIO, 2018-08-09)
Targeting specific protein-protein interactions (PPIs) is an attractive concept for drug development, but hard to implement since intracellular antibodies do not penetrate cells and most small-molecule drugs are considered ...
KRAS and BRAF mutations in circulating tumour DNA from locally advanced rectal cancer.
(NATURE PORTFOLIO, 2018-01-23)
There are limited data on circulating, cell-free, tumour (ct)DNA analysis in locally advanced rectal cancer (LARC). Digital droplet (dd)PCR was used to investigate KRAS/BRAF mutations in ctDNA from baseline blood samples ...
Diagnostic and Therapeutic Biomarkers in Glioblastoma: Current Status and Future Perspectives.
(HINDAWI LTD, 2017-01-01)
Glioblastoma (GBM) is a primary neuroepithelial tumor of the central nervous system, characterized by an extremely aggressive clinical phenotype. Patients with GBM have a poor prognosis and only 3-5% of them survive for ...
DNA replication stress mediates APOBEC3 family mutagenesis in breast cancer.
(BMC, 2016-09-15)
BACKGROUND: The APOBEC3 family of cytidine deaminases mutate the cancer genome in a range of cancer types. Although many studies have documented the downstream effects of APOBEC3 activity through next-generation sequencing, ...
Characterizing and targeting PDGFRA alterations in pediatric high-grade glioma.
(IMPACT JOURNALS LLC, 2016-10-04)
Pediatric high-grade glioma (HGG, WHO Grade III and IV) is a devastating brain tumor with a median survival of less than two years. PDGFRA is frequently mutated/ amplified in pediatric HGG, but the significance of this ...
Immunogenomic analyses associate immunological alterations with mismatch repair defects in prostate cancer.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-10-01)
BACKGROUND: Understanding the integrated immunogenomic landscape of advanced prostate cancer (APC) could impact stratified treatment selection. METHODS: Defective mismatch repair (dMMR) status was determined by either loss ...
