AhR controls redox homeostasis and shapes the tumor microenvironment in BRCA1-associated breast cancer.
(NATL ACAD SCIENCES, 2019-02-26)
Cancer cells have higher reactive oxygen species (ROS) than normal cells, due to genetic and metabolic alterations. An emerging scenario is that cancer cells increase ROS to activate protumorigenic signaling while activating ...
Reactive oxygen species modulate macrophage immunosuppressive phenotype through the up-regulation of PD-L1.
(NATL ACAD SCIENCES, 2019-03-05)
The combination of immune checkpoint blockade with chemotherapy is currently under investigation as a promising strategy for the treatment of triple negative breast cancer (TNBC). Tumor-associated macrophages (TAMs) are ...
Mutant IDH1 Downregulates ATM and Alters DNA Repair and Sensitivity to DNA Damage Independent of TET2.
(CELL PRESS, 2016-08-08)
Mutations in the isocitrate dehydrogenase-1 gene (IDH1) are common drivers of acute myeloid leukemia (AML) but their mechanism is not fully understood. It is thought that IDH1 mutants act by inhibiting TET2 to alter DNA ...
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 ...
PLK1 Activation in Late G2 Sets Up Commitment to Mitosis.
(CELL PRESS, 2017-06-06)
Commitment to mitosis must be tightly coordinated with DNA replication to preserve genome integrity. While we have previously established that the timely activation of CyclinB1-Cdk1 in late G2 triggers mitotic entry, the ...
The cryoelectron microscopy structure of the human CDK-activating kinase.
(NATL ACAD SCIENCES, 2020-09-15)
The human CDK-activating kinase (CAK), a complex composed of cyclin-dependent kinase (CDK) 7, cyclin H, and MAT1, is a critical regulator of transcription initiation and the cell cycle. It acts by phosphorylating the ...
Circulating tumour DNA analysis to direct therapy in advanced breast cancer (plasmaMATCH): a multicentre, multicohort, phase 2a, platform trial.
(ELSEVIER SCIENCE INC, 2020-10-01)
BACKGROUND: Circulating tumour DNA (ctDNA) testing might provide a current assessment of the genomic profile of advanced cancer, without the need to repeat tumour biopsy. We aimed to assess the accuracy of ctDNA testing ...
Inhibition of GPR158 by microRNA-449a suppresses neural lineage of glioma stem/progenitor cells and correlates with higher glioma grades.
(NATURE PUBLISHING GROUP, 2018-08-02)
To identify biomarkers for glioma growth, invasion and progression, we used a candidate gene approach in mouse models with two complementary brain tumour phenotypes, developing either slow-growing, diffusely infiltrating ...
Vascular Endothelial Growth Factor (VEGF) Promotes Assembly of the p130Cas Interactome to Drive Endothelial Chemotactic Signaling and Angiogenesis.
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2017-02-01)
p130Cas is a polyvalent adapter protein essential for cardiovascular development, and with a key role in cell movement. In order to identify the pathways by which p130Cas exerts its biological functions in endothelial cells ...
The MOBSTER R package for tumour subclonal deconvolution from bulk DNA whole-genome sequencing data.
(BMC, 2020-11-17)
BACKGROUND: The large-scale availability of whole-genome sequencing profiles from bulk DNA sequencing of cancer tissues is fueling the application of evolutionary theory to cancer. From a bulk biopsy, subclonal deconvolution ...
