Glycogen synthase kinase 3 controls migration of the neural crest lineage in mouse and Xenopus.
(NATURE PUBLISHING GROUP, 2018-03-19)
Neural crest migration is critical to its physiological function. Mechanisms controlling mammalian neural crest migration are comparatively unknown, due to difficulties accessing this cell population in vivo. Here we report ...
DNA repair deficiency sensitizes lung cancer cells to NAD+ biosynthesis blockade.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-04-02)
Synthetic lethality is an efficient mechanism-based approach to selectively target DNA repair defects. Excision repair cross-complementation group 1 (ERCC1) deficiency is frequently found in non-small-cell lung cancer ...
Compartmentalized activities of the pyruvate dehydrogenase complex sustain lipogenesis in prostate cancer.
(NATURE PUBLISHING GROUP, 2018-02-01)
The mechanisms by which mitochondrial metabolism supports cancer anabolism remain unclear. Here, we found that genetic and pharmacological inactivation of pyruvate dehydrogenase A1 (PDHA1), a subunit of the pyruvate ...
HER3-Mediated Resistance to Hsp90 Inhibition Detected in Breast Cancer Xenografts by Affibody-Based PET Imaging.
(AMER ASSOC CANCER RESEARCH, 2018-04-15)
Purpose: Recent studies have highlighted a role of HER3 in HER2-driven cancers (e.g., breast cancer), implicating the upregulation of the receptor in resistance to HER-targeted therapies and Hsp90 inhibitors (e.g., AUY922). ...
Asparagine bioavailability governs metastasis in a model of breast cancer.
(NATURE PORTFOLIO, 2018-02-15)
Using a functional model of breast cancer heterogeneity, we previously showed that clonal sub-populations proficient at generating circulating tumour cells were not all equally capable of forming metastases at secondary ...
Activation of MAPK Signaling by CXCR7 Leads to Enzalutamide Resistance in Prostate Cancer.
(AMER ASSOC CANCER RESEARCH, 2019-05-15)
Castration-resistant prostate cancer (CRPC) that has developed resistance to the new-generation androgen receptor (AR) antagonist enzalutamide is a lethal disease. Transcriptome analysis of multiple prostate cancer models ...
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 ...
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 ...
