Second-Generation HSP90 Inhibitor Onalespib Blocks mRNA Splicing of Androgen Receptor Variant 7 in Prostate Cancer Cells.
(AMER ASSOC CANCER RESEARCH, 2016-05-01)
Resistance to available hormone therapies in prostate cancer has been associated with alternative splicing of androgen receptor (AR) and specifically, the expression of truncated and constitutively active AR variant 7 ...
Androgen receptor splice variant-7 expression emerges with castration resistance in prostate cancer.
(AMER SOC CLINICAL INVESTIGATION INC, 2019-01-02)
BACKGROUND: Liquid biopsies have demonstrated that the constitutively active androgen receptor splice variant-7 (AR-V7) associates with reduced response and overall survival from endocrine therapies in castration-resistant ...
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 ...
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 ...
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 ...
Drug discovery in advanced prostate cancer: translating biology into therapy.
(NATURE PUBLISHING GROUP, 2016-10-01)
Castration-resistant prostate cancer (CRPC) is associated with a poor prognosis and poses considerable therapeutic challenges. Recent genetic and technological advances have provided insights into prostate cancer biology ...
CRISPR screens identify genomic ribonucleotides as a source of PARP-trapping lesions.
(NATURE PUBLISHING GROUP, 2018-07-12)
The observation that BRCA1- and BRCA2-deficient cells are sensitive to inhibitors of poly(ADP-ribose) polymerase (PARP) has spurred the development of cancer therapies that use these inhibitors to target deficiencies in ...
IL-23 secreted by myeloid cells drives castration-resistant prostate cancer.
(NATURE PORTFOLIO, 2018-07-19)
Patients with prostate cancer frequently show resistance to androgen-deprivation therapy, a condition known as castration-resistant prostate cancer (CRPC). Acquiring a better understanding of the mechanisms that control ...
Patient-derived organoids model treatment response of metastatic gastrointestinal cancers.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-02-23)
Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from ...
Modulation of Plasma Metabolite Biomarkers of the MAPK Pathway with MEK Inhibitor RO4987655: Pharmacodynamic and Predictive Potential in Metastatic Melanoma.
(AMER ASSOC CANCER RESEARCH, 2017-10-01)
MAPK pathway activation is frequently observed in human malignancies, including melanoma, and is associated with sensitivity to MEK inhibition and changes in cellular metabolism. Using quantitative mass spectrometry-based ...
