Using an in-vivo syngeneic spontaneous metastasis model identifies ID2 as a promoter of breast cancer colonisation in the brain.
(BMC, 2019-01-14)
BACKGROUND: Dissemination of breast cancers to the brain is associated with poor patient outcome and limited therapeutic options. In this study we sought to identify novel regulators of brain metastasis by profiling mouse ...
In Vivo Modeling of Chemoresistant Neuroblastoma Provides New Insights into Chemorefractory Disease and Metastasis.
(AMER ASSOC CANCER RESEARCH, 2019-10-15)
Neuroblastoma is a pediatric cancer that is frequently metastatic and resistant to conventional treatment. In part, a lack of natively metastatic, chemoresistant in vivo models has limited our insight into the development ...
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 ...
ARID1A influences HDAC1/BRD4 activity, intrinsic proliferative capacity and breast cancer treatment response.
(NATURE PORTFOLIO, 2020-02-01)
Using genome-wide clustered regularly interspaced short palindromic repeats (CRISPR) screens to understand endocrine drug resistance, we discovered ARID1A and other SWI/SNF complex components as the factors most critically ...
The deubiquitinase USP9X regulates FBW7 stability and suppresses colorectal cancer.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-04-02)
The tumor suppressor FBW7 targets oncoproteins such as c-MYC for ubiquitylation and is mutated in several human cancers. We noted that in a substantial percentage of colon cancers, FBW7 protein is undetectable despite the ...
C/EBPα mediates the growth inhibitory effect of progestins on breast cancer cells.
(WILEY, 2019-09-16)
Steroid hormones are key gene regulators in breast cancer cells. While estrogens stimulate cell proliferation, progestins activate a single cell cycle followed by proliferation arrest. Here, we use biochemical and genome-wide ...
Transcriptomic analysis of human primary breast cancer identifies fatty acid oxidation as a target for metformin.
(NATURE PUBLISHING GROUP, 2020-01-21)
BACKGROUND: Epidemiological studies suggest that metformin may reduce the incidence of cancer in patients with diabetes and multiple late phase clinical trials assessing the potential of repurposing this drug are underway. ...
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 ...
BRD4 facilitates replication stress-induced DNA damage response.
(NATURE PUBLISHING GROUP, 2018-07-12)
Previous reports have demonstrated that select cancers depend on BRD4 to regulate oncogenic gene transcriptional programs. Here we describe a novel role for BRD4 in DNA damage response (DDR). BRD4 associates with and ...
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 ...
