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 ...
Targeting cyclooxygenase by indomethacin decelerates progression of acute lymphoblastic leukemia in a xenograft model.
(AMER SOC HEMATOLOGY, 2019-11-12)
Acute lymphoblastic leukemia (ALL) develops in the bone marrow in the vicinity of stromal cells known to promote tumor development and treatment resistance. We previously showed that the cyclooxygenase (COX) inhibitor ...
Near-infrared photoimmunotherapy targeting EGFR-Shedding new light on glioblastoma treatment.
(WILEY, 2018-06-01)
Glioblastomas (GBMs) are high-grade brain tumors, differentially driven by alterations (amplification, deletion or missense mutations) in the epidermal growth factor receptor (EGFR), that carry a poor prognosis of just ...
Identifying Genetic Dependencies in Cancer by Analyzing siRNA Screens in Tumor Cell Line Panels.
(HUMANA PRESS INC, 2018-01-01)
Loss-of-function screening using RNA interference or CRISPR approaches can be used to identify genes that specific tumor cell lines depend upon for survival. By integrating the results from screens in multiple cell lines ...
The effect of FASN inhibition on the growth and metabolism of a cisplatin-resistant ovarian carcinoma model.
(WILEY, 2018-08-15)
Overexpression of fatty acid synthase (FASN), a key regulator of the de novo synthesis of fatty acids, has been demonstrated in a variety of cancers and is associated with poor prognosis and increased multidrug resistance. ...
E-Cadherin/ROS1 Inhibitor Synthetic Lethality in Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2018-04-01)
The cell adhesion glycoprotein E-cadherin (CDH1) is commonly inactivated in breast tumors. Precision medicine approaches that exploit this characteristic are not available. Using perturbation screens in breast tumor cells ...
BRD4 Promotes DNA Repair and Mediates the Formation of TMPRSS2-ERG Gene Rearrangements in Prostate Cancer.
(CELL PRESS, 2018-01-16)
BRD4 belongs to the bromodomain and extraterminal (BET) family of chromatin reader proteins that bind acetylated histones and regulate gene expression. Pharmacological inhibition of BRD4 by BET inhibitors (BETi) has indicated ...
Mind Bomb Regulates Cell Death during TNF Signaling by Suppressing RIPK1's Cytotoxic Potential.
(CELL PRESS, 2018-04-10)
Tumor necrosis factor (TNF) is an inflammatory cytokine that can signal cell survival or cell death. The mechanisms that switch between these distinct outcomes remain poorly defined. Here, we show that the E3 ubiquitin ...
A study of PD-L1 expression in KRAS mutant non-small cell lung cancer cell lines exposed to relevant targeted treatments.
(PUBLIC LIBRARY SCIENCE, 2017-10-05)
We investigated PD-L1 changes in response to MEK and AKT inhibitors in KRAS mutant lung adenocarcinoma (adeno-NSCLC). PD-L1 expression was quantified using immunofluorescence and co-culture with a jurkat cell-line transfected ...
Genomic Determinants of Protein Abundance Variation in Colorectal Cancer Cells.
(CELL PRESS, 2017-08-29)
Assessing the impact of genomic alterations on protein networks is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labeling to characterize the proteomic landscapes of 50 ...
