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 ...
The Lineage Determining Factor GRHL2 Collaborates with FOXA1 to Establish a Targetable Pathway in Endocrine Therapy-Resistant Breast Cancer.
(CELL PRESS, 2019-10-22)
Notwithstanding the positive clinical impact of endocrine therapies in estrogen receptor-alpha (ERα)-positive breast cancer, de novo and acquired resistance limits the therapeutic lifespan of existing drugs. Taking the ...
The secreted protease Adamts18 links hormone action to activation of the mammary stem cell niche.
(NATURE PUBLISHING GROUP, 2020-03-26)
Estrogens and progesterone control breast development and carcinogenesis via their cognate receptors expressed in a subset of luminal cells in the mammary epithelium. How they control the extracellular matrix, important ...
Intraductal patient-derived xenografts of estrogen receptor α-positive breast cancer recapitulate the histopathological spectrum and metastatic potential of human lesions.
(WILEY, 2019-03-01)
Estrogen receptor α-positive (ER-positive) or 'luminal' breast cancers were notoriously difficult to establish as patient-derived xenografts (PDXs). We and others recently demonstrated that the microenvironment is critical ...
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 ...
Ubiquitin-Mediated Regulation of RIPK1 Kinase Activity Independent of IKK and MK2.
(CELL PRESS, 2018-02-15)
Tumor necrosis factor (TNF) can drive inflammation, cell survival, and death. While ubiquitylation-, phosphorylation-, and nuclear factor κB (NF-κB)-dependent checkpoints suppress the cytotoxic potential of TNF, it remains ...
Targeting the Vulnerability of RB Tumor Suppressor Loss in Triple-Negative Breast Cancer.
(CELL PRESS, 2018-01-30)
Approximately 30% of triple-negative breast cancers (TNBCs) exhibit functional loss of the RB tumor suppressor, suggesting a target for precision intervention. Here, we use drug screens to identify agents specifically ...
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 ...
Checkpoints in TNF-Induced Cell Death: Implications in Inflammation and Cancer.
(ELSEVIER SCI LTD, 2018-01-01)
Tumor necrosis factor (TNF) is a proinflammatory cytokine that coordinates tissue homeostasis by regulating cytokine production, cell survival, and cell death. However, how life and death decisions are made in response to ...
Chemotherapy-induced senescent cancer cells engulf other cells to enhance their survival.
(ROCKEFELLER UNIV PRESS, 2019-11-04)
In chemotherapy-treated breast cancer, wild-type p53 preferentially induces senescence over apoptosis, resulting in a persisting cell population constituting residual disease that drives relapse and poor patient survival ...
