MCF10A-HER2/3 cells grown in 3D cultures in the presence or absence of SHP2

ABSTRACT: The first bona fide PTP proto-oncogene was the Src-homology 2 domain-containing phosphatase SHP2 (encoded by PTPN11), an ubiquitously expressed PTP that transduces mitogenic, pro-survival, cell fate and/or pro-migratory signals from numerous growth factor-, cytokine- and extracellular matrix receptors. In malignancies, SHP2 is hyperactivated either downstream of oncoproteins or by mutations.We provide analysis of the mammary epithelial cells MCF10A overexpressing human HER2 and HER3 and grown in 3D cultures for 15 days in the presence or absence of SHP2. The human mammary epithelial cells MCF10A were transduced with a doxycycline-inducible lentiviral vector expressing a CTRL miR or SHP2 miR1 or SHP2 miR2. Cells from each group were grown in 3D cultures, and the knockdown of SHP2 was induced for 15 days. RNA was extracted for gene expression analysis.

MCF10A cells expressing HER2 and HER3 and grown in three-dimensional cultures

Project description:The tyrosine kinase receptors HER2 and HER3 play an important role in breast cancer. The HER2/HER3 heterodimer is a critical oncogenic unit associated with reduced relapse-free and decreased overall survival. We provide gene expression profile of the mammary epithelial cells MCF10A expressing HER2, HER3 or HER2/HER3 and grown in three-dimensional cultures for 15 days in the presence of heregulin, a known HER3-ligand that stabilizes and activates the HER2/HER3 heterodimer. The mammary epithelial cells MCF10A were transduced with retroviral vectors expressing HER2, HER3 or both. Cells from each group were grown for 15 days in three-dimensional cultures. At the end of the experiment, RNA was extracted for gene expression analysis.

Cells from each group were injected in imuunodeficinet mice and after tumor development, the knockdown of SHP2 was induced for 30 days in vivo. At day 30, tumors were dissected and RNA isolated for gene expression analysis.

Expression profiling of MCF10A cells in 2D and 3D culture

Project description:In these microarray experiments, we characterize the gene expression of mammary epithelial cells (MCF10A cells) grown in either a traditional monolayer cell culture setting (2D) or on Matrigel, which induces single MCF10A cells to form organized acinar structures (3D). Morphogenesis of mammary epithelial cells into organized acinar structures in vitro is accompanied by widespread changes in gene expression patterns, including a substantial decrease in expression of Myc. The purpose of this study was to analyze the impact of morphogenesis and organization on gene expression with respect to changes in overall gene expression and Myc target gene expression. MCF10A cells were cultured in 2D for either 2 or 5 days (3 biological replicates each) or in 3D for 8 or 16 days (3 or 5 biological replicates, respectively)

Shp2 Signaling Suppresses Senescence in PyMT-induced Mammary Gland Cancer in Mice [Mouse430A_2 array]

Project description:In this study, we have used techniques from cell biology, biochemistry, and genetics to investigate the role of the tyrosine phosphatase Shp2 in tumor cells of MMTV-PyMT mouse mammary glands. Genetic ablation or pharmacological inhibition of Shp2 induces senescence, as determined by the activation of senescence-associated β-gal (SA-β-gal), cyclin-dependent kinase inhibitor 1B (p27), p53, and histone 3 trimethylated lysine 9 (H3K9me3). Senescence induction leads to inhibition of self-renewal of tumor cells and blockage of tumor formation and growth. A signaling cascade was identified that acts downstream of Shp2 to counter senescence: Src, Focal adhesion kinase and Map kinase inhibit senescence by activating the expression of S-phase kinase-associated protein 2 (Skp2), Aurora kinase A (Aurka), and the Notch ligand Delta-like 1 (Dll1), which block p27 and p53. Remarkably, the expression of Shp2 and of selected target genes predicts human breast cancer outcome. We conclude that therapies which rely on senescence induction by inhibiting Shp2 or controlling its target gene products may be useful in blocking breast cancer. For Shp2 ablation, primary mammary tumor cells from MMTV-PyMT;Shp2fl/fl mice were transduced with retroviruses expressing control GFP or CreERT2-GFP, and GFP-positive cells were purified by FACS and cultured as mammospheres for 1 week. Mammospheres were then treated with 50 nM 4-OHT for 2 hours, cultured for another 5 days, and subjected to RNA isolation. For pharmacological inhibition, primary mammary tumor cells from the same mice were cultured as mammospheres for 10 days and then treated with the Shp2 inhibitor GS493 for another 2 days. Mammospheres were then subjected to RNA isolation. Each group contains 3 replicates.

Systematic Identification of SHP2 Phosphatase Substrates

Project description:Phosphatases play essential roles in normal cell physiology and diseases like cancer. The challenges of studying phosphatases have limited our understanding of their substrates, molecular mechanisms, and unique functions within highly complicate networks. Here we introduce a novel strategy using substrate trapping mutant coupled with quantitative mass spectrometry to identify physiological substrates of protein tyrosine phosphatase Src homology 2 containing protein tyrosine phosphatase 2 (SHP2) in a high-throughput manner. SHP2 plays a critical role in numerous cellular processes through the regulation of various signaling pathways. The method integrates three separate MS-based experiments; in vitro dephosphorylation assay, in vivo global phosphoproteomics, and pull down of substrate trapping mutant complex using HEK293SHP2KO cells. PTPN11-C459S/D425A is an optimized substrate trap mutant of SHP2. We identified eleven direct substrates, including both known and novel SHP2 substrates in EGFR signaling pathways, among which docking protein 1 (DOK1) was further validated as a new SHP2 substrate. This advanced workflow significantly improves the systemic identification of direct substrates of phosphatase, facilitating the comprehension of equally important roles of phosphatase signaling.
