Project description:1205Lu Metastatic Human melanoma cell lines with knockdown of Shp2 (PTPN11) were grown as xenograft tumors in NSG mice. RNA was extracted from the tumors and analyzed on [HuGene-2_0-st] Affymetrix Human Gene 2.0 ST Array [transcript (gene) version] Shp2 knockdown compared with non-target controls

Project description: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 breast cancer cells BT474 grown as xenografts in the presence or absence of SHP2 for 30 days. The HER2-postive breast cancer cell line BT474 was transduced with a doxycycline-inducible lentiviral vector expressing a CTRL miR or SHP2 miR1 or SHP2 miR2. 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.

In malignancies, SHP2 is hyperactivated either downstream of oncoproteins or by mutations.We provide analysis of a primary triple-negative breast tumor grown as xenografts in the presence or absence of SHP2 for 30 days. A primary triple-negative breast tumor (BT8) was transduced with a doxycycline-inducible lentiviral vector expressing a CTRL miR or SHP2 miR1 or SHP2 miR2. Cells from each group were injected in immunodeficient mice and after tumor development, the knockdown of SHP2 was induced for 30 days in vivo.

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.

Project description:The equilibrium between proliferation and quiescence of myogenic progenitor and stem cells is tightly regulated to ensure appropriate muscle growth and repair. The non-receptor tyrosine phosphatase Shp2 (Ptpn11) is an important transducer of growth factor and cytokine signaling. Here we combined complex genetic analyses, biochemical studies and pharmacological interference to demonstrate a central role of Shp2 in postnatal myogenesis of mice. Loss of Shp2 drove muscle stem cells into quiescence during postnatal muscle growth and repair and thus interfered with myogenesis in a drastic manner. This Shp2 function was observed in postnatal but not fetal myogenic stem cells. Thus, we provide evidence for an unexpected molecular difference in the control of proliferation and cell cycle withdrawal in fetal and postnatal myogenic stem cells.
