  2. 1. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function

    Author : Charlotte Öberg-Welsh; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinase; insulin producing cells; fetal development; VEGF; Src-family; Bsk; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. READ MORE

  4. 2. Protein Tyrosine Phosphatases as Regulators of Receptor Ryrosine Kinases

    Author : Camilla Persson; Arne Östman; Niels Peter Moller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; protein tyrosine phosphatase; tyrosine kinase; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Tyrosine phosphorylation is a crucial mechanism in cellular signaling and regulates proliferation, differentiation, migration and adhesion. The phosphorylation reaction is reversible and is governed by two families of enzymes: protein tyrosine kinases and protein tyrosine phosphatases (PTPs). READ MORE

  5. 3. Protein tyrosine kinases and the regulation of signalling and adhesion in drosophila melanogaster

    Author : Caroline Grabbe; Ruth Palmer; Tapio Heino; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Drosophila; Signalling; Adhesion; Protein Tyrosine Kinase; Development; Endocytosis; Molecular biology; Molekylärbiologi;

    Abstract : In order to build a multi-cellular organism and to regulate cellular functions, cells need to communicate with each other, as well as tightly regulate their behaviour in response to environmental changes. For these purposes all eukaryotic cells express a large number of membrane spanning receptors that either themselves contain catalytic activity or via cytoplasmic effector enzymes, function to transmit “signals” from the cell exterior to induce appropriate responses within the cell.

  6. 4. T-Cell Protein Tyrosine Phosphatase, a Regulator of the PDGF Signaling Pathway

    Author : Susann Karlsson; Carina Hellberg; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; TC-PTP; receptor trafficking; PK-M2; Medical cell biology; Medicinsk cellbiologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Platelet-derived growth factor (PDGF) is a potent stimulator of cell growth, survival and motility. PDGF exerts its function by binding to specific tyrosine kinase receptors, initiating receptor auotphosphorylation and initiation of specific signaling pathways that regulates the cellular response.

  7. 5. The receptor tyrosine kinase Met and the protein tyrosine phosphatase PTPN2 in breast cancer

    Author : Cynthia Veenstra; Olle Stål; Gizeh Perez-Tenorio; Pietras Kristian; Linköpings universitet; []
