  1. 1. The Tyrosine Kinase GTK : Signal Transduction and Biological Function

    Författare :Cecilia Annerén; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinases; GTK; SHB; proliferation; survival; differentiation; β cells; pancreatectomy; cytokines; diabetes; PC12 cells; NGF; streptozotocin; focal adhesion kinase; RAP1; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Protein tyrosine kinases play an important role in the regulation of various cellular processes such asgrowth, differentiation and survival. GTK, a novel SRC-like cytoplasmic tyrosine kinase, was recently cloned from a mouse insulinoma cell line and the present work was conducted in order to find a biological function of GTK in insulin producing and neuronal cells.

  2. 2. Receptors for growth hormone and prolactin. Regulation and activation

    Författare :Gunnel Hellgren; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; GH receptor; Janus kinase; GH sensitivity; 5 -untranslated region; prolactin; prolactin receptor adipose tissue; liver; skeletal muscle; epidermal growth factor receptor; tyrosine kinase; kinase activity;

    Sammanfattning : Cytokine receptor activation is dependent on ligand-induced receptor dimerization or oligomerization and subsequent activation of several intracellular proteins. Activation of Janus kinases (Jaks) is probably the first intracellular event that occurs after receptor dimerization. LÄS MER

  3. 3. Signal Transduction by Proline-Rich Tyrosine Kinase Pyk2

    Författare :Inga Dikic; Olli Silvennoinen; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Protein phosphorylation; tyrosine kinase; Pyk2 FAK; neuronal differentiation; Ras MAP kinase pathway; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : The proline-rich tyrosine kinase (Pyk2) together with focal adhesion kinase (FAK) define a family of non-receptor protein tyrosine kinases that are regulated by diverse stimuli. Activation of Pyk2 has been implicated in multiple signaling events, including modulation of ion channels, activation of MAP kinase cascades and apoptotic cell death. LÄS MER

  4. 4. Molecular Mechanism of Growth Hormone - Involvement of Janus Kinase 2, Insulin Receptor Substrate-1 and -2 and Phosphatidylinositol 3-Kinase In the Acute Insulin-Like Effects of Growth Hormone In Primary Rat Adipocytes

    Författare :Martin Ridderstråle; Diabetes - klinisk obesitasforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin receptor substrate-1; insulin receptor substrate-2 phosphatidylinositol 3-kinase; signal transducer and activator of transcription 5; janus kinase 2; phosphotyrosine; receptor; phosphorylation; Growth hormone; Metabolism; Biochemistry; rat; adipocyte; lipolysis; lipogenesis; Biokemi; metabolism; Pharmacological sciences; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : Originally studying the molecular mechanisms for the insulin-like effects of growth hormone (GH), lipogenesis and antilipolysis, in isolated rat adipocytes we found that the GH receptor (GHR) was tyrosine phosphorylated in response to GH in cells that were responsive to these effects. Then, as Janus kinase 2 (JAK2) was described as a GH-stimulated and GHR-associated tyrosine kinase, we found that JAK2 was tyrosine phosphorylated in response to GH in responsive cells. LÄS MER

  5. 5. Ubiquitination and Receptor Endocytosis

    Författare :Kaisa Haglund; Carl-Henrik Heldin; Ivan Dikic; Harald Stenmark; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Ubiquitination; receptor tyrosine kinase; endocytosis; Cbl; CIN85; EGFR; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : Protein ubiquitination is an evolutionary conserved mechanism that controls a wide variety of cellular functions. Polyubiquitinated proteins are generally degraded in the proteasome, whereas monoubiquitination controls various other cellular processes, including endocytosis and endosomal sorting. LÄS MER
