  2. 1. Roles of PI3-kinase and ARAP2 in regulating glucose metabolism

    Author : Aditi Chaudhari; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PI3-kinase; Type 2 diabetes; ARAP2; Lipid droplets; metabolism;

    Abstract : Insulin signaling is mediated by a complex, highly integrated network which functions to control multiple metabolic and growth processes throughout the organism. A key enzyme in the insulin signaling network is phosphatidylinositol 3-kinase (PI3-kinase). READ MORE

  4. 2. Regulation of intracellular signaling events that modulate insulin action

    Author : Silvia Gogg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; insulin; insulin resistance; EGF; Gab 1; insulin receptor substrate; PI3-kinase; ; Thiazolidinediones; PPARã; insulin signaling; glucose transport; adipose tissue; â-cell.;

    Abstract : Insulin regulates several mechanisms of fundamental importance to the body involving glucose, fat andprotein metabolism. Insulin resistance in skeletal muscle, liver and adipose tissue promotes an increaseddemand for insulin secretion. READ MORE

  5. 3. 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

    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Stem Cell Factor Induced Signal Transduction

    Author : Johan Lennartsson; Christer Larsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

    Abstract : Stem Cell Factor (SCF) can function as a survival factor, a mitogen or a chemoattractant depending on cell type. Binding of SCF to c-Kit induces dimerization and subsequent autophosphorylation of the receptor. This thesis describes the intracellular signal transduction elicited by c-Kit. READ MORE

  7. 5. Uncoupling Proteins : Regulation by IGF-1 and Neuroprotection during Hyperglycemia in Vitro

    Author : Helena Gustafsson; Anna Forsby; David Tomlinson; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; uncoupling protein; oxidative stress; diabetes; neuropathy; SH-SY5Y; Neurobiology; Neurobiologi;

    Abstract : Diabetic neuropathy is believed to arise due to oxidative stress following hyperglycemic situations. Uncoupling proteins (UCPs) constitute a subgroup of mitochondrial transporter proteins with putative antioxidant properties. READ MORE
