  2. 1. Glucose and lipid metabolism in insulin resistance : an experimental study in fat cells

    Author : Jonas Burén; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; adipocyte; insulin resistance; type 2 diabetes; insulin signalling; glucose uptake; insulin; glucose; dexamethasone; insulin receptor substrate; protein kinase B; GLUT4; lipoprotein lipase; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden; medicin; Medicine;

    Abstract : Type 2 diabetes is usually caused by a combination of pancreatic β-cell failure and insulin resistance in target tissues like liver, muscle and fat. Insulin resistance is characterised by an impaired effect of insulin to reduce hepatic glucose production and to promote glucose uptake in peripheral tissues. 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

    Author : Martin Ridderstråle; Diabetes - klinisk obesitasforskning; []
    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. Interplay between hormones, nutrients and adipose depots in the regulation of insulin sensitivity : an experimental study in rat and human adipocytes

    Author : Magdalena Lundgren; Jan Eriksson; Jonas Burén; Eva Degerman; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipose tissue; cAMP; glucocorticoids; glucose; insulin; insulin resistance; lipolysis; subcutaneous fat; type 2 diabetes; visceral fat; Medicine; Medicin;

    Abstract : Obesity and specifically central obesity is related to insulin resistance, type 2 diabetes and other components of the so-called metabolic syndrome. The aim of this study was to elucidate the interplay between hormones, nutrients and adipose depots in normal and insulin-resistant fat cell metabolism. READ MORE

  7. 5. Insulin signaling and glucose transport in insulin resistant human skeletal muscle

    Author : Håkan K R Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Skeletal muscle; insulin resistance; type 2 diabetes; glucose transport; insulin signaling; first-degree relatives; AS160; SelS; rosiglitazone treatment;

    Abstract : Insulin resistance in skeletal muscle is a hallmark feature of Type 2 diabetes mellitus. The overall aim of this thesis was to investigate downstream intermediates in the insulin signaling pathway in an attempt to characterize the molecular mechanism of skeletal muscle insulin resistance in Type 2 diabetes.
