    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

  3. 7. Interplay between hormones, nutrients and adipose depots in the regulation of insulin sensitivity : an experimental study in rat and human adipocytes

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

    Sammanfattning : 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. LÄS MER

  4. 8. Insulin signaling and glucose transport in insulin resistant human skeletal muscle

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

    Sammanfattning : 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.

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; forkhead genes; insulin signaling; glucose metabolism; adipose tissue; angiogenesis; Foxc2; Foxf2; Irs1; insulin resistance; Ang-2;

    Sammanfattning : Type 2 diabetes is the most common metabolic disorder today and has reached epidemic proportions in many countries. Diet-induced insulin resistance plays a central role in the development of type 2 diabetes. LÄS MER

  7. 10. Aspects of Regulation of GFR and Tubular Function in the Diabetic Kidney : Roles of Adenosine, Nitric Oxide and Oxidative Stress

    Författare :Patrik Persson; Fredrik Palm; Peter Hansell; Bengt Rippe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetes; diabetic nephropathy; glomerular filtration rate; renal blood flow; insulin; renal hemodynamics; micropuncture; oxygen; NADPH-oxidase; apocynin; streptozotocin; l-arginine; CGS21680; rats; mice; Physiology; Fysiologi; Medical Science; Medicinsk vetenskap;

    Sammanfattning : Diabetic nephropathy is the main cause for initiation of renal replacement therapy and early symptoms in patients include increased glomerular filtration rate (GFR), decreased oxygen tension and albuminuria, followed by a progressive decline in GFR and loss of kidney function. Experimental models of diabetes display increased GFR, decreased tissue oxygenation and nitric oxide bioavailability. LÄS MER
