  2. 1. Protein kinases in hormonal regulation of adipocyte metabolism

    Author : Christine Berggreen; Proteinfosforylering; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adipocyte; PKB; AMPK; SIK3; insulin; catecholamines; lipolysis; lipogenesis; glucose uptake; de novo fatty acid synthesis; A769662; Akti; cAMP;

    Abstract : Abstract Along with liver and muscle tissue, adipose tissue helps maintain normal levels of glucose and lipids in the blood and has a very important role when it comes to storing lipids that can provide whole-body energy. After a meal is ingested, adipocytes take up glucose from the circulation and use it as a substrate for synthesis of new fatty acids (FAs) in a process known as de novo fatty acid synthesis, as well as for synthesis of glycerol.

  4. 2. The role of phosphodiesterase 3B in energy metabolism

    Author : Emilia Zmuda-Trzebiatowska; Signaltransduktionsforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; Physiology; Fysiologi; Medicin människa och djur ; glucose uptake; lipogenesis; adipocyte; Medicine human and vertebrates ; cAMP; PDE3B; insulin; Endokrinologi; sekretion; diabetologi;

    Abstract : Energy metabolism at the level of any particular tissue is tightly regulated by hormones, neurotransmitters and cytokines in order to maintain overall energy homeostasis. Any dysfunctions in energy metabolism may lead to more or less severe consequences, with obesity and type 2 diabetes being the most prevalent ones. 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. Effects of immunosuppressive drugs on human adipose tissue metabolism

    Author : Maria J Pereira; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cyclosporin A; tacrolimus; rapamycin; glucocorticoids; new onset diabetes after transplantation; adipocytes; insulin signalling; glucose uptake; lipolysis; lipogenesis;

    Abstract : The immunosuppressive agents (IAs) rapamycin, cyclosporin A and tacrolimus, as well as glucocorticoids are used to prevent rejection of transplanted organs and to treat autoimmune disorders. Despite their desired action on the immune system, these agents have serious long-term metabolic side-effects, including dyslipidemia and new onset diabetes mellitus after transplantation. READ MORE

  7. 5. Studies on fat cell function in human obesity and insulin resistance

    Author : Patrik Löfgren; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Fat cell; lipolysis; lipogenesis; leptin; obesity; perilipin; polymorphism; post-obese; TNF-alpha; weightreduction.;

    Abstract : Enlarged fat cells, due to excess tri-glyceride (TG) stores with increased basal lipolysis (TG breakdown) and blunted action of the major regulatory hormones of fat cell metabolism (catecholamines and insulin) are hallmarks of common obesity in humans. It is, however, not known whether these aberrations are caused by obesity per se or is a consequence of obesity. READ MORE
