  4. 2. Hormonal regulation of phosphodiesterase 3B in adipocytes

    Author : Rebecka Lindh; Signaltransduktionsforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; secreting systems; diabetology; Endokrinologi; Endocrinology; caveolae localization ; phosphorylation interactions ; PDE3B adipocyte adipose tissue diabetes cAMP insulin ; lipolysis caveolin-1 ; sekretion; diabetologi;

    Abstract : Insulin induced activation of the cAMP degrading enzyme phosphodiesterase (PDE) 3B in adipocytes is important for insulin mediated inhibition of lipolysis. The aim of this thesis was to contribute with knowledge on the acute activation of PDE3B in response to insulin and catecholamines in adipocytes. READ MORE

  5. 3. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells

    Author : Tova Landström; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3T3-L1 TNF-alpha; adipocyte; insulin; p70S6 kinase; mitogen-activated protein kinase; protein kinase B; phosphatidylinositol-3 kinase; phosphodiesterase 3B; cAMP; lipolysis; phosphorylation; signal transduction; Biochemistry; Metabolism; Biokemi; metabolism;

    Abstract : Insulin stimulation of rat adipocytes results in phosphorylation and activation of the cyclic nucleotide phosphodiesterase 3B (PDE3B), a key enzyme in the antilipolytic signalling pathway of this hormone. In this thesis, the site phosphorylated in PDE3B upon stimulation of rat adipocytes with insulin and/or the beta-adrenergic agonist, isoproterenol is identified. READ MORE

  6. 4. Regulation of lipid metabolism in rat and 3T3-L1 adipocytes; Cross-talk between Insulin, the neuro-peptides PACAP/VIP and with B1-integrins

    Author : Lina Åkesson; Celiaki och diabetes; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; Endokrinologi; sekretion; diabetologi; secreting systems; Endocrinology; obesity; Insulin; diabetes;

    Abstract : Type 2 Diabetes is a disorder that increases globally, but mainly in the western world. One of the hallmarks of Type 2 diabetes is insulin resistance in the target tissues of insulin action (adipose tissue, liver and skeletal muscle). In addition, most patients with Type 2 diabetes are obese. READ MORE

  7. 5. Hormone-Sensitive Lipase and Protein Kinase B; Molecular characterization in testis, adipose tissue and pancreatic beta cells

    Author : Lena Stenson; Signaltransduktionsforskning; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; pancreas; beta cells; adipocyte; insulin; Akt; protein kinase B; spermatogenesis; cholesterol esterase; hormone-sensitive lipase; testis; cAMP; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : Hormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin and growth factors.
