11. Mechanisms of insulin signaling and the role of caveolae
Sammanfattning : Insulin regulates metabolic as well as mitogenic processes in target cells, involving a large number of mediators of signal transduction. In its role as a growth factor, insulin stimulates cell growth, in a process we demonstrate requires the participation of the Raf-1 kinase. LÄS MER
12. Caveolae in insulin signalling in human and rat adipocytes
Sammanfattning : The pancreatic hormone insulin is a key hormone in maintenance of metabolic homeostasis but it also exerts control on gene expression and cell growth. This thesis presents results on fhe role of caveolae in insulin signalling in human and rat adipocytes. LÄS MER
13. Caveolae structure and importance in insulin action
Sammanfattning : Type II diabetes is a disease characterized by chronic hyperglycaemia and abnormalities in lipid metabolism that affects approximately 5% of the population in the Western World. Caveolae are invaginations of the plasma membrane, described as 25-150 nm omega shaped structures, which are enriched in cholesterol, sphingolipids and the constituent protein caveolin. LÄS MER
14. Cyclic AMP Oscillations in Insulin-Secreting Cells
Sammanfattning : Cyclic AMP is an intracellular messenger that regulates numerous processes in various types of cells. In pancreatic β-cells, cAMP potentiates the secretion of insulin by promoting Ca2+ signals and by amplifying Ca2+-triggered exocytosis. Whereas Ca2+ signals have been extensively characterized, little is known about the kinetics of cAMP signals. LÄS MER
15. Interleukin-6 as a mediator of insulin resistance
Sammanfattning : A potential role of interleukin (IL)-6 for the metabolic abnormalities seen in obesity and insulinresistance was postulated when it was discovered that circulating IL-6 levels were elevated in obeseand insulin-resistant as well as type 2 diabetic individuals. Later it was shown that the adipose tissuewas a major site of IL-6 production, accounting for 15-35% of the total circulating levels. LÄS MER
