1. Glucose and lipid metabolism in insulin resistance : an experimental study in fat cells
Sammanfattning : 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. LÄS MER
2. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells
Sammanfattning : 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. LÄS MER
3. Selenoproteins in the Bovine Mammary Gland. Regulation of mRNA and Protein Expression
Sammanfattning : Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. LÄS MER
4. Regulation of intracellular signaling events that modulate insulin action
Sammanfattning : 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. LÄS MER
5. Links between plasma apoE and glucose metabolism, brain insulin signaling, and synaptic integrity : Relevance to Alzheimer’s disease pathophysiology
Sammanfattning : Human apolipoprotein E (apoE) exists as three main isoforms called apoE2, apoE3, and apoE4, of which the E4 isoform is associated with increased Alzheimer’s disease (AD) risk. Brain glucose hypometabolism, linked to synaptic dysfunction, occurs years before symptom onset in AD, especially in APOEε4-carriers. LÄS MER
