1. Myxine insulin : amino-acid sequence, three dimensional structure, biosynthesis, release, physiological role, receptor binding affinity, and biological activity
Sammanfattning : The Atlantic hagfish, Myxlne. glutinosa,is the most primitive vertebrate extant, and it diverged from the main vertebrate evolutionary chain some 500 mi 11 ion years ago. LÄS MER
2. 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
3. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture
Sammanfattning : The yeast Saccharomyces cerevisiae has widely been used as a host for the production of heterologous proteins. High-level production of heterologous proteins is likely to impose a metabolic burden on the host cell and can thus affect various aspects of cellular physiology. LÄS MER
4. Membrane lipids and their transfer proteins in β-cells
Sammanfattning : Insulin secretion from β-cells is essential for glucose homeostasis and is often dysregulated in diabetes. Intracellular Ca2+ and membrane lipids cooperate to control insulin secretion with high spatial and temporal precision. LÄS MER
5. Studies of cAMP and Ca2+ signaling in pancreatic islet cells
Sammanfattning : The blood glucose-lowering and -elevating hormones insulin and glucagon are released from the pancreatic islet β- and α-cells, respectively. The intracellular messengers Ca2+ and cAMP have central roles in controlling the secretion of both hormones, but the underlying mechanisms are incompletely understood. LÄS MER
