  1. 1. Myxine insulin : amino-acid sequence, three dimensional structure, biosynthesis, release, physiological role, receptor binding affinity, and biological activity

    Författare :Stefan O. Emdin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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. 2. Links between plasma apoE and glucose metabolism, brain insulin signaling, and synaptic integrity : Relevance to Alzheimer’s disease pathophysiology

    Författare :Anna Edlund; Henrietta Nielsen; William Rebeck; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; apolipoprotein E; insulin; metabolism; Amyloid precursor protein APP ; Fe65; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    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. 3. Physiology of Saccharomyces cerevisiae Producing Recombinant Insulin in Continuous Culture

    Författare :Ali Kazemi Seresht; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unfolded protein response; Keywords: heterologous protein production; prolonged chemostat; transcriptome; insulin analogue precursor; metabolic adaptation; URA3d; plasmid copy number; promoter truncation; high cell density cultivation; TPI1;

    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. 4. Membrane lipids and their transfer proteins in β-cells

    Författare :Beichen Xie; Olof Idevall-Hagren; Anders Tengholm; Jen Liou; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ca2 ; PKC; E-Syt1; TMEM24; ER-PM contact; PI 4; 5 P2; phosphoinositides; β-cell; insulin; optogenetics; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    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. 5. Studies of cAMP and Ca2+ signaling in pancreatic islet cells

    Författare :Hongyan Shuai; Anders Tengholm; Erik Gylfe; Sebastian Barg; Albert Salehi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pancreatic islet; insulin; glucagon; somatostatin; pancreatic polypeptide; exendin- 9-39 ; GLP-1; GIP; ATP; adenosine; cAMP; Ca2 ; β-cell; α-cell; δ-cell; PP-cell;

    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
