  1. 21. Fat cell insulin resistance : an experimental study focusing on molecular mechanisms in type 2 diabetes

    Författare :Frida Renström; Jan Eriksson; Anna Krook; Umeå universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adipocyte; insulin signaling; insulin; glucose; IRS-1; glucose uptake; insulin resistance; typ 2 diabetes; serum; Medicine; Medicin;

    Sammanfattning : The aim of the present thesis was to further increase our understanding of mechanisms contributing to and maintaining cellular insulin resistance in type 2 diabetes (T2D). For this reason, the effects of high glucose and insulin levels on glucose transport capacity and insulin signaling, with emphasis on insulin receptor substrate 1 (IRS-1) were assessed in fat cells.

  3. 22. Search for Type 2 Diabetes Susceptibility Genes Using Multiple Approaches

    Författare :Cecilia Lindgren; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single nucleotide polymorphism SNP ; transmission-disequilibrium test TDT ; genetic variation; single strand conformational polymorphism SSCP ; gene expression; insulin; glucose; genome-wide scan; linkage; genetic association; Type 2 diabetes; early onset diabetes EOD ; sekretion; diabetologi; Endokrinologi; diabetology; Endocrinology; secreting systems; signal-to-noise ratio SNR ;

    Sammanfattning : Type 2 diabetes mellitus is a multifactorial disorder characterized by chronic hyperglycemia resulting from pancreatic dysfunction and insulin resistance. It is a common disorder with a complex pattern of inheritance, likely to reflect the influence of multiple genetic and environmental factors on the diabetes risk. LÄS MER

  4. 23. Exocytosis in Type 2 Diabetes- Functional and genetic studies of hormone secretion

    Författare :Sofia A Andersson; Diabetes - öcellsexocytos; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Type 2 Diabetes; Insulin; Glucagon; Alpha-cells; Beta-cells; Exocytosis; Capacitance; SNARE; SNAP25; Syntaxin1A; Synaptotagmin; Munc-18 Stxbp1 ; SNP; Expression; miRNA;

    Sammanfattning : Type 2 Diabetes (T2D) is characterized by dysregulated beta-and alpha-cell hormone secretion leading to elevated blood glucose levels. Several proteins are crucial in maintaining exocytosis of the hormone-containing granules such as Syntaxin1A (Stx1A), SNAP25, Munc-18 (Stxbp1) and the family of Synaptotagmins (Syts). LÄS MER

  5. 24. The role of CART in islet function

    Författare :Mia Abels; Neuroendokrin cellbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cocaine- and amphetamine-regulated transcript; CART; Diabetes; T2D; Human islets; Glucagon; Insulin; Adipocyte;

    Sammanfattning : Diminished insulin secretion and dysregulated glucagon secretion are key features of type 2 diabetes (T2D). The overall aim of this thesis was to study the role of cocaine- and amphetamine-regulated transcript (CART) in islet cell function and how CART regulates glucose homeostasis. LÄS MER

  7. 25. Physiology and Pathophysiology of Hormone Secretion from lslets of Langerhans

    Författare :Samuel Acreman; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Islet; diabetes; glucagon; insulin; somatostatin; incretin; pancreas; hypoglycaemia; tetraspanin; GLP-1; endoplasmic reticulum;

    Sammanfattning : Diabetes is a metabolic disorder stemming from the improper regulation of blood glucose levels by hormones secreted by pancreatic islets of Langerhans. Paper I describes the mechanism by which glucose can regulate glucagon secretion, independent of membrane potential, from pancreatic α-cells, via modulation of endoplasmic reticulum Ca2+ handling.
