  1. 11. Molecular aspects of proinsulin C-peptide interactions

    Författare :Mikael Henriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diabetes mellitus; proinsulin C-peptide;

    Sammanfattning : Insulin biosynthesis in the beta-cells of the pancreas begins with the generation of preproinsulin, which is converted to proinsulin. Proinsulin is cleaved into equimolar amounts of insulin and connecting peptide (C-peptide), which are released into the circulation. LÄS MER

    Sammanfattning : Type 2 diabetes mellitus (T2DM) is a heterogeneous disease with a multifactorial aetiology comprising of genetic and environmental factors. The common variant most highly associated with T2DM known to date is a SNP rs7903146 in the TCF7L2 gene. However, the role TCF7L2 plays in the development of T2DM was unclear. LÄS MER

  4. 13. Molecular Imaging of Diabetic Kidney Tissue and Binding Studies of Proinsulin C-peptide

    Författare :Lina Lindfors; Jan Kihlberg; Ingela Lanekoff; Fredrik Almqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Diabetic kidney disease; Proinsulin C-peptide; GPR146; Mass spectrometry imaging; nano-DESI; Kemi; Chemistry;

    Sammanfattning : Diabetic kidney disease is a serious complication of diabetes with a complex and incompletely understood pathology. In this work, the molecular changes in diabetic rat kidneys at a very early disease stage were studied using nanospray desorption electrospray ionisation mass spectrometry imaging. LÄS MER

  5. 14. Proinsulin C-peptide : membrane interactions and intracellular signaling

    Författare :Zhihui Zhong; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Human renal tubular cell; intracellular signal transduction; ERK1 2; JNK; Na ; K -A TPase; G-protein coupled receptor.;

    Sammanfattning : In the past decade, new evidence has emerged of a physiological role for C-peptide. C-peptide replacement improves renal and nerve function and augments regional blood flow in type I diabetic patients. LÄS MER

  7. 15. Investigations of Strategies to Counteract Proinflammatory Cytokines in Experimental Type 1 Diabetes

    Författare :Andreas Börjesson; Stellan Sandler; Annika Carlsson; Jens Nielsen; Uppsala universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Type 1 diabetes; proinflammatory cytokines; SOCS-3; pancreatic islets; inducible nitric oxide synthase; insulin secretion; NOD mice; islet transplantation; proinsulin conversion; streptozotocin; prolactin; Medicine; Medicin;

    Sammanfattning : Type 1 diabetes (T1D) is a chronic autoimmune disease targeted against the pancreatic β-cells. Proinflammatory cytokines are considered to play a major role in the destruction of the insulin-producing β-cells. This thesis studied strategies to counteract proinflammatory cytokines in experimental T1D. LÄS MER
