  1. 16. Calcium and Phospholipases in Orexin Receptor Signaling

    Författare :Lisa Johansson; Jyrki Kukkonen; Karl Åkerman; Christopher S. Leonard; Uppsala universitet; []
    Nyckelord :Physiology; orexin; receptor; calcium; phospholipase; cell signaling; GPCR; Fysiologi;

    Sammanfattning : The neuropeptides orexin-A and -B act as endogenous ligands for G-protein-coupled receptors (GPCRs) called OX1 and OX2 receptors. Previous observations have established that orexin receptors have an ability to couple to different G-proteins and signaling pathways and induce Ca2+ elevations via both receptor-operated Ca2+ channels (ROCs) and store-operated Ca2+ channels (SOCs).

  3. 17. Signaling capacity of ß2-integrins in relations to neutrophil motility

    Författare :Ragnhild Löfgren; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Sammanfattning : The neutrophil granulocyte is one of the most mobile cell types in the human body and represents the first line of defense against invading pathogens. Adhesion and chemotactic receptors on the cell surface work together through modulations of the cytoskeleton and thereby cause the cell to move. LÄS MER

  4. 18. Insulin resistance in pancreatic cancer

    Författare :Bengt Isaksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pancreatic cancer; glucose transport; glucose metabolism; insulin signaling; insulin resistance; uncoupling proteins; obstructive jaundice; IAPP; risk factors.;

    Sammanfattning : The dismal prognosis of pancreatic cancer (PC) is related to metabolic complications of the tumor. Impaired glucose tolerance or diabetes due to insulin resistance, and cachexia are observed early and frequently in these patients. The basic mechanisms of PC-associated insulin resistance and weight loss are not fully understood. LÄS MER

  5. 19. Hormone-Sensitive Lipase and Protein Kinase B; Molecular characterization in testis, adipose tissue and pancreatic beta cells

    Författare :Lena Stenson; Signaltransduktionsforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; signal transduction; pancreas; beta cells; adipocyte; insulin; Akt; protein kinase B; spermatogenesis; cholesterol esterase; hormone-sensitive lipase; testis; cAMP; Proteins; enzymology; Proteiner; enzymologi;

    Sammanfattning : Hormone-sensitive lipase (HSL) and protein kinase B (PKB) are enzymes that in different ways are associated with lipid metabolism. While HSL is the well-known lipolytic enzyme responsible for hydrolysis of stored triacylglycerols in adipose tissue, PKB is a recently identified serine/threonine protein kinase, ubiquitously expressed and involved in signal transduction pathways induced by insulin and growth factors.

  7. 20. Roles of PI3-kinase and ARAP2 in regulating glucose metabolism

    Författare :Aditi Chaudhari; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PI3-kinase; Type 2 diabetes; ARAP2; Lipid droplets; metabolism;

    Sammanfattning : Insulin signaling is mediated by a complex, highly integrated network which functions to control multiple metabolic and growth processes throughout the organism. A key enzyme in the insulin signaling network is phosphatidylinositol 3-kinase (PI3-kinase). LÄS MER
