  3. 7. Evolution and Pharmacology of Neuropeptide Y Receptors, Implications for vertebrate genome duplications

    Författare :Robert Fredriksson; Susanne Holmgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Evolution; tetraploidizations; G-protein coupled receptor; neuropeptide Y; zebrafish; chicken; rainbow trout; lamprey; genome duplications; peptide YY; pancreatic polypeptide; Neurovetenskap; Neurology; Neurologi; medicinsk farmakologi; Medical Pharmacology;

    Sammanfattning : The Y receptors comprise a family of evolutionarily related receptors belonging to the superfamily of G-protein coupled receptors (GPCR). Their natural ligands are in mammals neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER

  4. 8. Evolution of the Neuropeptide Y System in Vertebrates with Focus on Fishes

    Författare :Tomas Larsson; Dan Larhammar; Svante Winberg; Kenneth H. Wolfe; Uppsala universitet; []
    Nyckelord :Molecular biology; neuropeptide Y; GPCR; evolution; gene duplication; vertebrates; ray-finned fishes; Molekylärbiologi;

    Sammanfattning : Gene families in vertebrates often contain more dulicates (paralogs) than in invertebrates. This has been attributed to genome duplications, i.e., tetraploidizations. LÄS MER

  5. 9. Evolution of the Neuropeptide Y and Opioid Systems and their Genomic Regions

    Författare :Görel Sundström; Dan Larhammar; Manfred Schartl; Uppsala universitet; []
    Nyckelord :neuropeptide Y; opioid; evolution; genome duplication; gene duplication; Hox; SCN; IGFBP; MEDICINE; MEDICIN;

    Sammanfattning : Two whole genome duplications (2R) occurred early in vertebrate evolution. By using combined information from phylogenetic analyses and chromosomal location of genes, this thesis delineates the evolutionary history of two receptor-ligand systems that expanded by these large scale events.

  7. 10. Expression and Regulation of Neuropeptide Y (NPY) in the Islets of Langerhans

    Författare :Ulrika Myrsén Axcrona; Neuroendokrin cellbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocrinology; regulatory peptides; diabetes; glucocorticoids; beta cell; islet hormones; neuropeptide Y; insulin; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Sammanfattning : This thesis deals with the expression, localization and regulation of neuropeptide Y (NPY) in the pancreatic islets of Langerhans under normal and experimental conditions. NPY is widely distributed in the mammalian nervous system and belongs to a family of closely related petides also comprising peptide YY (PYY) and pancreatic polypeptide (PP). LÄS MER
