  2. 1. Cloning, Expression, Pharmacological Characterization and Anatomical Distribution of Melanocortin Receptors in an Evolutionary Perspective

    Author : Aneta I. Ringholm; Helgi B. Schiöth; Dan Larhammar; Björn Olde; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; evolution; melanocortin; MSH; pharmacology; genome duplication; tetraploidization; zebrafish; spiny dogfish; chicken; GPCR; polymorphism; pigmentation; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : The melanocortin (MC) receptors are G-protein coupled receptors thatparticipate in several important physiological functions such as the regulation of the energy balance. This thesis focuses on the evolutionary aspect of the MC receptors and their pharmacology.One MC4 receptor and two MC5 receptor subtypes were found in a teleost fish, zebrafish. READ MORE

  4. 2. Function, Pharmacology, Evolution and Anatomical Localization of G Protein-Coupled Receptors and Solute Carriers

    Author : Tatjana Haitina; Robert Fredriksson; Gert Flik; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; Farmakologi; Medicine; medicin;

    Abstract : The G protein-coupled receptors (GPCRs) and solute carriers (SLC) are two large families of membrane-bound proteins. The aim of this study was to characterize these two families in terms of evolution and function. READ MORE

  5. 3. Molecular Evolution of Neuropeptide Y Receptors in Vertebrates

    Author : Erik Salaneck; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Neuropeptide Y; Receptor; Evolution; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

    Abstract : The three evolutionarily related peptides neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP) are ligands to at least five G-protein coupled receptors in mammals, which are denoted by numbers. NPY has many physiological effects including stimulation of appetite and regulation of circadian rhythm and blood pressure. READ MORE

  6. 4. Basal Vertebrate Divergences from a Molecular Perspective

    Author : Ann-Sofie Rasmussen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mitochondrial genomes; Agnatha; Chondrichthyes; vertebrates; evolution; systematics; Genetics; cytogenetics; Genetik; cytogenetik;

    Abstract : Fishes (Superclass Pisces) constitute the most numerous and morphologically diverse vertebrate group, yet only a small fraction of all molecular evolutionary studies concern piscine evolution. This thesis aims to investigate the vertebrate tree, through the analysis of mitochondrial (mt) DNA sequences. READ MORE
