31. Expression of Islet Amyloid Polypeptide - Localization and regulation in the pancreatic islets, gastrointestinal tract and sensory nervous system
Sammanfattning : Islet amyloid polypeptide (IAPP; also named ”amylin”) is a member of the calcitonin superfamily of peptides, displaying the closest structural relationship to the neuropeptide calcitonin gene-related peptide (CGRP). It is expressed in islet beta-cells and forms islet amyloid in type 2 diabetic patients. LÄS MER
32. Signal transduction and calcium sensitivity of smooth muscle contraction
Sammanfattning : Smooth muscles are components of several physiologically important organs and often involved in disease. Smooth muscle contraction is regulated by variations in intracellular [Ca2+]; increased levels activate the myosin light chain kinase (MLCK) which phosphorylates myosin and initiates contraction.

33. Discovery of Novel Receptors for Lipid Mediators - a study leading to the identification of receptors involved in metabolism and the immune system
Sammanfattning : Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. LÄS MER
34. Structure and function of the cytoskeleton in cardiac and skeletal muscle
Sammanfattning : We have examined the functional and structural roles of the cytoskeletal protein desmin in cardiac and skeletal muscles using a genetically modified mouse (Des-/-) with the desmin gene ablated. Desmin forms filaments at the Z-disks in the striated muscle sarcomere, have connections to the sarcolemma and most likely align sarcomeres and whole cells. LÄS MER
35. Cyclic Nucleotide Phosphodiesterase 3B: Regulation in rat adipocytes and 3T3-L1 cells
Sammanfattning : Insulin stimulation of rat adipocytes results in phosphorylation and activation of the cyclic nucleotide phosphodiesterase 3B (PDE3B), a key enzyme in the antilipolytic signalling pathway of this hormone. In this thesis, the site phosphorylated in PDE3B upon stimulation of rat adipocytes with insulin and/or the beta-adrenergic agonist, isoproterenol is identified. LÄS MER
