  1. 1. Somatostatin Receptor Expression and Biological Functions in Endocrine Pancreatic Cells

    Författare :Eva Ludvigsen; Stellan Sandler; Eva Tiensuu Janson; Mats Stridsberg; Frank Sundler; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cell biology; somatostatin; somatostatin receptors; somatostatin analogues; NOD mouse; type 1 diabetes; pancreatic islets; BON-1 cells; Cellbiologi; Cell biology; Cellbiologi;

    Sammanfattning : Type 1 diabetes is resulting from the selective destruction of insulin-producing beta-cells within the pancreatic islets. Somatostatin acts as an inhibitor of hormone secretion through specific receptors (sst1-5). LÄS MER

  3. 2. Theranostics in Neuroendocrine Tumors : Somatostatin Receptor Imaging and Therapy

    Författare :Ezgi Ilan; Mark Lubberink; Peter Bernhardt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-DOTATATE; 68Ga-DOTATATE; 68Ga-DOTATOC; PRRT; Theranostics; PET CT; SPECT CT; Neuroendocrine tumors; Somatostatin receptors; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Neuroendocrine tumors (NETs) are characterized by cellular overexpression of somatostatin receptors (SSTR), which allows for the use of radiolabeled somatostatin analogs (SSA) for both imaging and therapy. Because NETs often are diagnosed at a metastatic stage, curative surgery is not possible. LÄS MER

  4. 3. Small Intestinal Neuroendocrine Tumor Analyses : Somatostatin Analog Effects and MicroRNA Profiling

    Författare :Su-Chen Li; Valeria Giandomenico; Kjell Öberg; Marco Volante; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Small intestinal neuroendocrine tumors; Somatostatin analogs; Laser-capture microdissection; Microarray profiling and microRNA profiling; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : Small intestinal neuroendocrine tumors (SI-NETs) originate from serotonin-producing enterochromaffin (EC) cells in the intestinal mucosa. Somatostatin analogs (SSAs) are mainly used to control hormonal secretion and tumor growth. However, the molecular mechanisms leading to the control of SI-NETs are unknown. LÄS MER

  5. 4. Expression and localisation of somatostatin receptor subtype 2a in neuroendocrine cells and cells of neuroectodermal origin

    Författare :Sayed Hossein Hashemi; Göteborgs universitet; []

  7. 5. Design, Synthesis, and Evaluation of Functionalized Chroman-4-one and Chromone Derivatives. Somatostatin receptor agonists and Sirt2 inhibitors

    Författare :Maria Fridén-Saxin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chroman-4-ones; Chromones; Inhibitors; Molecular Modeling; Peptidomimetic; Samarium; Sirtuin; Sirt2; Somatostatin; Structure-Activity Relationships; Tubulin; β-Turn;

    Sammanfattning : Peptides are involved in many physiological processes such as regulation of blood-pressure, food intake, pain transmission and blood-glucose levels. They consist of amino acids that are connected through amide bonds which make peptides hydrophilic and conformationally flexible. LÄS MER
