1. 1. Pancreatic Endocrine Tumourigenesis : Genes of potential importance

   Författare :Térèse A. Johansson; Barbro Eriksson; Britt Skogseid; Gunnar Westin; Martin Bäckdahl; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pancreatic endocrine tumour; Multiple endocrine neoplasia type 1; Tumourigenesis; Notch signalling; Notch1; Hes1; Neurog3; Neurod1; Men1; Ascl1; Pou3f4; Pdx1; Rpl10; Dlk1; Dkk1; Tph1; menin; Tumour biology; Tumörbiologi;

   Sammanfattning : Understanding signalling pathways that control pancreatic endocrine tumour (PET) development and proliferation may reveal novel targets for therapeutic intervention. The pathogenesis for sporadic and hereditary PETs, apart from mutations of the MEN1 and VHL tumour suppressor genes, is still elusive. LÄS MER

3. 2. 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

4. 3. Characterizing the pancreatic "isletome" : 3D optical imaging to study diabetes

   Författare :Max Hahn; Ulf Ahlgren; András Gorzsás; Leif Carlsson; Alvin C. Powers; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D imaging; fluorescence microscopy; 3D image analysis; technique development; diabetes; Islet of Langerhans; Insulin; β-cell mass; pancreas; anatomy; molecular medicine medical sciences ; molekylär medicin medicinska vetenskaper ; medicinsk biokemi; Medical Biochemistry;

   Sammanfattning : The pancreas is a specialised multipurpose organ, that can be separated into two major compartments: endocrine and exocrine. The exocrine part makes up the majority of the organ volume and functions to secrete digestive enzymes into the small intestine. LÄS MER

5. 4. Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours

   Författare :Christina Swärd; Göteborgs universitet; []
   Nyckelord :Carcinoid; Endocrine pancreatic tumour; Neuroendocrine; Octreotide; Somatostatin receptor; Peptide receptor; Radionuclide therapy; Absorbed dose; Chromogranin A; Liver transplantation;

   Sammanfattning : Aspects on Diagnosis and Treatment of Gastrointestinal Neuroendocrine Tumours Background. Gastroenteropancreatic neuroendocrine tumours (GEP-NETs) originate from endocrine cells of the intestinal mucosa and pancreas. LÄS MER

7. 5. Hypoxia-inducible factor-1 (HIF-1) in pancreatic cancer cell aggressiveness and therapeutic resistance and the potential role for pancreatic endocrine cells in islet transplantation

   Författare :Xiaohui Jia; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Tissue hypoxia results from an inadequate supply of oxygen (O2) that compromises biologic functions in various tissues, including both normal and malignant. It is known that a heterodimeric transcription factor hypoxia-inducible factor-1 (HIF-1) mainly mediates this critical adaptation. LÄS MER
