  1. 11. Molecular aspects of tumor development and treatment for small intestinal neuroendocrine tumors

    Författare :Omid Fotouhi; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Small intestinal neuroendocrine tumors (SI-NETs) may cause symptoms due to excess secretion of hormones and peptides. The molecular mechanisms behind development of SINETs are not well understood. Copy number alterations, especially loss of chromosome 18q, have been reported and recently p27 mutations were implicated in SI-NET tumorigenesis. LÄS MER

  3. 12. Studies of epigenetic deregulation in parathyroid tumors and small intestinal neuroendocrine tumors

    Författare :Elham Barazeghi; Gunnar Westin; Peter Stålberg; Per Hellman; Christofer Juhlin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epigenetics; 5hmC; TET1; TET2; parathyroid tumors; SI-NET; RRBS; PTPRM;

    Sammanfattning : Deregulation of the epigenome is associated with the initiation and progression of various types of human cancers. Here we investigated the level of 5-hydroxymethylcytosine (5hmC), expression and function of TET1 and TET2, and DNA methylation in parathyroid tumors and small intestinal neuroendocrine tumors (SI-NETs).

    Sammanfattning : Small intestine neuroendocrine tumors (SI-NETs) and lung carcinoids (LCs) are relatively indolent tumors, which originate from neuroendocrine (NE) cells of the diffuse NE system. Metastases can spread before diagnosis. Thus, potential cures become unavailable, which entitles new biomarker development. LÄS MER

  5. 14. In vitro studies on intestinal epithelial cell proliferation : effects of cytokines, Helicobacter pylori, serotonin and neuroendocrine peptides

    Författare :Kristina Zachrisson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Ammonia; Apoptosis; cell culture; cytokines; DNA synthesis; FHs-74 cells; Helicobacter pylori; IEC-6 cells; mitosis; neuroendocrine peptides; organ culture; serotonin;

    Sammanfattning : Previous studies suggest that bacteria and bacterial metabolites, proinflammatory cytokines, neuroendocrine peptides and amines may participate in the regulation of the gastrointestinal-epithelial cell kinetics. The complexity of interactions that take place in vivo makes it difficult to define the primary actions of these and other agents on gastrointestinal cell proliferation. LÄS MER

  7. 15. Therapy of neuroendocrine tumors with 177Lu-octreotate - Human tumor cell types and models and optimization of treatment : Terapi av neuroendokrina tumörer med 177Lu-octreotate

    Författare :Johanna Dalmo; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; somatostatin; radionuclide therapy; receptor up-regulation; RBP; nephrotoxicity;

    Sammanfattning : Neuroendocrine (NE) tumors (NET) have often metastasized at the time of diagnose, which makes it hard to cure patients with NET. Radiolabeled hormone analogues (especially somatostatin analogues, SS) can be used for diagnostics (e.g. 111In-octreotide) and therapy (e. LÄS MER
