  1. 6. Studies of epigenetic deregulation in parathyroid tumors and small intestinal neuroendocrine tumors

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

    Abstract : 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).

    Abstract : Neuroendocrine tumors (NETs), originally described as carcinoids, represent a rare and heterogeneous group of neoplasms associated with intensive secretion of hormones, bioactive peptides and amines. Most of the patients are diagnosed at a late stage of disease, often with liver metastases. READ MORE

  3. 8. Genes and brain tumors

    Author : Maral Adel Fahmideh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Although brain tumors are rare and combined with other nervous system tumors account for ~ 2% of all cancers, they are the second most common type of pediatric cancer. The etiology of brain tumors, known as multifactorial traits, is poorly understood. READ MORE

  4. 9. Small Intestinal Neuroendocrine Tumors : Clinical Studies, Novel Serum Biomarkers and Sensitivity to Cytotoxic and Targeted Agents

    Author : Kosmas Daskalakis; Peter Stålberg; Per Hellman; Olov Norlén; Robert Bränström; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; SI-NET; fibrosis; locoregional surgery; liver transplantation; biomarkers; ex vivo sensitivity.;

    Abstract : Small Intestinal Neuroendocrine Tumors (SI-NETs) are indolent neoplasms with an increasing annual incidence of approximately 1/100 000 people. They are often diagnosed at a late stage, restricting treatment efficacy. READ MORE

  5. 10. Genetic studies of endocrine abdominal tumors

    Author : Ola Hessman; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; MEN1; LOH; pancreatic endocrine tumors; midgut carcinoid; Smad4 DPC4; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Abstract : Pancreatic endocrine tumors (PETs) occur sporadically or in the familial multiple endocrine neoplasia type 1 (MEN1) syndrome, whereas midgut carcinoids are nonfamilial, malignant endocrine tumors of the intestine. For these tumor entities morphological criteria are of limited use for prognostic prediction and selection of treatment. READ MORE
