  1. 1. Array-based Genomic and Epigenomic Studies in Healthy Individuals and Endocrine Tumours

    Author : Johanna Sandgren; Gunnar Westin; Teresita Diaz de Ståhl; Göran Åkerström; Ola Hessman; Winand Dinjens; Uppsala universitet; []
    Keywords : genome; copy number variants; cancer; Pheochromocytoma; epigenome; array-CGH; ChIP-chip; gene expression; tumour suppressor genes; oncogenes; MEDICINE; MEDICIN; Surgery; Kirurgi;

    Abstract : The human genome is a dynamic structure, recently recognized to present with significant large-scale structural variation. DNA-copy number changes represent one common type of such variation and is found both between individuals and within the somatic cells of the same individual, especially in disease states like cancer.

  2. 2. Genetic Alterations in Pheochromocytoma and Paraganglioma

    Author : Jenny Welander; Peter Söderkvist; Oliver Gimm; Mercedes Robledo; Linköpings universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Pheochromocytoma; paraganglioma; genetics; sequencing; cancer; mutation;

    Abstract : Pheochromocytomas and paragangliomas are neuroendocrine tumors that arise from neural crest-derived cells of the adrenal medulla and the extra-adrenal paraganglia. They cause hypertension due to an abnormally high production of catecholamines (mainly adrenaline and noradrenaline), with symptoms including recurrent episodes of headache, palpitations and sweating, and an increased risk of cardiovascular disease.

  3. 3. Molecular studies of endocrine tumors : Insights from genetics and epigenetics

    Author : Samuel Backman; Per Hellman; Peter Stålberg; Olov Norlén; Robert Bränström; Uppsala universitet; []

    Abstract : Endocrine tumors may be benign or malignant and may occur in any of the hormone producing tissues. They share several biological characteristics, including a low mutation-burden, and may co-occur in several hereditary tumor syndromes. The aim of this thesis was to identify genetic and epigenetic aberrations in endocrine tumors. READ MORE

  4. 4. Genetic Aspects of Endocrine Tumorigenesis : A Hunt for the Endocrine Neoplasia Gene

    Abstract : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. READ MORE

  5. 5. Incidentally discovered adrenal tumours, adrenal metastases and pheochromocytomas - Clinical and epidemiological aspects

    Author : Andreas Muth; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Incidental Findings; Adrenal incidentaloma; Adrenal Gland Neoplasms; Adrenalectomy; Follow-Up Studies; Quality of Life; Pheochromocytoma epidemiology; Pheochromocytoma genetics; Paraganglioma epidemiology; Paraganglioma genetics;

    Abstract : With increasing use of high resolution radiological imaging incidentally discovered adrenal tumours (adrenal incidentalomas, AI) have become a common clinical problem. The aim of work-up and follow-up of patients with AI is to detect malignant (primary or metastatic) and/or hormone-producing tumours. READ MORE
