  1. 11. Molecular mechanisms of tumor development in hyperparathyroidism

    Författare :Filip Farnebo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :parathyroid; hyperparathyroidism; MEN 1; FIHP; loss of heterozygosity; comparative genomic hybridization; mutation analysis; in situ hybridization;

    Sammanfattning : Loss of heterozygosity (LOH) analysis and comparative genomic hybridization (CGH) were used in an attempt to identify recurrent chromosomal alterations in different types of parathyroid tumors. These included familial and sporadic, benign and malignant, as well as primary, irradiation associated and secondary tumors. LÄS MER

  2. 12. Classical cadherins and the thyroid. Studies on organ development and epithelial differentiation

    Författare :Mats Grände; Göteborgs universitet; []
    Nyckelord :Thyroid; cadherin; TGF-; EGF; MEK; development; EMT;

    Sammanfattning : The cadherins are key regulators of tissue patterning and organ formation. E-cadherin is important for cell-cell adhesion and promotes epithelial morphogenesis and maintenance of the epithelial phenotype. LÄS MER

  3. 13. Cellular Origin and Development of Glioma

    Författare :Nanna Lindberg; Lene Uhrbom; Bengt Westermark; Kristian Pietras; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; brain tumor; PDGF; RCAS TV-A; cell of origin; glial cell; oligodendrocyte progenitor cell; DNA repair; homology-directed repair; RAD51; angiogenesis; histidine-rich glycoprotein; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : Gliomas are the most common primary tumors of the central nervous system believed to arise from glial cells. Invasive growth and inherent propensity for malignant progression make gliomas incurable despite extensive treatment. LÄS MER

  4. 14. The Neuroblastoma Genome and Epigenome - Patient Stratification and Identification of Candidate Genes

    Författare :Helena Carén; Göteborgs universitet; []
    Nyckelord :cancer; neuroblastoma; epigenetics; DNA methylation; microarray; tumor suppressor gene; tumor; embryonal; neural crest; bisulfite sequencing; 1p36; 11q; MYCN; CASZ1; PIK3CD; PRKCDBP; SCNN1A; TGFBI; DHRS3; KRT19; DUSP23; APITD1; H2AFX;

    Sammanfattning : Neuroblastoma (NB) is a tumor of the sympathetic nervous system, and the most common extracranial tumor of childhood. The prognosis for high-stage NBs is still poor, with survival rates of about 35%. Side-effects of treatment in these young children can also be severe. LÄS MER

  5. 15. Characterization of the perturbed differentiation in neuroblastoma, aided by the analysis of normal sympathetic nervous system development

    Författare :Carolina Gestblom; Lund Wallenberg Neurocentrum; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; development; TrkA; apoptosis; proliferation; sympathetic nervous system; neuronal; paraganglia; neuroblastoma; chromaffin; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Neuroblastoma is a pediatric tumor derived from cells in the sympathetic nervous system. In an attempt to explain the heterogeneous clinical behavior of neuroblastoma tumors, neuroblastomas have been characterized with regard to their degree of sympathetic differentiation. LÄS MER
