  1. 1. The immortalization process of T cells : with focus on the regulation of telomere length and telomerase activity

    Författare :Sofie Degerman; Göran Roos; John Sedivy; Umeå universitet; []
    Nyckelord :immortalization; senescence; T cells; Nijmegen breakage syndrome; telomere; telomerase; hTERT; generic aberrations; methylation; MEDICINE; MEDICIN; Pathology; patologi;

    Sammanfattning : Cellular immortalization is a major hallmark of cancer and is a multi-step process that requires numerous cell-type specific changes, including inactivation of control mechanisms and stabilization of telomere length. The telomeres at the chromosome ends are essential for genomic stability, and limit the growth potential of most cells. LÄS MER

  3. 2. Disease-causing Keratin Mutations and Cytoskeletal Dysfunction in Human Skin : In vitro Models and new Pharmacologic Strategies for Treating Epidermolytic Genodermatoses

    Sammanfattning : Epidermolysis bullosa simplex (EBS) and epidermolytic ichthyosis (EI) are rare skin fragility diseases characterized by intra-epidermal blistering due to autosomal dominant-negative mutations in basal (KRT5 or KRT14) and suprabasal (KRT1 or KRT10) keratin genes,  respectively. Despite vast knowledge in the disease pathogenesis, the pathomechanisms are not fully understood, and no effective remedies exist. LÄS MER

  4. 3. p16INK4A and p15INK4B in senescence, immortalization and cancer : gene transfer by adenovirus vectors

    Författare :Jonas Fuxe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The astrocytic gliomas are the most common form of brain tumors in humans. The malignant progression from low grade (astrocytoma, grade II) to high-grade (glioblastoma multiforme, grade, IV) astrocytomas is well documented and is accompanied by an increasing number of genetic aberrations.

  5. 4. Post-translational modifications of proteins in human breast cancer : proteomics studies of phosphorylation and nitration and implication of these PTMs in tumorigenesis

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

    Sammanfattning : Breast cancer is the most common cancer in women. Even though improvements in diagnosis and treatment of breast cancer have been made, it is still the most common cause of cancer death in women. There is a great need to find biomarkers for early detection of the disease and novel drug targets to fight the cancer. LÄS MER

  7. 5. Expression of Ig genes. Regulation of transcription and production of human antibodies

    Författare :Christina Furebring; Institutionen för immunteknologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Bioteknik; Biotechnology; human antibodies; immunoglobulin gene expression; 3 enhancer; serology; transplantation; Immunologi; serologi;

    Sammanfattning : During B lymphocyte development, the transcriptional activity of the IgH locus is subject to spatial and temporal changes. The 3' enhancer (3'E) has been suggested to play an important role in regulation of immunoglobulin gene expression late in B cell development. LÄS MER
