  2. 1. Activity and Regulation of Telomerase in Malignant Cells

    Author : Anna Lindkvist; Ylva Paulsson-Karlsson; Göran Roos; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; apoptosis; ATC; c-Myc; drug sensitivity; ESCC; hTERT; hypoxia; IFN; MM; neuroblastoma; p53; telomerase; TGF-β; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin;

    Abstract : An important step in tumorgenesis is the acquisition of cellular immortality. Tumor cells accomplish this by activating the enzyme telomerase, and thereby avoiding replicative senescence. The aim of this thesis was to study the activity and regulation of telomerase in a panel of malignant cell types. READ MORE

  4. 2. Signalling pathways in renal cell carcinoma with a focus on telomerase regulation

    Author : Raviprakash Tumkur Sitaram; Göran Roos; Anders Bjartell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Renal cell carcinoma; DJ-1; NBS1; PTEN; WT1; cMyc; hTERT; telomerase; Pathology; Patologi; patologi; Pathology;

    Abstract : Telomerase is a ribonucleoprotein complex that catalyses telomeric repeat addition at the ends of chromosomes. The catalytic subunit, hTERT, acts as a key determinant for telomerase activity control; the induction of hTERT expression is required for telomerase activity. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Development of adenoviral vectors for monitoring telomerase activity in living cells

    Author : Anna Edqvist; Neurokirurgi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytogenetics; Genetics; cancer; onkologi; Cytologi; cancerology; oncology; Cytology; GBM; HSC; adenovirus; hTERT; Genetik; cytogenetik;

    Abstract : ABSTRACT Telomerase activity is a potential molecular marker for cancer and primitive cells in regenerative tissues. The most commonly used method to measure telomerase activity in cells is the telomerase reverse amplification protocol (TRAP) assay, where the protein extracts derived from homogenized cells are analysed.

  7. 5. Integration of Molecular Biology and Morphology in Effusions with Focus on in situ Detection of Telomerase and its Components

    Author : Nooreldin Zendehrokh; Malmö Patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pathological anatomy; Patologi allmän ; patologisk anatomi; Diagnostics; Diagnostik; cancer; TRAP in situ; onkologi; Cytologi; cancerology; oncology; Cytology; Medicin människa och djur ; Medicine human and vertebrates ; General pathology; Telomerase;

    Abstract : Clinical cytology is a rapid method to detect malignancy in effusions of the serous cavities, but the morphological characteristics of the cells do not always allow diagnosis and a specific marker for malignant cells would improve the diagnostic performance. Telomerase adds telomere repeats to the chromosome ends. READ MORE
