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

    Författare :Anna Lindkvist; Ylva Paulsson-Karlsson; Göran Roos; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Oesophageal cancer is a malignant and aggressive disease with very poor survival. The aim of this thesis was to evaluate novel therapeutic targets in oesophageal cancer. In paper I, Hsp90 was expressed in all 81 oesophageal cancer tissues and also in nine oesophageal cancer cell lines. LÄS MER

    Sammanfattning : Genetic mutations can cause a wide range of diseases, e.g. cancer. Gene therapy has the potential to alleviate or even cure these diseases. LÄS MER

  5. 4. 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

  7. 5. Signalling pathways in renal cell carcinoma with a focus on telomerase regulation

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

    Sammanfattning : 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. LÄS MER
