  2. 1. Mitotic aberrations in mammalian cells

    Author : Anna Renglin Lindh; Thomas Helleday; Micheline Kirsch-Volders; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; aneuploidy; mitotic aberrations; chemical effects; human cancer; DNA repair; Genetics; Genetik;

    Abstract : Almost all cancer cells are aneuploid showing the wrong chromosome number and often with structural aberrations. The degree of aneuploidy correlates with an increase of the severity of the disease and tumour cells with chromosomal instability are more prone to acquire resistance to chemotherapy than other cells.

  4. 2. Centrosome aberrations and tumor development

    Author : Kaoru Fujioka; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Centrosome; cervical carcinoma; adrenocortical tumor; tetraploidization; p53; griseofulvin; 13-cis-retinoic acid.;

    Abstract : The transformation of a normal cell to a tumor cell is a result of a failure somewhere in a complicated system of coordination, checkpoints and control mechanisms of inhibitors and activators working as triggers and transactivators of genes of importance for cell cycle progression. In the present thesis, the focus is on an important function that controls the segregation of the chromosomes during cell division to the next generation of two daughter cells. READ MORE

  5. 3. Experimental radioimmunotherapy and effector mechanisms

    Author : David Eriksson; Torgny Stigbrand; Eva Forsell-Aronsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; radioimmunotherapy; apoptosis; mitotic catastrophe; caspases; cell cycle disturbances; combination treatment.; Immunology; Immunologi;

    Abstract : Radioimmunotherapy is becoming important as a new therapeutic strategy for treatment of tumour diseases. Lately monoclonal antibodies tagged with radionuclides have demonstrated encouraging results in treatment of hematological malignancies. The progress in treatment of solid tumours using radioimmunotherapy, however, has been slow. READ MORE

  6. 4. Optimizing experimental radioimmunotherapy : investigating the different mechanisms behind radiation induced cell deaths

    Author : Theres Lindgren; David Eriksson; Torgny Stigbrand; Bo Stenerlöw; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitotic catastrophe; senescence; cell cycle checkpoint; apoptosis; radiation; gene expression; p53; immunologi; Immunology; radiofysik; radiation physics;

    Abstract : Background. Radiation therapy is an important treatment regimen for malignant disease. Radiation therapy uses ionizing radiation to induce DNA damage in tumor cells in order to kill them. READ MORE

  7. 5. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours

    Author : David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; nuclear atypia; kinetochore; anaphase bridge; p53; breakage-fusion-bridge cycle; TP53; HMGIC; MDM2; mitotic instability; genomic instability; FISH; osteosarcoma; liposarcoma; amplification; tumour; chromosome; cytogenetics; Clinical genetics; Klinisk genetik;

    Abstract : Acquired genetic abnormalities are found in all types of malignant tumours and may contribute to neoplastic processes by altering protein structure or dosage. Many bone and soft tissue tumours (BSTT) are characterised by complex patterns of chromosome changes, including extensive intratumour heterogeneity and amplification of DNA sequences. READ MORE
