  2. 1. Mechanisms and Consequences of Chromosomal Instability in Malignant tumours

    Author : Ylva Stewénius; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; structural rearrangement; Ewing family tumour; Chromosomal instability; nephroblastoma; Wilms tumour; chromosomal aberration; anaphase bridge; subtelomeric FISH; breakage-fusion-bridge cycle;

    Abstract : In this thesis, telomere deficiency with subsequent anaphase bridging was found to be associated with chromosomal instability in established colorectal cancer cell lines and in Wilms tumour. In colorectal cancer cell lines, anaphase bridging was observed to generate both numerical and structural chromosomal aberrations and was also associated with the presence of multipolar mitoses.

  4. 2. 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

  6. 4. Rectal Cancer - Tumor Biology and Prognostic Markers

    Author : Eva Fernebro; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prognostic markers; Cytology; oncology; cancerology; Cytologi; onkologi; cancer; immunohistochemistry IHC ; chromosomal instability CIN ; microsatellite instability MSI ; tissue microarray TMA ; tissue inhibitor of metalloproteinase 1 TIMP-1 ; Rectal cancer; soluble urokinase plasminogen activator receptor suPAR ;

    Abstract : Colorectal cancer is one of our most common malignancies and the second leading cause of cancer death worldwide. About 1/3 of the tumors are located in the rectum. READ MORE

  7. 5. Chromosome dynamics and genomic instablity in neuroblastoma. Three genomic pillars: MYCN amplification, numerical and structural changes

    Author : Gisela Lundberg; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroblastoma; MYCN; telomeres; chromosomal instability;

    Abstract : In this thesis, the main focus has been on the childhood cancer neuroblastoma, one of the most common and lethal childhood tumours. Neuroblastoma has througout the years continued to be a clinical and biological enigma. READ MORE
