  1. 1. Chromosomal Instability and Genomic Amplification in Bone and Soft Tissue Tumours

    Författare :David Gisselsson Nord; Avdelningen för klinisk genetik; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Development and Application of Human Chromosome 22 Genomic Microarray : Chromosome 22-Associated Disorders Analyzed by Array-Based Comparative Genomic Hybridization

    Författare :Magdalena Benetkiewicz; Jan Dumanski; Niklas Dahl; Frank Speleman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular genetics; DNA copy number changes; chromosome 22; genomic microarray; array-CGH; schwannoma; neurofibromatosis type 2; ovarian carcinoma; breast cancer; Wilms tumor; Genetik; Genetics; Genetik;

    Sammanfattning : The array-based form of comparative genomic hybridization (array-CGH) is a new methodology that has shown to be of significant importance. This thesis focuses on the development of array-CGH with the aim to define candidate regions/genes on chromosome 22 in a wide spectrum of cancer-related conditions. LÄS MER

  4. 3. Genomic instability and genetic heterogeneity in neuroblastoma tumours

    Författare :Niloufar Javanmardi; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuroblastoma tumour; subclone; mutation; relapse; deep sequencing; tumour supressor gene;

    Sammanfattning : Neuroblastoma (NB), a tumour of the sympathetic nervous system and the most common malignant disease of early childhood, is responsible for 9% of paediatric cancer related deaths. Aggressive NB still constitutes a major clinical problem with survival rates of about 35%. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Tumour evolution and novel biomarkers in breast cancer

    Författare :Jana Biermann; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; breast cancer; gene signature; molecular biomarkers; tumour clonality; genomic instability; Swedish haemangioma cohort;

    Sammanfattning : Several gene signatures have been proposed in the past two decades to improve outcome prediction for breast cancer patients and to guide treatment decisions. Current treatment guidelines, however, primarily focus on established clinicopathological features. LÄS MER
