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

2. Mitotic aberrations in mammalian cells
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.

3. Mechanisms and Consequences of Chromosomal Instability in Malignant tumours
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. Mitotic recombination in mammalian cells
Abstract : Recombination is usually defined as the exchange of genetic material between two strands or regions of nucleic acids. This process occurs in all known organisms and is highly conserved, especially among higher eukaryotes. Various types of recombination, involving homologous or non-homologous nucleic acid sequences, are known to exist. READ MORE
