6. Genomic instability and genetic heterogeneity in neuroblastoma tumours
Abstract : 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%. READ MORE

7. Exposure, telomere length, and cancer risk
Abstract : Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes. Telomeres play a key role in chromosome stability and regulation of the cellular lifespan. Telomeres are shortened during cell division, and probably, by not yet well characterised factors in the environment. READ MORE

8. Identification of protein signatures of genomic stability/instability in epithelial cancers
Abstract : Aneuploidy is a consistent genetic alteration of the cancer genome. At early steps in the sequence of malignant transformation during human tumorigenesis, chromosomal aneuploidies can be the first detectable genetic aberrations found. READ MORE

9. Role of latent EBV genes in the induction of genomic instability in Burkitt’s lymphoma
Abstract : Epidemiological and molecular evidence link Epstein-Barr virus (EBV) infection to a variety of lymphoid and epithelial malignancies but the contribution of the virus to tumorigenesis is unclear. Genomic instability, defined by the establishment of a mutator phenotype and characterized by the occurrence of non-clonal chromosomal aberrations, excessive DNA damage and defects in DNA repair, is the hallmark of malignant transformation.

10. Epstein-Barr virus and genomic instability : a new look at the mechanisms of viral oncogenesis
Abstract : EBV is associated with a variety of lymphoid and epithelial malignancies but the mechanisms of oncogenesis are still not fully understood. The aim of the work described in this thesis was to assess whether induction of genomic instability, as defined by the accumulation of non-clonal genetic aberrations, could play a role in EBV oncogenesis and identify the viral protein(s) responsible for this phenotype.
