16. Molecular Genetic Characterization of Acute Lymphoblastic Leukemia with a Poor Prognosis
Abstract : Acute lymphoblastic leukemia (ALL) affects individuals at all ages, with peak incidences in children 50 years. ALL is broadly categorized into B-cell precursor (BCP) and T-cell ALL with specific clinical features associated with outcome. READ MORE

17. p53 guardian of the genome and target for improved treatment of leukemia
Abstract : P53 acts in several cellular processes as cell cycle checkpoints, DNA repair senescence and the surveillance of genomic integrity. Wt p53 inhibits cancer processes by causing cell cycle arrest and apoptosis. P53 is strongly regulated by the HDM-2 protein, which builds a complex with p53 leading to proteosomal degradation of p53.

18. Molecular studies of prognostic and etiological factors in childhood leukemia
Abstract : Acute lymphoblastic leukemia (ALL) is the most common cancer in childhood. It is caused by the somatic acquisition of genetic abnormalities and malignant transformation of immature lymphocytes in the bone marrow, most commonly of B-cell lineage. READ MORE

19. Genomic instability and tumor progression : a cytochemical, molecular biological and cytogenetic study of human tissue from uterine cervix, colon, breast and ovary
Abstract : Disruption of cell cycle checkpoint control is believed to be common in human carcinomas. To elucidate how cell cycle defects and genomic instability cooperate we investigated the pathogenesis of carcinomas by using four different models of tumor progression in human tissue samples i.e. from the uterine cervix, colon, breast and ovary.

20. 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.
