6. Decoding the Structural Layer of Transcriptional Regulation : Computational Analyses of Chromatin and Chromosomal Aberrations
Abstract : Gene activity is regulated at two separate layers. Through structural and chemical properties of DNA – the primary layer of encoding – local signatures may enable, or disable, the binding of proteins or complexes of them with regulatory potential to the DNA. READ MORE

7. Characterisation of chromosomal aberrations in childhood leukaemia
Abstract : Acute lymphoblastic leukaemia (ALL) is the most common malignancy in childhood, accounting for approximately 25% of all paediatric malignancies. Based on clinical risk criteria and modem laboratory investigations including immunophenotyping, cytogenetics, and molecular genetics, patients can be divided into prognostic groups and assigned to risk- adjusted treatment protocols.

8. 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

9. Case-control studies on risk factors for myeloid leukemias and myelodysplastic syndromes
Abstract : Case-control studies comprising telephone interviews for 333 cases of acute myeloid leukemia (AML), 226 cases of Philadelphia chromosome-positive chronic myeloid leukemia (Ph+ CML), 330 cases of myelodysplastic syndromes (MDS), and matched controls were conducted. Information had to be obtained from next-of-kin much more often for cases (85%) than for controls (18%). READ MORE

10. Molecular studies of pancreatic cancer: Characterization of the transforming growth factor beta signaling pathway
Abstract : In the present thesis, genetic abnormalities in pancreatic cancer were studied, with special emphasis on alterations of components involved in the transforming growth factor beta (TGFB) signaling pathway. In the first study, fluorescence in situ hybridization and cytogenetic analyses revealed aberrations of chromosome 18 in all 13 pancreatic carcinoma cell lines studied, in particular frequent breaks close to the centromere of chromosome arm 18q.
