1. Regulation of DNA damage responses by the Myc oncogene : implications for future anti-cancer therapies
Abstract : Myc is a transcription factor frequently found deregulated in human cancer. Cells with deregulated expression of Myc carry a selective advantage against its neighbours due to the fact that Myc-mediated transcription governs crucial cellular events such as proliferation and growth.

2. DNA Damage Response of Normal Epidermis in the Clinical Setting of Fractionated Radiotherapy : Evidence of a preserved low-dose hypersensitivity response
Abstract : Investigations of DNA damage response (DDR) mechanisms in normal tissues have implications for both cancer prevention and treatments. The accumulating knowledge about protein function and molecular markers makes it possible to directly trace and interpret cellular DDR in a tissue context. READ MORE

3. Quantification of Radiation Induced DNA Damage Response in Normal Skin Exposed in Clinical Settings
Abstract : The structure, function and accessibility of epidermal skin provide aunique opportunity to study the DNA damage response (DDR) of a normaltissue. The in vivo response can be examined in detail, at a molecularlevel, and further associated to the structural changes, observed at atissue level. READ MORE

4. Induction of apoptosis in relation to chromatin structure and inhibition of replication by DNA damage from ionizing radiation
Abstract : The theme of this thesis has been chromatin organization ranging from methodological studies to involvement in apoptotic response. The aims have been: (i) to compare the information obtained by the AVTD method and comet assay concerning DNA-loop organization, (ii) to test the hypothesis that DNA-loop relaxation could be the triggering signal for induction of apoptosis in G0-lymphocytes, and (iii) to study the dose response for inhibition of the replication fork movement and pathways for the DNA repair process at the replication fork.

5. Replication Fork Stability in Mammalian Cells
Abstract : Maintaining replication fork integrity is vital to preserve genomic stability and avoid cancer. Physical DNA damage and altered nucleotide or protein pools represent replication obstacles, generating replicative stress. Numerous cellular responses have evolved to ensure faithful DNA replication despite such challenges. READ MORE
