1. Bacterial DNA repair and molecular search
Sammanfattning : Surveillance and repair of DNA damage is necessary in all kinds of life. Different types of DNA damage require different repair mechanisms, but these mechanisms are often similar in all domains of life. The most serious type of damage, double stranded DNA breaks, are for example repaired in conceptually similar ways in both bacteria and eukaryotes. LÄS MER
2. Interstrand Crosslinks - Induction and repair
Sammanfattning : DNA crosslinking agents exhibit a variety of DNA lesions, such as monoadducts, DNA-DNA interstrand or intrastrand crosslinks or DNA-protein crosslinks. Agents that produce interstrand crosslinks (ICLs) exist naturally and are widely used in chemotherapy. Therefore, it is important to understand how the lesions induced by these agents are repaired.

3. Induction and repair of clustered DNA damage sites after exposure to ionizing radiation
Sammanfattning : The mechanisms that maintain genomic stability safeguard cells from constant DNA damage produced by endogenous and external stressors. Therefore, this thesis aimed to specifically address questions regarding the requirement and involvement of DNA repair proteins in the repair of various types of radiation-induced DNA damage. LÄS MER
4. Radiation response in human cells : DNA damage formation, repair and signaling
Sammanfattning : Ionizing radiation induces a range of different DNA lesions. In terms of mutation frequency and mammalian cell survival, the most critical of these lesions is the DNA double-strand break (DSB). DSB left unrepaired or mis-repaired may result in chromosomal aberrations that can lead to permanent genetic changes or cell death. LÄS MER
5. Role of Non-Homologous End-Joining in Repair of Radiation-Induced DNA Double-Strand Breaks
Sammanfattning : Efficient and correct repair of DNA damage, especially DNA double-strand breaks (DSBs), is vital for the survival of individual cells and organisms. Defects in the DNA repair may lead to cell death or genomic instability and development of cancer. LÄS MER
