6. Cell cycle regulation and DNA damage response : a record of polo-like kinase 1 activity
Sammanfattning : Division and cell proliferation is an essence of life. A human cell has in its core a very simple yet a very complex machinery to coordinate cell cycle activities and events. LÄS MER
7. Characterization of chromatin mobility upon DNA damage in Arabidopsis thaliana
Sammanfattning : Plant cells are subject to high levels of DNA damage from dependence on sunlight for energy and the associated exposure to biotic and abiotic stresses. Double-strand breaks (DSBs) are a particularly deleterious type of DNA damage, potentially leading to chromosome rearrangements or loss of entire chromosome arms. LÄS MER
8. Intoxication of mammalian cells by the cytolethal distending toxin of Haemophilus ducreyi : a novel mechanism of action
Sammanfattning : The cytolethal distending toxins (CDTs) are a newly described family of bacterial protein toxins with a novel mechanism of action: DNA damage. Haemophilus ducreyi produces a cytotoxin that belongs to this family. This bacterium causes chancroid, a sexually transmitted disease, characterised by mucocutaneous, slowly healing genital ulcers.

9. The use of IGF-IR inhibitors in cancer therapy : a potential approach for sensitizing tumor cells to ionizing radiation
Sammanfattning : This study focused on insulin-like growth factor I receptor (IGF-IR), considered as a promising therapeutic target for cancer treatment. We were in particular interested in the involvement of IGF-IR in tumor cells response to radiation and we tried to provide the rationale for a combined therapy of IFG4R inhibitors with radiation in order to improve the therapeutic outcome.

10. Expression and regulation of Rad51 in human cells
Sammanfattning : Double strand breaks (DSBs) can be caused by exogenous DNA damaging agents or by endogenous processes, and may lead to chromosomal breakage and rearrangement resulting in apoptosis or tumorigenesis. The repair of DSBs in higher eukaryotes is to a large extent accomplished by homologous recombination (HR), a process in which DNA from a complementary strand is used as a template for repair synthesis.
