The research is focused on factors involved in the generation of mutations in mammalian cells. This concerns both basic research and applied science. Basically, lesions induced by DNA damaging agents are mostly removed by DNA repair processes, but when DNA replicate, mutations occasionally occur. The processes involved during replication are rather complicated and is very much dependent on the type of lesions that block replication. DNA damage is also something that occurs due to lifestyle. We have currently research projects that evaluate biomarkers analyzed from volunteers having different diets. One of these projects is in collaboration with research groups in Europe, sponsored by EU.
