Genome dynamics in cell programming, aging and human disease
DNA in our cells is continuously damaged through its exposure to reactive agents of endogenous or environmental origin. Damage to DNA, however, does not only occur randomly by chemical reactions, but also on purpose, by the action of enzymes, to increase genetic variance or alter cell fate determining epigenetic marks, i.e., DNA methylation. Modifications of either kind occur thousands of times in our DNA every day and need to be controlled if genome integrity is to be maintained. We investigate molecular mechanisms underlying this structural and functional dynamics of genomes.
