Research

The main research area of the Department is the study of the mechanisms involved in the induction of chromosomal aberrations. Our group has analysed the action of different clastogenic agents (radiation, DNase I, AluI, BamHI, anti-Topo II compounds) in the induction and localisation of induced genetic damage. The relationship between chromosome breakpoint clusters and hyperacetylated chromatin was initially described by us.
