NCIt definition : A complex between the enzyme DNA topoisomerase 1 (TOP1) and its DNA substrate. Under
normal conditions these complexes are transient and found at low levels. In the presence
of therapeutic TOP1 inhibitors these complexes are stabilized, which prevents DNA
religation and induces lethal DNA strand breaks.;
