Anthracycline anti-tumor effect depends on several mechanisms such as apoptosis induction via inhibition of topoisomerase II (TOP2), intercalation into the deoxyribonucleic acid (DNA) leading to an inhibition of macromolecules synthesis, or production of reactive oxygen species (ROS) causing DNA damage or lipid peroxidation (14). The gene discussed is TOP2A; the disease is neoplasm.
