DNA topoisomerase II mutations and resistance to anti-tumor drugs.

Abstract excerpt

Mutations in DNA topoisomerase II are often correlated with drug-resistance in tumor cell lines. Studies of topoisomerase II-mediated drug-resistance in various model systems, as well as the sequencing of such mutations from drug-resistant tumors, have shed light on the functional domains of topoisomerase II, on how it interacts with inhibitors, and on the different mechanisms by which cells avoid the toxic...
