The direct phosphorylation of thr(1342) of topoisomerase iialpha by plk3 was demonstrated with an in vitro kinase assay, and overexpression of plk3 induced the phosphorylation of thr(1342) in cellular topoisomerase iialpha. it is possible that plk3 regulates the activity of topoisomerase iia by phosphorylation in a cell-cycle dependent manner. Another possibility is that plk3 regulates the activity of topoisomerase iia when the checkpoint is activated. |

In contrast to other cytotoxic topoisomerase II inhibitors (acridines, epipodophyllotoxins), anthracyclines produce persistent DNA cleavable complexes. This property is more evident with doxorubicin derivatives than with daunorubicin derivatives. |

Topoisomerase II (Top2) is a nuclear enzyme involved in several metabolic processes of DNA. Chemotherapy agents that poison Top2 are known to induce persistent protein-mediated DNA double strand breaks (DSB). In this report, by using knock down experiments, we demonstrated that Top2α was largely responsible for the induction of γH2AX and cytotoxicity by the Top2 poisons idarubicin and etoposide in normal human cells. |

Recognition of transient DNA breaks induced by teniposide, etoposide, and other podophyllotoxin analogues established not only that their site of activity was DNA but also that their cytotoxic effect was dose-dependent. Extensive investigation has further indicated that a primary mechanism of action of these agents involves inhibition of the catalytic activity of eukaryote topoisomerase II and, more important, the consequent stabilization of the normally transient covalent intermediate formed between the DNA substrate and the enzyme. |

Valrubicin (N-trifluoroacetyladriamycin-14-valerate) is a semi-synthetic derivative of the anthracycline doxorubicin. Valrubicin inhibits the incorporation of nucleosides into nucleic acids, causing extensive chromosomal damage and cell-cycle arrest in the G2 phase. Its principal metabolites inhibit topoisomerase II, thus arresting DNA synthesis. |
