Topoisomerase II alpha

SKU: 3045 Categories: , ,

Topoisomerase II alpha (Topo IIa) plays an important role in DNA synthesis and RNA transcription, as well as chromosomal segregation during mitosis. It is reported to be a sensitive and specific marker of late S-, G2- & M-phases in transformed and developmentally regulated normal cells. Topo IIa is also implicated in drug resistance of tumor cells and has been shown to be over-expressed in many human cancers. Decreased expression of Topo IIa is the predominant mechanism of resistance to several chemotherapeutic agents.
