Hypothesis

To study DNA topoisomerase IIα (Topo-IIα) and -β expression and regulation in human ovarian cancer.

Conclusion

The study suggests that Topo-IIα and Topo-IIβ protein levels are up-regulated in ovarian cancer, indicating that Topo-IIβ may be a target for chemotherapy.

Supporting Evidence

  • The study investigated 15 ovarian tumor samples for Topo-IIα and -β expression.
  • Correlations were found between Topo-IIα mRNA and protein levels.
  • Topo-IIβ protein levels correlated better with Topo-II activity than Topo-IIα.

Takeaway

The researchers looked at proteins in ovarian cancer and found that two specific proteins are more active in cancer, which could help in treating it.

Methodology

The study used Northern blotting, quantitative RT-PCR, Western blotting, and a decatenation assay to analyze mRNA and protein levels.
