Figure 7. — OTI28 induces lower levels of DNA cleavage mediated by an etoposide-resistant mutant yeast topoisomerase II (H1011Y) as compared to wild-type yeast topoisomerase II. Quantification of the relative levels of enzyme-mediated DNA cleavage at site 24–25 (indicated as the band labeled 24 in the inset) mediated by wild-type (yTop2WT) and H1011Y mutant (yTop2H1011Y) yeast topoisomerase II on an unmodified PML top strand hybridized to OTI28 (graph: +enz, red; inset: +WT, +H1011Y). DNA cleavage is normalized to background levels of DNA when no enzyme is present (graph: -enz, blue; inset: -WT, -H1011Y). Error bars represent the standard deviation of three independent experiments. Significance was determined by a paired t-test. P-values are indicated by asterisks (***P < 0.0005).
