Figure 1. Formation of RH1-induced DNA cross-links in MDA468 and NQ16 cells.

Figure 1

Cells were treated with RH1 for 2 h. DNA cross-linking was measured by the modified comet assay and expressed as percentage decrease in tail moment compared with untreated controls. The percent of DNA in comet tail was also recorded and listed in Table S2. Results are expressed as the mean ± standard deviation of three separate determinations. * Significantly different from parental MDA468 cells treated with same RH1 concentration, p < 0.05, ** p < 0.01.
