Figure 2: Decreases in OSA D17 cell viability were observed with the addition of DOX-M. Significant differences were found when comparing the OSA control population to OSA cells incubated with 10 µM free DOX, 10 µM DOX-M, and the 1 µM DOX-M at 48 (p<0.05), 72 (p<0.001), and 96 hours (p<0.0001). Significant differences were also observed when comparing the control OSA population to OSA cells incubated with 0.1 µM DOX-M and 0.01 µM DOX-M at 72 (p=0.0003 and <0.0001 respectively) and 96 hours (p<0.0001 for both DOX-M concentrations).
