Figure 5. SP-2509 DR-washout cells lose their enhanced sensitivity to HDAC inhibitors.

(A) Parental and SP-2509 DR-washout A673 cells were treated with the indicated agents for 72 hrs. Cell viability was assessed through CellTiter Glo analysis. Data represents mean viability ± SEM from three independent experiments. (B) Mean IC₅₀ ± SEM and 95% confidence interval for each agent.
