DHQ inhibits MLE-12 cell viability. A, MLE-12 cells were treated with either 150 μm DHQ (○) or an equal volume of DMSO (•) for 24 and 48 h. The addition of DHQ to the culture medium significantly inhibited MLE-12 cell viability. p < 0.05 at 24 h; p < 0.005 at 48 h. B, DHQ inhibited the viability of MLE-12 cells in a concentration-dependent manner. The MLE-12 cells were treated in the presence of different concentrations DHQ for 48 h. The error bars are means ± S.E. from three independent measurements.
