Figure 3 Effect of dioscin on IL-1β–activated apoptotic activity in human NP cells. (A, B) Apoptotic activity was evaluated using the TUNEL method. (C–F) Western blotting and quantitative analysis of cleaved caspase-3, -9, and Bcl-2 expressions. (G) Fluorescence immunostaining of cleaved caspase-3 (red) and nucleus (blue). The results are presented as the means ±SD. * P<0.05 relative to the control group; # P<0.05 relative to the IL-1β group, n=5.
