Figure 6. The effect of puerarin against IL-1β-induced activation and protein cleavage of caspase-3 in TR-iBRB2 cells. A: The activity of caspase-3 was determined as described in the Methods section. All data are expressed as mean ± standard deviation (SD) of three experiments, and each experiment included triplicate repeats. **p<0.01 versus control; ^##p<0.01 versus interleukin (IL)-1β alone. B: Caspase-3 cleavage was assessed with western blot analysis. All data are representative of three independent experiments.
