Figure 4. The effect of puerarin against IL-1β-induced alternation of Bcl-2 family expression in TR-iBRB2 cells. A: The expression levels of Bax and Bcl-2 were detected using an immunoblotting assay. B: Densitometry analysis of Bax and Bcl-2 protein expression. All data are expressed as mean ± standard deviation (SD) of three experiments, and each experiment included triplicate repeats. ^a/^b/^c: p<0.05, p<0.01 versus control; */^#/^Δ: p<0.05, p<0.01 versus IL-1β alone.
