Figure 3. Baicalein inhibits OVA-induced IL-4, IL-5, and IL-13 expression at the mRNA level. The mRNA levels of IL-4 (A), IL-5 (B), and IL-13 (C) were determined by using RT-qPCR and were normalized to those of β-actin. (Results are presented as the mean ± SEM; n = 6 mice per group. ##P < 0.01 vs the control group; *P < 0.05, **P < 0.01 vs the OVA/Vehicle group).
