CASP3 and asthma: We observed that Caspase-3 protein expression detected by IF was significantly reduced in the asthma group vs. the control group (Figures 5(a) and 5(b); all P < 0.01) and was increased after drug administration of each group (all P < 0.01); Caspase-3 mRNA expression by qPCR was significantly decreased in asthma group vs. control group (Figure 5(c); P < 0.01) and was upregulated after the treatment of EEL and Bud&EEL (P < 0.05 or 0.01).
