GATA3 and asthma: Treatment with FP ex vivo demonstrated a concentration-dependent decrease in the direct interaction between phospho-GATA-3 and importin-α in PBMCs from patients with asthma (Figure 6A and 6B), which was significantly inhibited at 10−12 M FP (p<0.001, ANOVA and Newman-Keuls test) and completely attenuated by 10−8 M FP (p<0.001, ANOVA and Newman-Keuls test).
