Figure 5 QXT attenuated ERK activation in OVA-challenged mice and human lung epithelial cells. (A, B) ERK1/2 phosphorylation levels were examined by Western blot (n=8). (C, D) 16HBE cells were treated with H2O2 (40 μM) plus the water or ethanol extract from QXT (80 μg/mL) for 48 h. The protein levels of phospho-ERK and ERK were detected by Western blotting (n=3). (B, D) Phospho-ERK protein concentrations were quantified by using Image J software and normalized to β-actin. Data are shown as the mean±standard, * P<0.05, ** P<0.01.
