Effects of PLE on the expressions and phosphorylation of Syk and its downstream signaling molecules in vivo. (a) The representative photomicrographs (×200), (b) percentage of positively stained cells, and (c) mean integrated optical density (MOD) of Syk staining (n = 15 independent slices from three mice in each group). (d) Representative photomicrographs (×200), (e) percentage of positively stained cells, and (f) MOD of p-Syk staining (n = 15 independent slices from three mice in each group). The expression of (g) Syk, (h) p-Syk, (i) PKC, (j) p-PKC, (k) p65, (l) p-p65, (m) cPLA2, and (n) p-cPLA2 in OVA-induced asthma mouse lung tissues was determined by WB (n = 5). ##P < 0.01vs. the control group; ∗P < 0.05 and ∗∗P < 0.01vs. the model group.
