PS dose-dependently increases AKT phosphorylation and reduces ERK phosphorylation of suspended LLC cells. a IBs were probed for various signaling proteins, and their phosphorylation statuses as indicated in the lysates of suspended LLC cells were treated without or with various concentrations of PS for 4 h at 37 °C. Quantifications of ERK (b), pERK (c), AKT (d), and pAKT (e) were normalized by GAPDH levels in (a)
