From: Lipoteichoic acid induces surfactant protein-A biosynthesis in human alveolar type II epithelial cells through activating the MEK1/2-ERK1/2-NF-κB pathway

Figure 5

Effects of lipoteichoic acid (LTA) on the phosphorylation of extracellular signal-regulated kinase (ERK) 1/2. A549 cells were exposed to 30 μg/ml LTA for 1, 6, and 24 h. Phosphorylated ERK1/2 (p-ERK1/2) were immunodetected (A, top panel). ERK2 was detected as the internal standard (bottom panel). These immunorelated protein bands were quantified and analyzed (B). Each value represents the mean ± SEM for n = 6. An asterisk (*) indicates that a value significantly differed from the control group, p < 0.05. AU, arbitrary unit.
