Propofol treatment decreased ERK1/2 activation in A549 cells.

<p>(A) The Western Blot Image of time course of Phosphorylated ERK1/2 Expression in A549 Treated with 100 µM propofol. (B) The Quantification of the Western Blot. These results are representative of three independent experiments with a total of 15 samples. By using One Way ANOVA testing, we found the differences from all one-hour propofol groups to be significantly lower compared with the 0-hour group with a P value <0.0001. ANOVA was used to do the analysis.
