Western blotting analysis of PI3-kinase in mouse hippocampal tissue on day 1 after treatment.

<p>The experimental animal groups are as described in the <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0026394#s4" target="_blank">methods</a> (n = 4/group). The top panel shows a representative immunoblot for PI3-kinase that was reprobed for α-tubulin as a loading control. The histogram in the bottom panel shows the densitometric measurements of the PI3-kinase signals on the immunoblot, relative to control. Values are the mean ± SEM.
