Phosphorylation and expression level of proteins of the PI3K-AKT pathway in brain.

<p>Representative western blot showing immunoreactivity for phosphorylated and total forms of AKT, p70S6K and GSK3β (above), phosphorylation level (middle), and expression level (below) in control or HU14 groups, in sensorimotor cortex (A), striatum (B), cerebellum (C) and visual cortex (D). *and ** p<0.05 and p<0.01 respectively with respect to C group. Values are mean ± SEM.
