Figure 6. Effects of lenti-viral delivery to the hippocampus of the gene encoding ERα (Lenti-ERα) or a control virus (Lenti-Cherry) to aging ovariectomized rats on protein expression of choline acetyltransferase (ChAT) in the hippocampus as measured by western blotting.

Mean density x area (+SEM) expressed relative to Lenti-Cherry control. Representative blot images for ChAT and the loading control β-actin are shown in insets above the graph.
