HDAC2 is regulated in relation to cognitive aging, recent experience and hippocampal region.

<p>(A–C) Quantification of HDAC2 levels in regions CA1 (A), CA3 (B) and DG (C). Representative western blots are organized according to the corresponding quantitative results. Protein levels were normalized to β-actin and the group data are represented as a percentage of young baseline values. Error bars = S.E.M. Asterisks denote p<0.05 relative to respective baseline.</p>
