Fig. 6. Hyperacetylation of histone H3 following HDAC inhibitor treatment and heat
shock induction. (A,B) Western blots of the acetylated histone H3 (AcH3) in
long-lived and in short-lived flies, respectively. The results of
photodensitometric analysis of A and B are shown in C. The upper bands are the
internal reference actin, and the lower bands are acetylated histone H3.
Values shown are the mean ± S.D. of three
independent experiments. *Significant (P<0.05);
**highly significant (P<0.01). Abbreviations as in
