Figure 2.

Acetylation on histone 4 (H4) specific lysine residues 5 (K5) (A), 8 (K8) (B), 12 (K12) (C) and 16 (K16) (D) in a Sham (control) and trinitrobenzene sulfonic acid (TNBS) rat model of colitis. Results were obtained by Western blotting. In order to evaluate changes in density from different western blotting experiments control densitometry was denoted as 100% and differences were accounted as increase percentage of the control. Representative examples of bands obtained are also illustrated. Columns represent the densitometric evaluation of three independent experiments (mean ± SEM). (*p < 0.05 vs Sham proximal or Sham distal respectively).
