Western Blot analysis of p-H3S28 levels (normalized to total histone H3) in left ventricular (LV; a) and left atrial (LA; b) heart tissue of dogs with pacing-induced heart failure (HF) and respective non-failing controls (NF). All samples were normalized to GAPDH. Presented signals from NF and HF tissues were cropped from one continuous Western blot which is displayed as Suppl. Figure 9 (indicated by boxes).
