Data are means ± SE; n ≥ 3. WT, wild type; SIRT1+/−, silent information regulator of transcription 1 (SIRT1) deficient; SIRT1+++, SIRT overexpressing. For Fig. 2, A and B, lysine acetylation densitometry was performed in the range of 25–100 kDa and normalized to protein across the same molecular mass range from Ponceau S-stained membranes. For Fig. 3, SIRT1 and MnSOD were normalized to actin; phospho-endothelial nitric oxide synthase (eNOS), Ac p65, and LC3 II were normalized to eNOS, p65, and LC3 I, respectively.
