FIGURE 6.
Effect of SIRT1 overexpression on hypoxia-induced pulmonary hypertension (HPH) rats. SIRT-1 expression (A) in pulmonary artery tissues form HPH rats was increased significantly at 8 days after intratracheal administration of Ad.SIRT1 or Ad.GFP (1 week of hypoxia). SIRT-1 is expressed relative to β-actin. Overexpression of SIRT1 decreased mPAP (B) in HPH rats. Values are mean ± standard error of the mean (n = 6). *P < 0.05, **P < 0.01 versus HPH + Ad.GFP 1w or 2w using an unpaired Student 2-tailed t test.
