SIRT1 Activity in Peripheral Blood Mononuclear Cells Correlates with Altered Lung Function in Patients with Chronic Obstructive Pulmonary Disease

Figure 1

SIRT1 protein expression (a) and activity (b) in peripheral blood mononuclear cells (PBMCs). Data are expressed as mean ± SD. Sirtuin 1 (SIRT1) expression and activity were determined in the nuclei extracted from PBMCs of healthy nonsmokers (HnS), healthy smokers (HS), and COPD patients (COPD), respectively indicated with black circle, black square, and black triangle.
