From: NOX4 expression and distal arteriolar remodeling correlate with pulmonary hypertension in COPD
An elevated expression of NOX4, α-SMA and TGFβ1 proteins in human COPD lung tissues. a Representative images of immunoblots showed more abundant NOX4, α-SMA and TGFβ1 proteins in COPD lung specimens as compared with of normal lung controls as determined by an immunoblotting assay; (b) Semi-quantitative analysis of the relative expression of NOX4, α-SMA and TGFβ1 proteins in COPD lungs by densometric analysis of immunoblots; (c) Quantitative analysis of the relative expression of NOX4 and α-SMA transcripts in COPD lung by reverse-transcriptional PCR. Compared with normal control lungs, *: P < 0.05, ***: P < 0.01 (N = 19 for non-COPD; N = 15 for COPD)
