Bronchial gene expression signature associated with rate of subsequent FEV1 decline in individuals with and at risk of COPD

Abstract excerpt

Background COPD is characterised by progressive lung function decline. Leveraging prior work demonstrating bronchial airway COPD-associated gene expression alterations, we sought to determine if there are alterations associated with differences in the rate of FEV1 decline. Methods We examined gene expression among ever smokers with and without COPD who at baseline had bronchial brushings profiled by Affymetrix...
