MiRNAs expression in peripheral blood monouclear cells from stable COPD and healthy adults

To explore which miRNAs were altered in COPD, we performed a microRNA microarray analysis of peripheral blood mononuclear cells from stable COPD patients (n=6) and healthy controls (n=6). Sex, age, BMI and history of cigarette smoke were matched between different groups. Blood samples were obtained from stable COPD patients(n=6) and healthy adults (n=6) from clinical trial (NCT02037828). The study was in compliance with the Declaration of Helsinki and was approved by Peking University Institutional Review Board Office. Tianyu, Zhou
