MiR-221-3p and miR-92a-3p enhances smoking-induced inflammation in COPD.

Abstract excerpt

BACKGROUND: Smoking is likely to facilitate airway inflammation and finally contributes to chronic obstructive pulmonary disease (COPD). This investigation was intended to elucidate miRNAs that were involved in smoking-induced COPD. METHODS: Altogether 155 COPD patients and 77 healthy volunteers were recruited, and their serum levels of miR-221-3p and miR-92a-3p were determined. Besides, human bronchial...
