From: BRD4 is involved in viral exacerbation of chronic obstructive pulmonary disease
BRD4 expression is increased in COPD patients with viral exacerbation compared with those in stable condition. The relative mRNA levels (fold change) of BRD4 in the blood (A) and sputum (B) of stable COPD patients (sCOPD, n = 25) and COPD patients with viral exacerbation (AECOPD, n = 29) are shown. The correlation between the BRD4 expression levels in blood (C) and sputum (D) and forced expiratory volume in one second (FEV1) % predicted in stable COPD patients (n = 25) is shown. *P < 0.05, **P < 0.01
