摘要
To seek novel miRNAs for the diagnosis of Chronic Obstructive Pulmonary Disease (COPD), this study analyzed the differential expression of miRNA from blood samples of COPD patients and healthy smokers ( n = 3) by human microarray analysis. Then, some miRNAs were chosen for qRTPCR validation. A total of 158 miRNAs revealed by microarray analysis have been differentially expressed between the two groups, 33 miRNAs identified to be up-regulated, whereas 125 miRNAs have been down-regulated in COPD. qRT-PCR showed the miR-548h-5p was decreased in the COPD patients compared with healthy smokers ( p = 0.04). The sensitivity and specificity of miR-548h-5p to the diagnosis of COPD were 84.6% and 81.8%, respectively. In conclusion, it is recommend that miR-548h-5p as an approach to the diagnosis of COPD.
