From: CircRNA0001859, a new diagnostic and prognostic biomarkers for COPD and AECOPD
CircRNA0001859 was downregulated in human bronchial epithelial cell subjected to CS/NNK or CS + NNK treatment. FISH assay was performed to evaluate the expression of circRNA0001859 in the human bronchial epithelial cell subjected to three different treatments (× 200, n = 6). b qRT-PCR was used to evaluate the expression of circRNA0001859 in the lung tissue (n = 6). *p < 0.05. Three independent biological repeats were carried out for each analysis
