In this study, we established lncRNA‐mRNA co‐expression network via weighted gene co‐expression network analysis (WGCNA, Figure 1A) and various lncRNAs that are highly correlated with TGF‐β1 expression (correlation coefficient > 0.8, Figure 1B and Table S1) based on the previous sequencing results of lung tissues samples from non‐COPD and COPD patients.17 Here, TGFB1 is linked to chronic obstructive pulmonary disease.
