After an appropriate bioinformatics analysis, the authors concluded that these ceRNAs differentially expressed between healthy and COPD subjects could be involved in the regulation of 18 gene hubs, including TGFβ signaling and Wnt/β-catenin signaling, immune cell infiltration, M2 macrophage differentiation, and NK cell activation [9,11]. The gene discussed is TGFB1; the disease is chronic obstructive pulmonary disease.
