MEG3 and asthma: A recent review discusses that lncRNA maternally expressed gene 3 (MEG3), lncRNA OPA-interacting protein 5 antisense transcript 1 (OIP5-AS1), and ln-cRNA taurine upregulated gene 1 (TUG1) are involved in asthma and COPD pathogenesis by sponging different miRNAs.[5] Further research into the ncRNAs mentioned above as biomarkers for the diagnosis of COPD overlapping with asthma is warranted.
