A number of studies have compared the expression of different lncRNAs in blood cells between asthma patients and healthy controls and identified several differentially expressed lncRNAs (Tsitsiou et al., 2012; Booton & Lindsay, 2014; Feng, Yang & Yan, 2020; Chen & Deng, 2022), among which maternally expressed gene 3 (MEG3) is of particular interest. Here, MEG3 is linked to asthma.
