Identification of long non-coding RNAs (lncRNA) antisense HOXA terminal transcriptional RNA (HOTTIP) with significant upregulation in asthma. A: Study flow chart of the present study screening lncRNAs in asthma. B: Volcano plots were performed to visualize differently expressed genes between asthma patients and healthy individuals. C: Volcano plots were performed to visualize differently expressed lncRNAs between asthma patients and healthy individuals. D: Heat map and hierarchical clustering demonstrated expression values of differently expressed lncRNAs.
