ANKRD42 and asthma: Differentially expressed genes (DEGs) in severe asthma endobronchial brushings (GSE63142, SARP), bronchial epithelial cells (GSE43696, SARP), epithelial brushings (GSE76226, U-BIOPRED) and bronchial biopsies (GSE76225, U-BIOPRED) were compared and a strong, positive correlation was observed between the datasets (r values between 0.66 and 0.89; P values between 4e−09 to 2e−16; Fig. 8a).
