MUC5AC and allergic asthma: Seventeen proteins (MUC5AC, ALOX5, CHI3L1, ORMDL3, RNASE3, POSTN, TGFB1, CCLA1, MUC5B, IL-4R, IL-17A, IL-33, SELL, IL-25, SERPINB2, IL-1R2, and BAX) were found to have a “high” relationship level with allergic asthma (Table 2B), and 16 proteins (MUC5AC, CHI3L1, POSTN, IL-33, RNASE3, SELL, ORMDL3, MUC5B, ALOX5, IL-17A, PTGER2, CCL5, IL-25, CCLA1, SERPINB2, CCL11) with non-allergic asthma (Table 2C).
