EGFR and asthma: Among the affected signalling processes, some were single pathways (e.g., Notch and EGFR pathways enhanced in asthma), whereas others were represented by multiple terminal branches of the same pathway (e.g. Glucocorticoid hormone pathway and its four terminal branches upregulated in asthma; Integrin linked kinase (ILK) pathway and its eleven terminal branches upregulated in asthma; Supplementary Table S5).
