CDH2 and asthma: The results of EMT markers in asthma especially the ratio of E and N-Cadherins suggests an active EMT process in these patients as indicated in many studies reported in relation to EMT in asthma based on simulated epithelial cells, in-vivo animal model data, and house duct mice induced lungs (38–40), although EMT in asthma remains a subject of debate as no human tissue evidence is available including the hallmark of RBM fragmentation.
