Fig. 2From: Dipeptidyl peptidase-4 is highly expressed in bronchial epithelial cells of untreated asthma and it increases cell proliferation along with fibronectin production in airway constitutive cells DPP4 mRNA expression in freshly isolated BECs from asthma patients by qPCR. DPP4 mRNA was significantly enhanced in distal BECs in snBA. * P < .05 compared with stBA. b. DPP4 mRNA expression in distal BECs significantly correlated with eNO (r= 0.54, p=0.0377)Back to article page
