Fig. 1From: 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 cellsResults of DNA microarray analysis. In the ALI group, there were 692 genes whose expressions were enhanced more than 2-fold by IL-13 (10 ng/ml) stimulation. In the freshly isolated BEC group, there were 433 genes whose expressions were enhanced more than 2-fold in snBA samples. The 44 genes common to both groups were extracted from the Venn diagram and displayed together with a heatmapBack to article page
