Fig. 5 — Anti-angiogenic drug treatment significantly reduces matrix metalloproteinase-9 (MMP-9) expression in the nasal septum. Nasal septum sections harvested from mice at (A) 0 or (B) 3 months were subjected to immunohistochemical staining for MMP-9, which was detected using confocal microscopy. Images were taken at ×400 magnification. Blue, DAPI; red, MMP-9. (C) Areas that stained positive for MMP-9 are reported for each group of mice as percentages of positive-stained area/whole area. Group A, phosphate-buffered saline treated; group B, inhalation of ovalbumin (OVA) treated; group C, dimethyl sulfoxide/OVA treated; group D1, OVA/SU1498 treated; group D2, OVA/AG1296 treated; group D3, OVA/SU1498/AG1296 treated.
