Exercise decreases the expression of MMP-9 and inflammatory factors in vascular tissues. (A–B) Immunofluorescence representative images and relative expression of MMP-9 (red) in the thoracic aorta and brachiocephalic artery, respectively (n = 6 per group). (C–D) Immunofluorescence representative images and relative expression of IL-6 (green) in the thoracic aorta and brachiocephalic artery, respectively (n = 6 per group). (E–F) Immunofluorescence representative images and relative expression of TNF-α (green) in the thoracic aorta and brachiocephalic artery, respectively (n = 6 per group). **P < 0.01, ***P < 0.001, ns indicating P > 0.05.
