A: Gelatin zymogram showing activity of MMP-9 (88 kd active) and MMP-2 (70 kd latent and 62 kd active) in carotid arteries from control and doxycycline-treated rats 4 days after balloon catheter injury. B: Scanning densitometry was performed on zymogram gels, and the values for each MMP band were expressed as a percentage of the value obtained for control. Individual carotid extracts were prepared and run separately on the gel. Three samples per group were averaged to obtain these measurements.
