Ratio of active to latent MMP-2 as determined by quantitative immunoblot analysis. The percent change in the ratio of the active (64 kDa) to latent (72 kDa) MMP-2-immunoreactive bands was elevated at 2 and 4 wk post-TAA induction. No change was observed at 8 wk post-TAA induction, and a decrease in the ratio was observed at 16 wk post-TAA induction (*P < 0.05 vs. reference control animals).
