Western blot analysis of MMP2, AQP4, and AQP9 protein expression in the lesion boundary zone of the ipsilateral hemisphere.

<p>(A) Western blot analysis of MMP2, AQP4, and APQ9. (B–D) Relative intensity of MMP2 (B), APQ4 (C), and AQP9 (D) in each of the five rat groups. Relative intensity is defined as the intensity of the target protein normalized to that of β-actin. Quantitative data (n = 4) are given as the mean ± the SD. ^△P<0.05 vs. group S; ^☆P<0.05 vs. group M; *P<0.05 vs. group A; ^ΦP<0.05 vs. group EA; ^ΟP<0.05 vs. group ED.
