GMFB and ischemia: Our results showed that, in the ischemia group, GMFβ protein levels were significantly upregulated in the ischemic cortex (P < 0.05, versus sham group) and slightly increased in the ischemic striatum (P > 0.05, versus sham group) at Rep 1 d (Figures 4(a) and 4(c)), whereas they were almost kept unchanged at Rep 7 d (Figures 4(b) and 4(d)).
