BECN1 and ischemia: As shown in Figure 2A–B, 6 h after ischemia, although the ratio of LC3-II/LC3-I and the protein level of Beclin 1 increased significantly in rats subjected to ischemia with and without postconditioning than that in the sham-operated rats (Figure 2A–B; *p<0.05 vs. the Sham group), there was no significant difference between the two groups.
