Fig. 1 shows the ferritin levels in cerebral cortex, hippocampus, and corpus striatum of both control and ischemia sides. Compared with the control side, the level of L–ferritin increased significantly in the three regions on the ischemia side (p <0.01) (Fig.1D). Similarly, the H-ferritin protein level was also significantly elevated in the cerebral cortex and the hippocampus but decreased in the corpus striatum (Fig. 1H) (p <0.05). Here, FTH1 is linked to ischemia.
