RBFOX3 and ischemia: However, the number of NeuN-immunoreactive neurons in the SP of the CA1 region of the 200 mg/kg OXC pre- and post-treated ischemia groups was similar (88.2% and 86.1%, respectively, of the sham groups) to that in the sham groups, and the distribution pattern of NeuN-immunoreactive neurons was also similar to that in the sham groups (Figure 2D,d,F,f,G).
