The expression of S100A8 increased 24 h after stroke induction in the ipsilateral hemisphere vs. the contralateral hemisphere (p < 0.01) and versus all the other days of the experiment (Figure 2D; p < 0.01 for 6 h and 7 d and p < 0.001 for 3 d). The gene discussed is S100A8; the disease is stroke disorder.
