Assessing the change in the apoptotic processes activity in rat brain neurons under experimental cerebral ischemia, an increase in the concentration of caspase-3 and AIF (Figure 8) in NC groups of animals relative to SO rats by 8.9 (P<0.05) times and 10.4 (P<0.05) times, respectively was noted. The gene discussed is CASP3; the disease is Cerebral ischemia.
