The total number of PGC-1α-expressing neurons was also significantly higher in the Stroke + Mexidol and Stroke + Semax groups at Day 21 of the observations: 1.5-fold and 1.4-fold (p < 0.05) increases, respectively, compared to the Stroke + Saline group (Figure 7A,B, Figures S29 and S30). This evidence concerns the gene PPARGC1A and stroke disorder.
