RBFOX3 and post-traumatic stress disorder: As the result indicated, although treadmill and treadmill combined with catalpol both improved the density of the BrdU+ cell as well as the BrdU and NeuN dual positive cell (Figure 5F–5H; one-way ANOVA, BrdU+, treadmill vs. PTSD: p < 0.001; BrdU+/NeuN+, treadmill vs. PTSD: p < 0.001), catalpol treatment did not result in any significant difference on the density of BrdU+ cell in compared with treadmill treatment (Figure 5F–5H; one-way ANOVA).
