CS exposure effects on frontal lobe expression of transcription factor genes. The mRNA levels of FOXO1 (Forkhead Box O1) (A), FOXO4 (Forkhead Box O4) (B), Olig1 (Oligodendrocyte transcription factor 1) (C), Olig2 (Oligodendrocyte transcription factor 2) (D), NKX2-2 (NK2 Homeobox 2) (E), NKX6-1 (NK6 Homeobox 1) (F), PAX6 (Paired box 6) (G), and SOX9 (Sex determining region Y-Box 9) (H) were measured using targeted PCR arrays, and results were calculated using the ΔΔCt method after normalizing to HPRT1. Inter-group comparisons were made by one-way ANOVA (Table 1) with the Tukey post-test (*p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001).
