CS exposure effects on frontal lobe expression of immature oligodendroglial genes. mRNA levels of Nestin (A), Vimentin (B), CNP (2′,3′-cyclic nucleotide 3′ phosphodiesterase) (C), PDGFR-α (Platelet Derived Growth Factor Receptor, alpha polypeptide) (D), GalC (galactocerebrosidase) (E), and PROM 1 (Prominin 1) (F) were measured using targeted PCR arrays. Gene expression was calculated using the ΔΔCt method with results normalized 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, ξ0.05 < p < 0.10).
