CS exposure effects on frontal lobe neuronal/glial gene expression in the temporal lobe. CSPG4 (Chondroitin sulfate proteoglycan 4) (A), GFAP (Glial fibrillary acidic protein) (B), NCAM (neural cell adhesion molecule 1) (C), NRTK2 (Neurotrophic receptor tyrosine kinase type 2) (D), GPD1 (Glycerol-3-phosphate dehydrogenase 1 (Soluble)) (E), GPD2 (Glycerol-3-phosphate dehydrogenase 2 (mitochondrial)) (F), and GSTP1 (Glutathione S-transferase pi 1) (G), mRNA levels were measured using custom targeted PCR arrays. 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).
