Figure 4.

Western blot assay of growth associated protein 43 (GAP-43) in the hippocampal dentate gyrus of postnatal day 21 weaning rats.

The gray value ratio of GAP-43 to β-tubulin in each group was measured. The ratio in the control group was set as a reference, and then all experimental ratios were compared with the control group. GAP-43 expression was decreased following acrylamide (ACR) administration. *P < 0.05, **P < 0.01, vs. control group (mean ± SD, n = 8, one-way analysis of variance followed by Tukey post hoc test).
