Figure 3.
Effects of 30 μM dieldrin exposure on expression of genes encoding proteins for: (A) 5HT synthesis, storage and degradation, (B) 5HT receptors. Results are shown for cells undergoing NGF-induced differentiation. Asterisks shown below each gene denote a significant main treatment effect. Daggers denote genes for which treatment interacted with time and show the individual values for which treatment effects were present. Multivariate ANOVA indicates a main effect of treatment (p < 0.0003) and interactions of treatment × gene (p < 0.0001) and treatment × gene × time (p < 0.0003).
