Significant overall effect of lead exposure without a significant difference between male and female gene responses. A. Hierarchical cluster analysis of differentially expressed genes in hippocampus from control and lead exposed female or male rats. Green indicates down-regulation of a gene; red indicates up-regulation relative to the median. B. Scatter plot comparing male and female average gene expression responses. This set of genes did not show a significant sex-based differential response to lead exposure. C. Multi-dimensional scaling analysis of the gene expression shown in panel A. Color legend is the same as in Figure 2.
