Ingenuity Pathway Analysis toxicity analysis. The genes showing differential expression upon exposure to current + GFP are not significantly involved in any type of toxicity. The bar chart shows the percentage of genes involved in each type of toxicity (left axis). Numbers above the bars are the number of genes that would equate to 100% for each type of toxicity. The orange points show the -log(P-value) (right axis) for each category, and thus indicate whether a significant number of genes are found within a category to suggest an actual toxicity affect. A -log(P-value) of 1.3 would be considered significant; all -log(P-values) are lower than 1.3 and therefore not significant.
