Figure 6. Toxicity effects of differentially expressed proteins in hTERT-BJ1 fibroblasts treated with azathioprine or taxol compared to vehicle-treated cells. Ingenuity Pathway Analysis showed toxicity functions significantly enriched by the proteins differentially expressed in hTERT-BJ1 fibroblasts treated with azathioprine or taxol (P < 0.05). The p value for each pathway is indicated by the bar and is expressed as −1 times the log of the p value.
