Figure 2

Heat map of hepatic gene expression signature for TCDD, PCB126 and PCB153. Heat map depicting hepatic gene expression signatures in female Sprague-Dawley rats exposed to TCDD, PCB126 and PCB153. The expression signature for each compound represents genes differentially expressed (≥2-fold change) following both 13 and 52 weeks of exposure.
