Figure 1
Hierarchical clustering analysis of genes differentially regulated by PCB 153. Analysis was performed based on log2-transformed ratio values of 160 genes differentially regulated, between the 8 m/kg BW PCB 153 dose and control groups. Rows represent genes and columns represent samples. Samples: Cont, Control; 0.5 mg, 2 mg and 8 mg indicate, 0.5, 2 and 8 mg/kg BW PCB 153, respectively. Color bar indicates log2-transformed ratio values and corresponding colors (red, black and green for up-regulated, not changing and down regulated, respectively).
