Fig. 2
Cluster analysis of gene expression profiles after treatment with CCl4. Gene expression profiles represent up-regulated genes (red) and down-regulated genes (green) after treatment with CCl4. Increasing red intensity denotes genes whose expression increased with respect to vehicle, and green intensity denotes genes that decreased in expression with respect to vehicle. Each row denotes a single gene and each column represents an individual dose. The color scale shown indicates the ratios of the signal for CCl4 (Cy5 signal, red) to that for the vehicle (Cy3 signal, green) (color figure online)
