Hierarchial clustering of screened differential expressional genes. (A) hierarchical clustering of 694 deregulated genes shared in liver tissues of DEN-treated rats from cirrhosis tissues at the 12^th week, dysplastic nodules at the 14^th week, early cancerous nodules at the 16^th week, and cancerous nodules with lung metastasis at the 20^th week, respectively. (Red, a high expression level as compared with the mean; green, a low expression level as compared with the mean). (B) the dendrogram of the 246 upregulated known genes shared in the liver tissues of four chips is magnified. (C)the dendrogram of the 215 downregulated known genes shared in the liver tissues of four chips is magnified.
