Figure 3From: Characteristic gene expression profiles in the progression from liver cirrhosis to carcinoma induced by diethylnitrosamine in a rat modelTotal RNA isolated from the liver tissues of the rats was identified by agar electrophoresis. (A) from normal rats; (B-E) from DEN-treated rats: cirrhosis tissue at 12th week (B), dysplastic nodules at the 14th week (C), early cancerous nodules at the 16th week (D), cancerous nodules with lung metastasis at the 20th week (E).Back to article page
