The GO terms such as metabolism, transport, cellular proliferation, apoptosis, adhesion, angiogenesis, etc. were chosen. Meanwhile,

some other genes were associated with oxidative stress, immune response and inflammatory response. Table 2 The deregulated DEGs sharing from cirrhosis to metastasis stage classified by the following screened GO.

The word ’4 group’ means the DEGs sharing for the above 4 stages of liver tissues. The numbers up and down the line indicate the number of up-regulated and down-regulated DEGs respectively. The histological changes during the hepatocarnogenesis in DEN-treated rat models were similar to those seen in humans, including non-specific damage, fibrosis, cirrhosis, dysplastic nodules, early tumorous nodules, progression

Clomifene and metastasis, which appeared to be sequential events. The processes of chronic inflammation, fibrosis and cirrhosis are closely related to liver cancer, while cirrhosis was considered as the precancerous lesions. Therefore, the co-expression of deregulated genes among these four stages might suggest they play key roles in the development of hepatocellular eFT-508 ic50 carcinoma. Among upregulated DEGs sharing from cirrhosis to metastasis, there were 246 known genes, 39 translocation loci, 51 inferred genes and 13 unkown genes; while among downregulated DEGs sharing from cirrhosis to metastasis, there were 215 known genes, 48 translocation loci, 63 inferred genes and 19 unkown genes (see additional file 1). Cellular proliferation, apoptosis, adhesion, migration and agiogenesis all play important roles in carcinogenesis.
