Figure 1. Identification of HCC-specific gene list. (A) Overview of the overall design and analytic procedure of the study. (B) Relative expression of all the included sample before (Upper & Red) and after (Lower & blue) RMA normalization. All the expression value was transformed by “log2()” algorism. (C) Venn diagram among three lists of dysregulated genes between three different subtypes of liver cancer (HCC, ICC and MLC) and normal liver. 1103 HCC-specific genes, 2963 ICC-specific genes and 1640 MLC-specific genes were generated through Venn selection.
