Venn diagram of differently expressed genes (DEGs) from three comparisons. Venn diagram of differently expressed genes (DEGs) from three comparisons: Cancer/Normal (C/N), Pericancerous/Normal (P/N) and Cancer/Pericancerous (C/P). A. Venn diagram of all DEGs from three comparisons. The purple number in the center showed the number of DEGs appeared in all three comparisons. B. Venn diagram of up-regulated DEGs from three comparisons. The red number in the center showed the number of DEGs appeared in all three comparisons. C. Venn diagram of down-regulated DEGs from three comparisons. The blue number in the center showed the number of DEGs appeared in all three comparisons. D. The log2-fold-change of DEGs in centers of subgraph A, B and C. The DEGs in red were appeared in the centers of subgraph A and B. The DEGs in blue were appeared in the centers of subgraph A and C. The DEGs in purple was only appeared in the center of subgraph A.
