Figure 8. Validation of the expression characteristics of angiogenic genes. (A) Genetic alteration detection of the angiogenic genes in the TCGA HCC cohort. (B–E) Expression levels of angiogenic genes in HCC and normal samples in the TCGA HCC cohort. (F–I) Expression levels of angiogenic genes in HCC and normal samples in the TCGA HCC cohort. (J) The imagines showed the expression patterns of the angiogenic genes in HCC tissues and normal liver tissues. (K–N) The expression profiles of the angiogenic genes in multiple types of HCC cell lines.
