Fig. 5. Principal component analysis of samples for TCGA.
(A) PCA shows samples divisibility from the low risk- and high-risk group based on all gene expression. (B) PCA shows samples divisibility from the low risk- and high-risk group based on immune gene expression. (C) PCA shows samples divisibility from the low risk- and high-risk group based on immune lncRNA expression. (D) PCA shows samples divisibility from the low risk- and high-risk group based on lncRNA signature expression.
