Fig. 7From: Identification of novel prognostic targets in glioblastoma using bioinformatics analysisPrincipal component analysis between the GBM and LGG or non-tumor brain tissue groups based on screened prognostic-related genes. PCA 2D scatter plots and scree plots showed within-sample variation between GBM and brain-cortex (A), brain-hippocampus (B) or LGG (C) based on screened prognostic-related gene set.
