When we estimated correlations between the expressions of the 33 significant genes and the infiltrations of the eight immune cells from the 525 GBM tissues, there were significant correlations (p < 0.01) between the expressions of the 32 genes and the CD8+ T-cell infiltrations, except for the ATP5C1 gene (an x in the box indicates a p-value ≥ 0.01) (Fig 2F). This evidence concerns the gene ATP5F1C and glioblastoma.
