The relationship between PI3K/Akt mutations and immune microenvironment. (a) CIBERSORT comparison of the content of 22 types of immune cells in the tumor microenvironments of PI3K/Akt-MT and PI3K/Akt-WT patients (algorithm running the lm22 signature and 1,000 permissions). (b) Difference in immune checkpoint gene expression between the PI3K/Akt-WT and PI3K/Akt-MT groups. (c) Difference in immune fractions between the PI3K/Akt-WT and PI3K/Akt-MT groups. (d) The functions of immune module genes involved in the PI3K/Akt pathway, including antigen presentation, CD8+ T cells, cytologic activity, inhibition, NK cells, stimulation, and type I IFN (; ; ; ; Mann–Whitney test).
