Figure 1. RTK/Ras/PI3K/AKT pathway was strongly related to immune functions in glioma. (A) GO analysis showed that RTK/Ras/PI3K/AKT pathway was involved in immune response and inflammatory response. (B) Volcano plot display differentially expressed cytokines and chemokines according to RTK/Ras/PI3K/AKT signaling. Heat maps display the association between RTK/Ras/PI3K/AKT pathway, and most correlated gene expression in the immune response (C) and inflammatory response (D).
