Figure 1. Analysis of tumor infiltrating macrophages (TAM) in glioma. (A) Heatmap was drawn to depict the TAM in glioma from the TCGA merged GBMLGG cohort. (B) TAMs were increased in GBM in the TCGA merged GBMLGG, CGGA mRNAseq-693 and CGGA mRNAseq-325 cohorts, respectively. (C) Kaplan-Meier overall survival curves displayed that increased TAM was related to the poor prognosis and lower survival rate of glioma. *, P< 0.05; **, P< 0.01; ***, P< 0.001, ****, P< 0.0001.
