We further explored the associations between STEAP3 expression and classical macrophage phenotype in the TCGA-GBMLGG cohort with Spearman’s rank correlation test, including gene expression of M0 (undifferentiated) marker (AIF1), M1 (anti-tumor) markers (IL12A, TNF, NOS2, PTGS2) and M2 (tumor-promoting) markers (IL10, CD163, TGFB1, CSF1R). Here, IL10 is linked to neoplasm.
