MUC1 and glioblastoma: Interestingly, we observed an overall significantly positive correlation between the expression of FABP7 and its modulated genes (ENO1, MUC1, COL5A1, and IL11) and the infiltration of immunosuppressive cells (Tregs, CAFs, and MDSCs) relative to anti-tumor immune cells (CD8+ T cells, CD4+ T cells, and macrophages) in LGG compared to GBM (Figure 4A).
