TGFB1 and glioma: The cytokines levels to FTL enrichment based on Rembrandt and TCGA-glioma databases were analyzed, and the gene expressions of IL-10 and TGFB1 in the high-FTL group was significantly higher than that in the low-FTL group (Figure S9B, C, E, F), while the gene expressions of IL-12A in the high-FTL group was significantly lower than that in the low-FTL group in the TCGA-glioma database (Figure S9B, C).
