As shown in Figure 7, SNAI2 was positively associated with the infiltration levels of CAF, Endo, Neutrophil, Monocyte, Macrophage, Gran, and HSC, and negatively associated with the infiltration levels of B cell plasma in most TCGA cancers, especially in BRCA, HNSC, TGCT. This evidence concerns the gene SNAI2 and cancer.
