In addition, the CIBERSORT algorithm (Figure 4F) and the enrichment analysis of 23 immune cells (Figure 4G and Supplementary Figure S1D) showed that the infiltration levels of B cells, CD8 T cells, and M1 tumor-associated macrophages in the low-m6A-IS group were significantly higher than those in the high-m6A-IS group. The gene discussed is CD8A; the disease is neoplasm.
