Specifically, it showed a positive correlation between ENG expressions and immune lymphocytes (Figure 4A), immunoinhibitors (Figure 4B), immunostimulators (Figure 4C), major histocompatibility complex (MHC) molecules (Figure 4D), immuno-chemokines (Figure 4E), or immuno-receptors (Figure 4F) across most tumor types. This evidence concerns the gene HLA-C and neoplasm.
