In addition, we also found a positive correlation between the CNVs of YTHDF2 and the tumor infiltrating lymphocytes (TILs) (Supplementary Figure S8A), immunostimulants (Supplementary Figure S8B), immunosuppressants (Supplementary Figure S8C), MHC (Supplementary Figure S8D), chemokines (Supplementary Figure S8E), and chemokine receptors (Supplementary Figure S8F), especially in CHOL, KICH, and LGG. Here, YTHDF2 is linked to neoplasm.
