IHC analysis of the protein expression of m6A-related molecules in GC and normal tissues. (A) Representative IHC staining of m6A-related “writers” in GC and normal tissues in TMA cohort. (B) Comparison of the relative expression of m6A-related “writers” between GC and normal tissues in TMA cohort. (C) Representative IHC staining of m6A-related “readers” in GC and normal tissues in TMA cohort. (E) Comparison of the relative expression of m6A-related “readers” between GC and normal tissues in TMA cohort. (D) Representative IHC staining of m6A-related “erasers” in GC and normal tissues in TMA cohort. (F) Comparison of the relative expression of m6A-related “erasers” between GC and normal tissues in TMA cohort. (N-normal, T-tumor, *P<0.05, **P<0.01, ***P<0.001, N.S: no significance).
