In the GC sample cohort from the TCGA (Stomach adenocarcinoma (TCGA, Firehose Legacy, n = 478)), the levels of several markers for macrophages (FN1, MRS1, CD68, and CCL7), blood vessels (CDH5) and lymphatic vessels (VEGFC) exhibited positive correlations with TGM2 expression (Fig. S8). Here, TGM2 is linked to adenocarcinoma.
