Regarding paired tumor lesions and normal tissues samples in the pan-cancer database, TGM3 was expressed at high levels in bladder urothelial carcinoma (BLCA), breast invasive carcinoma (BRCA), PRAD, KIRP, LIHC, KIRC and LUSC (Figures 4A–G), but it was expressed at low levels in THCA and KICH (Figures 4H,I). This evidence concerns the gene TGM3 and invasive breast carcinoma.
