A comparable expression pattern was observed in a different dataset from GSE65194 (41 TNBC, 30 HER2-enriched breast cancer, and 29 luminal A and 30 luminal B breast cancer; Fig. S1a), METABRIC (199 TNBC; 220 HER2-enriched breast cancer; and 279 luminal A and 461 luminal B breast cancer; Fig. S1b), and SMC (36 TNBC; 18 HER2-enriched breast cancer; and 47 luminal A and 65 luminal B breast cancer datasets; Fig. S1c). This evidence concerns the gene ERBB2 and breast carcinoma.
