ERBB2 and breast carcinoma: We identified 3,514 coding genes and 96 lncRNAs, 3,181 coding genes and 87 lncRNAs, 2,198 coding genes and 60 lncRNAs, and 2,841 coding genes and 70 lncRNAs differentially expressed in TN, HER2, luminal A, and luminal B breast cancers compared to normal tissues (Figure 2).
