The results of this analysis were used to construct a heatmap using unsupervised hierarchical clustering, which revealed that luminal tumors have a characteristic lncRNA expression profile, and some differentially expressed lncRNAs include GATA3-AS1, LINC01016, and DSCAM-AS1, which were previously identified in luminal breast cancer cell lines (Figure 3), and an additional lncRNA, MAPT-IT1, which was found to be overexpressed in luminal breast cancer patients (Figure 5). This evidence concerns the gene MAPT and breast cancer.
