To explore the role of lncRNA in TNBC, we analyzed the TCGA datasets of lncRNA expressional profiles of TNBC vs. non-TNBC subtypes (Figure 1A) and breast cancer vs. normal tissue (Figure 1B) and we identified that lncRNA MNX1-AS1 was the only candidate upregulated over 5-fold in TNBC and breast cancer (Figure 1C). Here, MNX1 is linked to breast cancer.
