Meanwhile, the top 20 up-regulated genes are shown in Fig. 4C. Due to the tumor-suppressive role of MIDEAS-AS1 in TNBC, we integrated the down-regulated genes in breast cancer tissues from TCGA database and the up-regulated genes after MIDEAS-AS1 overexpression in TNBC cells, and then, 9 candidate genes were selected as potential downstream targets of MIDEAS-AS1 (Fig. 4D). Here, MIDEAS is linked to breast cancer.
