Compared to SV-HUC-1, the relative expression level of PVT1 was up-regulated in both BC cells, T24 about 3.76 times (P < 0.001) and UM-UC-3 about 2.84 times (P=0.004) (Figure 1E), and the relative expression level of miR-194-5p was decreased in both BC cells, T24 about 44.16% (P=0.003) and UM-UC-3 about 63.77% (P = 0.001) (Figure 1F). Here, PVT1 is linked to breast cancer.
