In order to explore the role of circLONP2/miR-584-5p/YAP1 axis n the regulation of malignant phenotype of BC cells, we transfected an inhibitor of miR-584-5p into T24 and 5637 cells, which could significantly lower the expression level of miR-584-5p (Figure 5(a)). Here, YAP1 is linked to breast cancer.
