Furthermore, E-cadherin expression was significantly decreased, N-cadherin and Vimentin were increased by sh-hsa_circ_0139402, and hsa-miR-326 inhibition could significantly decrease E-cadherin expression and increase N-cadherin and Vimentin expression (Figure 4(d)); however, hsa-miR-326 inhibition could neutralize the expression of EMT biomarker cotransfected with sh-hsa_circ_0139402 in BC cells (Figures 4(e) and 4(f)). Here, CDH2 is linked to breast cancer.
