Calycosin suppresses breast cancer cell migration and invasiveness by inhibiting EMT. (A) Western blot analysis shows relative levels of CD147, MMP-2, MMP-9, E-cadherin, N-cadherin, and Vimentin proteins in control and calycosin-treated T47D and MCF-7 breast cancer cells. (B) Western blot analysis shows relative levels of CD147, MMP-2, MMP-9, E-cadherin, N-cadherin, and Vimentin proteins in T47D and MCF-7 breast cancer cells treated with different concentrations of TGFβ1. (C) Representative images of wound healing assay at 0 and 24 h show migration ability of T47D and MCF-7 breast cancer cells treated with calycosin, TGFβ1, or calycosin plus TGFβ1. (D) Transwell invasion assay results show the invasiveness of T47D and MCF-7 breast cancer cells treated with calycosin, TGFβ1, or calycosin plus TGFβ1. The data were represented as means ± SD. *P<0.05; **P<0.01; ***P<0.001.
