The migration and invasion activities in vitro and the expression of EMT-associated molecules in triple-negative breast cancer cell lines. Triple-negative breast cancer (TNBC) cell lines MDA-MB-231, MDA-MB-468, Hs578T, and HCC1937 were cultured and in vitro activities of (A) migration and (B) invasion were performed as described in Materials and Methods. (C) The protein expressions of EMT-associated molecules in TNBC cell lines were inspected by Western blotting analyses. Data are presented for at least triplicate experiments, and results are represented as the mean ± S.D. Different lowercase letters represent significant differences between the two groups when p < 0.05.
