The downstream signaling pathway of KIF23. (A) Knockdown of KIF23 suppresses EMT, and overexpression of KIF23 promotes EMT. (B) Knockdown of N-cadherin inhibits proliferation of TNBC cells, and overexpression of N-cadherin promotes proliferation of TNBC cells. (C) Transwell assays (×100) indicate that knockdown of N-cadherin inhibits migration of TNBC cells, and overexpression of N-cadherin promotes migration of TNBC cells. *P<0.05, **P<0.01, ***P<0.001. All experiments were repeated three times.
