Figure 2.Silencing of MAP2K4 inhibits proliferation, migration, and invasion of breast cancer cells. (A) and (B),Two siRNA sequences were transfected to knockdown MAP2K4 expression in MCF-7 and MDA-MB-231 cells. MAP2K4 expression was detected with qRT-PCR and Western blot in MAP2K4-silenced breast cancer cells, normalized to GAPDH or β-actin. Mean ± SD,**P<0.01. Cell proliferation, migration, and invasion were measured by MTT assays (C), EdU assays (D), Transwell (E) and Boyden assays (F). Mean ± SD, *P<0.05; **P<0.01; ***P<0.001.
