Figure 4. Inhibiting p-PI3K expression reduces cell proliferation, migration, and invasion in MAP2K4-overexpressing breast cancer cells. MTT assays (A), EdU incorporation assay (B) and Transwell (C) and Boyden assays (D) of breast cancer cells were conducted after inhibiting p-PI3K expression. Mean ± SD, *P<0.05; **P<0.01; ***P<0.001.
