Figure 3. MAP2K4 activates PI3K/AKT and its downstream cell cycle and EMT signals. Western blot analysis of proteins in response to overexpressed MAP2K4 in MCF-7 and MDA-MB-231 cells. (A) PI3K, p-PI3K, AKT, p-AKT, c-JUN, c-Myc and CCND1 protein sequences, (B) the invasion and migration associated proteins, E-cadherin, N-cadherin, Slug, and Vimentin were measured.
