Myosin light-chain kinase (MLCK) plays a crucial role in the cell migration and tumor metastasis. Herein, we investigated the signaling pathways involved in MLCK using ML-7, a specific inhibitor of MLCK, in breast cancer cell proliferation and migration. Our data showed that reduction of MLCK in breast cancer cells mediated by 20 mu M ML-7 was able to depress the cell proliferation and migration using two parallel cell lines (MCF-7 and LM-MCF/MDA-MB-231) with different metastatic abilities through reciprocal cross-talk with activated ERK1/2, in which both phosphorylated myosin light chain (p-MLC) and cascades of beta-catenin, cyclin 131, survivin, and c-Myc serve as essential downstream effectors.
