The phosphatidylinositol 3-kinase (PI3K)/Akt and mitogen/extracellular signal-regulated kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathways are important integrators of growth and survival signals originating from extracellular stimuli. We assessed the importance of these signaling pathways in the growth and survival of 8 breast cell lines (MCF10A, an immortalized line; and 7 cancer cell lines). The cell lines expressed variable levels of both phosphorylated ERK and… CONTINUE READING
