Figure 9. Suggested architecture of PRL-R signaling network with potential routes of MAPK activation in breast cancer cells.
Solid lines with arrows show the activation or phosphorylation of proteins. Dotted lines indicate the formation of phosphatidylinositol-trisphosphate (PIP3) by PI3-kinase. Solid lines with circular ends represent protein-protein and protein-lipid interactions. Thick solid lines show prevailing routes of ERK1/2 activation.
