Cellular signaling pathways are not isolated from each other but arexa0 interconnectedxa0 toxa0 formxa0 complexxa0 signalingxa0 networks. Cells receive information from many different growth factor receptors and from cell-matrix and cell-cell contacts. They must then inte- gratexa0 thisxa0 informationxa0 toxa0 regulatexa0 diversexa0 processes,xa0 suchxa0 as protein synthesis and cell growth, motility, cell architecture and polarity, differentiation, and programmed cell death. The same signalingx...
