2. The NGF signaling pathway of the previous slide is only one of many components of a signal transduction network in mammalian cells, which integrates and processes information from growth factors, anti-growth factors, death factors, cell-cell and cell-matrix adhesions, etc., resulting in changes in gene expression, cell proliferation or cell cycle arrest, or cell death (apoptosis). How are we to understand the signal processing carried out by a network of this complexity? Is the wiring diagram sufficient to account for the physiological attributes of mammalian cells in vitro or in vivo? If not, what is missing?
