Modulation of c-fos and c-myc Expression by Effectors of Ion Movements
The role of ion movements in signal transduction and macromolecular biosynthesis has been well substantiated. For example, Ca2+ mobilization is an essential component of growth factor signaling where there is an involvement of protein kinase C. K+ movements, mediated by the Na+ , K+ -ATPase membrane pump, are necessary not only for maintaining the membrane potential gradient but also for macromolecular synthesis, i.e., protein synthesis and subsequent DNA replication.
