Principles of Cell Signaling and Biological Consequences
Group B: Discussion Question 2
31 January 2005
The kinetics of MAPK activation plays an important role in determining the biological outcomes of upstream signals. For example, although epidermal growth factor (EGF) stimulates a transient activation of MAPK, nerve growth factor (NGF) triggers a more sustained stimulation. Speculate on the molecular mechanisms involved in causing this divergence in signaling. Also, what are your thoughts on how this difference in MAPK activation can lead to such drastic differences in biological outcomes - proliferation verse differentiation?
