The Molecule Pages from UCSD Signaling Gateway have been regularly published online since one decade and are now printed biannually. As a researcher involved in biomathematical and biomechanical modeling and simulation, I found these pages very informative, either when dealing with biological processes happening at the nano- and microscopic scales, or incorporating these events in a meso- and macroscopic scale modeling to enhance reductionist models when necessary. UCSD Molecule Pages indeed yield information that enables interdisciplinary research and I have cited the Molecule Pages over 130 times in my recent book ‘Intracellular Signaling Mediators in the Circulatory and Ventilatory Systems’ (Springer New York, 2013).
