| Outline of Final Research Achievements |
We have defined a structured language, Physiological Hierarchy Markup language (PHML), for describing computational models in the field of systems biology and physiology. We have also developed a versatile open platform (PhysioDesigner and Flint) for multilevel modeling and simulation of physiological systems described by the PHML.
We have carried out experimental and simulation studies on the mechanism determining the rhythm of the heart beat and arrhythmias. Physiological or pharmacological changes of cardiac ion channels, such as G protein-gated potassium channel and hERG channel, in vitro, were measured, and the obtained data were integrated into theoretical model of cardiac action potential. This made it possible to predict the effects of these changes on the cardiac function. Through these studies, we have demonstrated that the ion channel function and regulation as well as its localization in the cardiomyocyte were crucial importance to predict changes in the cardiac function.
