Systems biology of the heart

Abstract: Models of the heart have been developed since 1960, starting with the discovery and modeling of potassium channels. The first models of calcium balance were made in the 1980s and have now reached a high degree of physiological detail. During the 1990s, these cell models have been incorporated into anatomically detailed tissue and organ models. Systems biology of the heart is now well developed and is proving increasingly useful in unraveling complicated physiological functions and in understanding disease stat… Show more

“…Because adaptation may involve various aspects of regulation, target validation ideally should integrate not only metabolic, but also signalling and gene‐expression networks (Alberghina and Westerhoff, 2005). So far, however, of the few successful network‐based drug design studies that exist (Noble, 2006), none addresses the potential adaptation of the network.…”

“…Despite the significant progress that has been made in the development of computational atrial cardiomyocyte models and their application to study AF mechanisms, numerous challenges remain. The present modelling approach reflects a ‘middle‐out approach’ (Noble, ), in which most models have an intermediate level of complexity (i.e. deterministic common‐pool models to simulate APs and whole‐cell Ca 2+ transients), corresponding to the amount of available experimental data (Fig.…”

“…To create the hierarchical, multiscale understanding of AF that is needed to optimally develop novel antiarrhythmic therapies, models will also have to be extended from this cellular level in both subcellular and multicellular directions (Noble, ), and will have to cover a larger range of time scales (Fig. B ).…”

“…For the actual construction of a model, three major directions of discovery have been formulated: bottom‐up, top‐down and middle‐out (term credited to Sydney Brenner, in Noble76). For dynamic models, the bottom‐up approach is still prevalent, thanks to the complexity of the systems and to the fact that even the behaviour of individual pathways is rarely understood.…”
