Cardiac pathologies and aging: lessons from a tiny heart

ARTabstract
The high level of conservation of the cardiogenic gene regulatory network as well as of the cellular and physiological characteristics of the cardiomyocytes between fly and human, makes the small heart of this invertebrate the simplest and most flexible genetic system to dissect the fundamental molecular mechanisms that are brought into play during the development, the establishment and the maintenance of the cardiac function. The recent improvements in techniques of measurements of cardiac function made it possible to validate Drosophila as a model of cardiomyopathies and arrhythmias of genetic and metabolic origin or dependent of ageing. The heart of the fly thus represents a model of choice to identify genes and their interactions implicated in cardiac pathologies.
