Abstract

Analysis of the dynamics of adenosine triphosphate (ATP) is vital to quantitatively define the actual roles of ATP in biological activities. Here, we applied a genetically encoded Förster resonance energy transfer biosensor “GO-ATeam” and created a transgenic mouse model that allows systemic ATP levels to be quantitatively, sensitively, noninvasively, and spatiotemporally measured under physiological and pathological conditions. We used this model to readily conduct intravital imaging of ATP dynamics under three different conditions: during exercise, in all organs and cells; during myocardial infarction progression; and in response to the application of cardiotoxic drugs. These findings provide compelling evidence that the GO-ATeam mouse model is a powerful tool to investigate the multifarious functions of cellular ATP in vivo with unprecedented spatiotemporal resolution in real-time. This will inform predictions of molecular and morphological responses to perturbations of ATP levels, as well as the elucidation of physiological mechanisms that control ATP homeostasis.
