Cardiac physiology in transgenic mice. Circ Res 1998 Mar 09;82(4):407-15 PMID: 9506700


By use of gene targeting and/or transgenesis, it is now possible to make defined changes in genes whose functions underlie mammalian cardiovascular function. Because of technical and economic considerations, these experiments are largely confined to the mouse. Genetic modification of the loci responsible for aspects of cardiac development, differentiation, and function via gene targeting, as well as modulation of the cardiac protein complement using transgenesis, has begun to provide mouse models of cardiac hypertrophy, dilated cardiomyopathy, and hypertrophic cardiomyopathies. In order to use these animal models fully and explore their phenotypes at the whole organ and whole animal levels, the extension of cardiovascular physiological methodologies to the mouse is imperative. Techniques for exploring aspects of cardiovascular function are well developed for larger animal models, but their modification for the small size of the mouse heart and for the animal's rapid cardiac cycle has proven to be a formidable challenge, requiring the combined efforts of the molecular biology, physiology, and cardiology communities. We review here the ability of present-day technology to obtain reproducible data on murine cardiac function at the whole organ and animal levels.
