| Outline of Final Research Achievements |
In vivo biological functions of a non-neuronal cardiac cholinergic system (NNCCS) was investigated using the heart-specific ChAT tg mice (ChAT tgm), in which choline acetyltransferase (ChAT) gene was overexpressed under the control of an alpha MHC promoter. ChAT tgm showed comparable hemodynamic parameters and cardiac functions, compared with WT mice. ChAT tgm was resistant against myocardial infarction with a remarkably improved survival rate, more intact myocardium in the infarcted area as well as enhanced angiogenesis, and more glucose uptake in cardiomyocytes, compared with WT mice. Isolated ChAT tgm hearts showed a longer beating period even in the global ischemia and faster recovery of beating after ischemia canceled. These results suggest that NNCCS can be a therapeutic target against cardiovascular diseases.
