Our group has developed novel fluorescent analogs of GHSR ligands to reveal changes in the dynamics of myocardial GHSR during cardiomyocyte differentiation [25], in a mouse model of diabetic cardiomyopathy [26], and in human myocardial tissue before and after cardiac transplantation [27] and heart disease [28]. This evidence concerns the gene GHSR and diabetic cardiomyopathy.
