Abstract excerpt

Previous studies have demonstrated a diminution in the bioactivity of the guanine nucleotide-binding regulatory protein that stimulates adenylyl cyclase (Gs) in hearts of the hypertrophic BIO 14.6 Syrian hamster. In this study, we measured functional activity and immunodetectable levels of Gs in a mutant strain of hamsters (BIO 53.58) that develop a dilated cardiomyopathy. Pathological studies demonstrated that...
