Journal ArticleDOI

Decreased bioactivity of the guanine nucleotide-binding protein that stimulates adenylate cyclase in hearts from cardiomyopathic Syrian hamsters

TL;DR: It is concluded that a functional defect in alpha Gs may contribute to a contractile abnormalities in the cardiomyopathic BIO 14.6 hamster, however, the etiology of thealpha Gs defect remains obscure.
Journal ArticleDOI

Regulated Overexpression of the A1-Adenosine Receptor in Mice Results in Adverse but Reversible Changes in Cardiac Morphology and Function

TL;DR: The inducible A1-AR transgenic mouse model provides novel insights into the role of adenosine signaling in heart failure and illustrates the potentially deleterious consequences of selective versus nonselective activation of adenoine-signaling pathways in the heart.
Journal ArticleDOI

Immunodetectable levels of the inhibitory guanine nucleotide-binding regulatory proteins in failing human heart: discordance with measurements of adenylate cyclase activity and levels of pertussis toxin substrate.

TL;DR: Although functional activity of alpha Gi was increased in the particulate fractions of the failing heart as measured by inhibition of guanine nucleotide-stimulated adenylate cyclase activity, there were not associated changes in the levels of immunodetectable Gi.
Journal ArticleDOI

Effects of soluble TNF receptor treatment on lipopolysaccharide-induced myocardial cytokine expression

TL;DR: Inability to block myocardial expression of IL-6 and MCP-1 suggests a possible mechanism for the failure of anti-TNF therapies in the treatment of endotoxin shock, and differentially altered the cytokine expression in the plasma and myocardium during endotoxemia.
