Elevation of cyclic AMP (cAMP) content in perfused rat hearts by exposure to glucagon, forskolin, and 1-methyl-3-isobutylxanthine (IBMX) increased rates of protein synthesis during the second hour of perfusion with buffer that contained glucose in the absence of added insulin. When tetrodotoxin was added to arrest contractile activity, glucagon, forskolin,(More)
A modification of the Langendorff technique for perfusion of rat hearts was developed to allow a constant intraventricular pressure to be imposed on the left ventricle of arrested-catheterized hearts. This model was used to assess effects of increased aortic (60 and 120 mmHg) and intraventricular (0 and 25 mmHg) pressures on the rate of protein synthesis(More)
