epinephrine inhibits the a ctivity of phosph atidate phosphohydrolase of isolated huma n hepatocytes
the effect of epinephrine on phosphatidate phosphohydrolase (pap) activity of isolated human hepatocytes was studied. epineprine inhibited the enzyme activity progressively at concentrations above 0.1 µm, reaching a maximum inhibition of 64.5% at 100 µm concentration. inclusion of alprenolol, a β-receptor blocker, in the incubation mixture abolished the inhibitory effect of epinephrine on pap, ...
OBJECTIVE Sustained β-adrenergic stimulation is a hallmark of sympathetic hyperactivity in cardiovascular diseases. It is associated with oxidative stress and altered vasoconstrictor tone. This study investigated the β-adrenoceptor subtype and the signaling pathways implicated in the vascular effects of β-adrenoceptor overactivation. METHODS AND RESULTS Mice lacking the β1- or β2-adrenoceptor...
Diabetic patients have a decreased incidence of acute respiratory distress syndrome, but the mechanism responsible for the decreased incidence is uncertain. Reabsorption of alveolar edema fluid (alveolar fluid clearance) has been considered to play an important role in resolution of acute respiratory distress syndrome. However, little is known regarding alveolar fluid clearance in diabetes mell...
β-blockers are widely used to improve symptoms and prolong life in heart disease primarily by inhibiting the actions of endogenous catecholamines at the β1-adrenoceptor. There are two common naturally occurring polymorphisms within the human β1-adrenoceptor sequence: Ser or Gly at position 49 in the N-terminus and Gly or Arg at position 389 in the C-terminus and some clinical studies have sugge...
