induction of cardiac hypertrophy by isoproterenol treatment revealed a marked protective effect of the kallikrein transgene because the cardiac weight of tgr(hklk1) increased significantly less, and the expression of atrial natriuretic peptide and collagen iii as markers for hypertrophy and fibrosis, respectively, were less enhanced. |

these results suggest that the decreased expression of g(s)alpha proteins may not be the cause but the effect of hypertrophy and that the diminished responsiveness of adenylyl cyclase to gtpgammas, isoproterenol, naf, and forskolin in hearts from av shunt rats may partly be due to the decreased expression of g(s)alpha. |

Altered phosphorylation of sarcoplasmic reticulum contributes to the diminished contractile response to isoproterenol in hypertrophied rat hearts. Pflugers Archiv : European journal of physiology. vol 439. issue 1-2. 2000-03-02. PMID:10650994. |
we tested the hypothesis that changes in phosphorylation of the sarcoplasmic reticulum (sr) protein, phospholamban (pib) and myofibrillar proteins troponin i (tni) and c protein are responsible for the decreased relaxant response to isoproterenol in cardiac hypertrophy and failure induced by ascending aortic banding in rats. |

in isolated perfused heart preparations under maximal isoproterenol stimulation, the capacity for in vitro camp-dependent phosphorylation of pib was significantly increased at the compensatory stage of hypertrophy (126-130%, p<0.001), but decreased with failure (70-76%, p<0.001). |

as a consequence, linear correlation was observed between the maximal increase in ec50 and the maximal rate of relaxation [(-dp/dt)/devp] upon isoproterenol stimulation, declining with progressive hypertrophy to failure. |

isoproterenol (ipr), a beta-adrenergic agonist, induces hypertrophic and hyperplastic enlargement of rat salivary glands and expression of a number of genes including cystatin s. sympathectomy reduces, but does not completely block ipr-induced expression of the cystatin s gene in the submandibular glands of adult female rats, indicating the participation of sympathetic factor(s) in this regulation. |

we found that 1) sepsis reduced contractile function, indicated by a rightward shift in the starling curve (anova with repeated measures, sepsis effect, p < 0.002); 2) sepsis-induced myocardial depression was reversed by isoproterenol treatment (isoproterenol effect, p < 0.0001); 3) sepsis reduced, but did not block, isoproterenol-induced myocardial hypertrophy (isoproterenol effect, p < 0.0001); 4) sepsis did not protect the heart from catecholamine-induced tissue injury; 5) the septic heart was protected against the effects of ischemiareperfusion (decreased postreperfusion resting tension, anova with repeated measures, p < 0.01), an effect attenuated by isoproterenol treatment (p < 0.005); and 6) sepsis reduced the incidence of sustained asystole or ventricular fibrillation after ischemia-reperfusion (p < 0.05), an effect also attenuated by isoproterenol treatment (p < 0.01). |
