  • Title: Inositol phosphate production following alpha 1-adrenergic, muscarinic or electrical stimulation in isolated rat heart.
    Author: Poggioli J, Sulpice JC, Vassort G.
    Journal: FEBS Lett; 1986 Oct 06; 206(2):292-8. PubMed ID: 3019774.
    Abstract:
    A possible participation of polyphosphoinositide metabolism in the excitation-contraction coupling in heart was investigated. Isolated rat ventricles prelabelled with myo-[2-3H]inositol were stimulated by conditions that increase mechanical activity. Both noradrenaline and carbachol increased the basal level of IP3, IP2 and IP by the activation of alpha 1-adrenergic and muscarinic receptors, respectively. Electrical stimulation accelerated inositol lipid degradation by phospholipase C thus enhancing the IP3 level as compared to quiescent ventricles. It is proposed that IP3 may be involved in excitation-contraction coupling in cardiac tissue.
