    Journal: Biull Eksp Biol Med; 1979 Sep; 88(9):349-52. PubMed ID: 229931.
    Abstract:
    Estradiol is shown to induce histidine decarboxylase and histamine to activate adenylate cyclase in the rat uterus. Cyclic AMP like histamine simulates the effect of estradiol, intensifying RNA synthesis and inducing glycolytic enzymes and uterus inhibition. It was found by autoradiography that 3H-estradiol is accepted by the nuclei of some myometrium cells, 3H-histamine by their cytoplasm and 3H-cAMP is selectively bound by endothelium cells of the uterus capillaries. The estradiol messengers (histamine and cAMP) seem to mediate hormonal effect of some uterus heterofunctional cells forming a kind of multicellular functional system.
