... that glucokinase is directly involved in β-cell glucose sensing. This idea is further supported by observing major species differences in islet GLUT2 expression, whereas islet cell glucokinase expression and function are strongly conserved. Studies on pure rat β-cells have also shown that cyclic AMP acts...

...T. Uemura; T. Namiki; A. Kimura; T. Yanagisawa; H. Minaguchi In order to know whether gonadotropin-releasing hormone (GnRH)-like substances play a role as local regulators in the ovary, localization of the GnRH receptor, and the effects of GnRH agonist (GnRHa) on the cyclic AMP system in the rat...

...F. Miot; F. Wilkin; S. Dremier; N. Uyttersprot; F. Lamy; J.E. Dumont; C. Maenhaut The activation of the cyclic AMP cascade in dog and human thyroid cells in primary culture induces the expression of differentiated gene expression, hyperfunction and proliferation. These programs are developed...

... cells, we investigated the intermediary roles of cyclic AMP and intracellular Ca 2+ concentration ([Ca 2+ ] i ). Treatment with 100 ng/ml IGF-II produced a significant increase in the basal accumulation of cyclic AMP in porcine granulosa cells. However, no change of [Ca 2+ ] i by IGF-II was noted. IGF...

... for the programmed expression of genes encoding polypeptide hormones. The structure of one of these DNA-binding proteins, a cyclic AMP-responsive protein (CREB) that binds specific DNA regulatory elements in the somatostatin gene, has been deduced from the sequence of a cloned cDNA. The CREB protein contains a DNA...

...Lucia Fiore; Umberto Scapagnini; Pier Luigi Canonico Dihydroergocryptine and dihydroergocristine, two C-9,10-hydrogenated ergot alkaloids, inhibited in a concentration-dependent manner prolactin release and cyclic AMP accumulation in cultured anterior pituitary cells. The inhibitory effect...

..., but proximal tubular sodium reabsorption, estimated by lissamine green transit time, was unaffected. The antidiuretic effect of prolactin could not be attributed to ADH contamination of the ovine prolactin preparation. Kidney cyclic AMP content was increased significantly 5 min after injection of prolactin...

...Joseph R. Sherwin Cat thyroid slices were studied to investigate their responsiveness to thyrotropin stimulation of cyclic AMP accumulation. Ovine and bovine thyrotropin, in the presence of 2.5 m M aminophylline, induced a dose-dependent increase in the cyclic AMP content of cat thyroid tissue...

...P.E. Waaler; L. Aksnes The 24-hour urinary excretion of cyclic AMP was determined in 102 normal boys aged 1.9-16.9 years and in 136 cryptorchids aged 2.5 – 16.9 years. A marked increase of the normal cyclic AMP excretion was found in pubertal years. There was a positive correlation between urinary...

... administration the enzyme seems concentrated at the apical part of the cells. Two hours after hormonal treatment the stain appears scattered throughout the cytoplasm. The coincidence of enzyme location with the possible cyclic AMP sites of action is stressed. 21 11 2008 © 1974 S. Karger AG, Basel...

... with a total loss of insulin-releasing ability. The 5’-nucleotide tri-phosphate derivatives of these nucleotides were all ineffective. It is suggested that cyclic AMP potentiation of glucose-stimulated insulin release in the mouse is highly specific for this nucleotide. 21 11 2008 Insulin release...

...Gastone G. Nussdorfer; Giuseppina Mazzocchi The effects of cyclic AMP and cyclic GMP on the incorporation of 3 H-uridine into glomerulosal cells of hypophysectomized rats were investigated by high resolution autoradiography. The quantitative analysis of autoradiographs shows that cyclic nucleotides...

...A. Peytremann; E. Engel A comparison of the karyotypes and cyclic AMP (cAMP) values of somatic hybrids between malignant and non-malignant mouse cells maintained either in vitro or eliciting tumors in host animals was performed. The segregation patterns of the cells as evidenced by their karyotypic...

... with Cushing’s syndrome. PRKAR1A is a key component of the cyclic AMP signaling pathway that has been implicated in endocrine tumorigenesis and could, at least partly, function as a tumor suppressor gene. Interestingly, patients with isolated PPNAD and no familial history of CNC can also present a germline de...
