Cyclic adenosine-3',5'-monophosphate stimulates islet B cell replication in neonatal rat pancreatic monolayer cultures.
A possible role for cyclic adenosine 3',5'-monophosphate (cAMP) in islet B cell replication was examined in neonatal rat pancreatic monolayer cultures. Islet cells deteriorated and insulin release decreased during 12 d of culture in medium with 5.6 mM glucose, whereas the cells survived and insulin release increased during culture in medium with 5.6 mM glucose plus the phosphodiesterase inhibit...
متن کاملRenal Effects of Adenosine 3 ' , 5 ' - Cyclic Monophosphate and Dibutyryl Adenosine 3 , 5 ' - Cyclic Monophosphate
An abstract of this work appeared in 1970 Abstracts, The American Society of Nephrology. Received for publication 27 October 1970 and in revised form 28 January 1971. similar to the effect of renal arterial infusion of isoproterenol. The results suggest that synthesis of cyclic AMP in proximal renal tubule cells in response to stimulation of beta adrenergic or other receptors can mediate a decr...
متن کاملUrinary excretion of cyclic adenosine 3',5'-monophosphate and cyclic guanosine 3',5'-monophosphate in malignancy.
The urinary excretion of cyclic adenosine 3',5'-monophosphate (cAMP), corrected for urinary creatinine, was determined in 177 patients with primary or metastatic tumours and in 149 normal subjects. In 26 patients with malignancy and in 10 control subjects the excretion of cyclic guanosine 3',5'-monophosphate (cGMP) was also evaluated. The urinary cAMP/Cr ratio in human neoplasms of epithelial o...
متن کاملPhosphate transport in rat-liver mitochondria.
Vesicles have been prepared by mild sonication of a purified inner membrane fraction from rat liver mitochondria. Such vesicles demonstrate an energy-dependent net concentrative uptake of inorganic phosphate in the absence of added Na+, Ca’+, or ionophores. Phosphate uptake can be supported by a variety of substrates including /?-hydroxybutyrate, succinate, and ascorbate + tetramethylphenylened...
متن کاملEffect of Adenosine 3'-5'-cyclic Monophosphate on Cell Proliferation
Secondary cultures of human diploid fibroblasts, which demonstrate density-dependent inhibition of cell growth, were used to study the effect of adenosine 3'-5'-cyclic monophosphate (cAMP) on cell proliferation. DNA synthesis in nonconfluent cultures and in contact-inhibited cultures stimulated to grow by refeeding with fresh medium was found to be inhibited by exogenous cAMP. The properties of...
