Renal 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 کاملDifferential binding of cyclic adenosine 3' ,5'-monophosphate to the cyclic adenosine 3' ,5'-monophosphate receptor protein in Escherichia coli.
Binding of cyclic adenosine 3' ,5'-monophosphate (cAMP) by the cAMP receptor protein in crude cell-free extracts of Escherichia coli was characterized. When cell were grown in glucose, binding was inhibited 50% relative to extracts from cells grown with succinate as carbon source . This inhibition could be relieved by dialysis.
متن کاملMode of action of parathyroid hormone and cyclic adenosine 3',5'-monophosphate on renal tubular phosphate reabsorption in the dog.
To evaluate the effects of parathyroid hormone and cyclic adenosine monophosphate on proximal tubular sodium and phosphate reabsorption, micropuncture studies were performed on dogs that received a highly purified preparation of parathyroid hormone (PTH), dibutyryl cyclic 3',5'-adenosine monophosphate (cyclic AMP), 5'-AMP, and saline. PTH resulted in a 30-40% inhibition of sodium and phosphate ...
متن کاملEffects of adenosine 5'-monophosphate and adenosine 3',5'-cyclic monophosphate on l cells.
The adenine nucleotides, 5'-AMP and 3',5'-cyclic AMP block L cells in the S-phase of the cell cycle. The intracellular level of cyclic AMP is reduced after incubation of cells with 5'-AMP, and rates of uridine transport are increased after incubation with either 5'-AMP or cyclic AMP. On the contrary, cyclic AMP levels are increased and uridine transport decreased in cells treated with an inhibi...
