Effects of adenosine 3',5'-monophosphate and adenosine 5'-monophosphate on glycogen degradation and synthesis in Dictyostelium discoideum.
Data are presented demonstrating that the presence in vivo of adenosine 3',5'-monophosphate (3',5'-AMP) causes a rapid depletion of glycogen storage material in the cellular slime mold. The effect of adenosine 5'-monophosphate (5'-AMP) is twofold, stimulating both glycogen degradation and synthesis. In pseudoplasmodia, cell-free extracts appear to contain at least two species of glycogen phosph...
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...

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 کاملIdentification of adenosine-3',5'-monophosphate as the bacterial attractant for myxamoebae of Dictyostelium discoideum.
Adenosine-3',5'-cyclic monophosphate was shown to be the compound found in Escherichia coli responsible for the attraction of the amoebae of the cellular slime mold Dictyostelium discoideum. A number of other nucleotides were tested and the following were active: tubercidin-3',5'-cyclic monophosphate, N(6)-2'-O-dibutyryl-adenosine-3',5'-cyclic monophosphate, 5'-methylene adenosine-3',5'-cyclic ...
متن کاملChemoattraction and chemotaxis in Dictyostelium discoideum: myxamoeba cannot read spatial gradients of cyclic adenosine monophosphate
Myxamoebae of the morphogenetic cellular slime mold Dictyostelium discoideum are thought to be able to accurately read and respond to directional information in spatial gradients of cyclic AMP. We examined the spatial and temporal mechanisms proposed for chemotaxis by comparing the behavior of spreading or evenly distributed cell populations after exposure to well-defined spatial gradients. The...
