Adenosine triphosphate content of preimplantation mouse embryos.
The utilization of energy substrates by preimplantation mouse embryos undergoes several changes during development in vitro (Brinster, 1965a, b) but very little is known about the level of high-energy containing compounds, such as ATP at these stages. In the present study, the content ofATP in freshly collected preimplantation mouse embryos has been measured. For each estimation, fifty to 150 e...
متن کاملCytochalasin B and the Adenosine Triphosphate Content of Treated Fibroblasts
INTRODUCTION the addition of the drug . Concentrations of about 3 μg/ml were required to observe altered cell morphology. The possibility was considered that depolymerization of microfilaments-with a resulting change in cell shape and function--resulted from a rapid depletion of intracellular energy levels brought about by the inhibition of sugar transport . The effects of cytochalasin B and io...
متن کاملAdenosine triphosphate inhibition in myosin adenosine triphosphate systems.
Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the nucleoside triphosphatase activity of myosin A could be qual...
متن کاملAdenosine Triphosphate-dependent Taurocholate
Transport systems involved in uptake and biliary secretion of bile salts have been extensively studied in rat liver; however, little is known about these systems in the human liver. In this study, we investigated taurocholate (TC) transport in canalicular and basolateral plasma membrane vesicles isolated from 15 human livers (donor age 6-64 yr). ATP stimulated the uptake ofTC into both canalicu...
متن کاملIntracellular compartmentalization of adenosine triphosphate.
The intracellular distribution and diffusivity of adenosine triphosphate (ATP) was studied by cryomicrodissection of individual Rana pipiens oocytes. We measured ATP concentrations in the nucleus, in animal and vegetal hemisphere cytoplasm, and in an intracellular reference phase (iRP, a microinjected gelatin "organelle") which samples diffusive ATP. Regional concentrations were not equal: nucl...
