Excitation, adaption, and deadaptation of the cAMP-mediated cGMP Response in dictyostelium discoideum
Extracellular cAMP induces chemotaxis and cell aggregation in dictyostelium discoideum cells. cAMP added to a cell suspension is rapidly hydrolyzed (half-life of 10 s) and induces a rapid increase of intracellular cGMP levels, which reach a peak at 10 s and recover prestimulated levels at about 30 s. This recovery is not due to removal of the stimulus because the nonhydrolyzable analogue adenos...
متن کاملAngiopoietin-2 and rat brain capillary remodeling during adaptation and deadaptation to prolonged mild hypoxia.
Angiogenesis is a crucial component of rat brain adaptation to prolonged hypoxia, but it is not known whether this structural change is permanent or reversed on return to normoxia. Also, the intrinsic mechanisms controlling brain microvascular plasticity in response to oxygen availability remains unclear. Our results indicate that capillary density in the rat cerebral cortex increased by 60% af...

متن کاملEnzymatic and chemo-enzymatic synthesis of carbohydrates
Carbohydrate-mediated biochemical recognition processes are potential targets for drug development. The synthesis of complex carbohydrates and related structures, however, has been a difficult task, especially from practical point of view. New solutionand solidphase methods based on enzymatic and a combined enzymatic and chemical procedure have recently been developed for the practical synthesi...
متن کاملEnzymatic Assays
Rat liver microsomal glycoproteins were purified by affinity chromatography on concanavalin A Sepharose columns from membrane and content fractions, separated from rough microsomes (RM) treated with low concentrations of deoxycholate (DOC). All periodic acid-Schiff (PAS)-positive glycoproteins of RM showed affinity for concanavalin A Sepharose; even after sodium dodecyl sulfate (SDS) acrylamide...
