4-acetoxyscirpendiol of Paecilomyces tenuipes inhibits Na(+)/D-glucose cotransporter expressed in Xenopus laevis oocytes.
Cordyceps, an entomopathogenic fungus, contains many health-promoting ingredients. Recent reports indicate that the consumption of cordyceps helps reduce blood-sugar content in diabetics. However, the mechanism underlying this reduction in circulatory sugar content is not fully understood. Methanolic extracts were prepared from the fruiting bodies of Paecilomyces tenuipes, and 4-beta acetoxysci...
متن کاملVoltage dependence of H+ buffering mediated by sodium bicarbonate cotransport expressed in Xenopus oocytes.
The electrogenic sodium bicarbonate cotransporter (NBCe1) is expressed in many epithelial cells and, in the brain, in glial cells. Little is known about the physiological significance of the NBCe1 for proton homeostasis and for other acid/base-coupled transporters in these cells. We have measured the voltage-dependent transport activity of an NBC from human kidney, type hkNBCe1, expressed in oo...
متن کاملCFTR fails to inhibit the epithelial sodium channel ENaC expressed in Xenopus laevis oocytes.
The cystic fibrosis transmembrane conductance regulator (CFTR) plays a crucial role in regulating fluid secretion by the airways, intestines, sweat glands and other epithelial tissues. It is well established that the CFTR is a cAMP-activated, nucleotide-dependent anion channel, but additional functions are often attributed to it, including regulation of the epithelial sodium channel (ENaC). The...
متن کاملSpecificity and sensitivity of a human olfactory receptor functionally expressed in human embryonic kidney 293 cells and Xenopus Laevis oocytes.
Here, we provide the first evidence for functional expression of a human olfactory receptor protein (OR17-40) and show that recombinant olfactory receptors can be functionally expressed in heterologous systems. A mixture of 100 different odorants (Henkel 100) elicited a transient increase in intracellular [Ca(2+)] in human embryonic kidney 293 (HEK293) cells stably or transiently transfected wi...
متن کاملAntiporter in Xenopus Laevis Oocytes
The amiloride-sensitive Na + /H + antiporter in defolliculated oocytes of Xenopus laevis was characterized by measurements of H Na + influx and apparent H + efflux. Uptake of ^Na"" was linear over a 90-min incubation period and was inhibited approximately 80% with 5xlO~moll~ amiloride. Amiloride-sensitive sodium uptake was reduced following collagenase treatment or oocyte aging. Ko 5 for amilor...
