... on some members of the Na + /H + exchanger family (NHEs), as well as to clarify its consequences on transepithelial fluid flow in T84 cells. In order to do so, transepithelial fluid flow (J v ) was studied by optic techniques and intracellular pH (pH i ) was measured with a fluorescence method. Results...

.... They generate spontaneous membrane potential oscillations at a frequency of about 1/min. These oscillations are calcium-dependent and due to the periodic activation/inactivation of plasma membrane K + channels. Cells exhibit intracellular pH transients in phase with the membrane potential oscillations due...

... and alterations in [Ca 2+ ]i homeostasis are likely candidates. The present study investigates the effect of elevated extracellular glucose concentrations on [Ca 2+ ] i and intracellular pH (pHi) in cultured rat aortic VSM cells. The VSM cells were coloaded with Fura-2 and SNARF-1 for simultaneous [Ca 2+ ]i...

...A. Alfonso; M.A. Botana; M.R. Vieytes; L.M. Botana In a series of experiments aimed to understand the signaling pathways that regulate intracellular pH (pHi) in rat mast cells, the effect of different intracellular mechanisms on the activity of the Na + /H + exchanger was studied. After promoting...
