Cl- and regulation of pH by MDCK-C11 cells.
The interaction between H(+) extrusion via H(+)-ATPase and Cl(-) conductance was studied in the C11 clone of MDCK cells, akin to the intercalated cells of the collecting duct. Cell pH (pHi) was measured by fluorescence microscopy using the fluorescein-derived probe BCECF-AM. Control recovery rate measured after a 20 mM NH(4)Cl acid pulse was 0.136 +/- 0.008 pH units/min (dpHi/dt) in Na(+) Ringe...
متن کاملPurinergic-induced signaling in C11-MDCK cells inhibits the secretory Na-K-Cl cotransporter.
Purinergic inhibition of Na-K-Cl cotransport has been noted in various renal epithelial cells derived from the collecting tubule, including Madin-Darby canine kidney (MDCK) cells. In recent studies, we have observed purinergic inhibition of Na-K-Cl cotransport in C11-MDCK subclones (alpha-intercalated-like cells). Interestingly, Na-K-Cl cotransport activity was also detected in C7-MDCK subclone...

متن کاملAmmonium transport and pH regulation by K(+)-Cl(-) cotransporters.
The Na(+)-K(+)-Cl(-) cotransporters (NKCCs), which belong to the cation-Cl(-) cotransporter (CCC) family, are able to translocate NH4(+) across cell membranes. In this study, we have used the oocyte expression system to determine whether the K(+)-Cl(-) cotransporters (KCCs) can also transport NH4(+) and whether they play a role in pH regulation. Our results demonstrate that all of the CCCs exam...
متن کاملRegulation of Na+-independent Cl-/HCO3- exchangers by pH.
Among human bicarbonate transporters, two major gene families encode Na-independent Cl(-)/HCO(3)(-) exchangers: the SLC4 anion exchanger (AE) family, and the SLC26 "sulfate permease" anion transporter family. The SLC4 AE family contains at least three genes, and comprises a subfamily within the larger and phylogenetically more ancient bicarbonate transporter superfamily that includes the Na bic...
