pHi dependencies of apical and basolateral cariporide-sensitive Na+-induced acid extrusion in cilium-deficient and -competent cell monolayers. Cariporide-sensitive acid extrusion on the basolateral side was best fit with the line y = −280× + 2,017 for the cilium-competent cell monolayers (♦), and y = −341× + 2,389 for the cilium-deficient cell monolayers (■). Cariporide-sensitive acid extrusion on the apical side of cilium-deficient cell monolayers was best fit with the line y = −97× + 673 (▴).
