Acute Activation of the Renal Betaine/GABA Transporter in Response to a Decrease in Extracellular Calcium
Figure 6
(a) Superperfusion of MDCK monolayers with low Ca2+ medium produced a rapid decrease in intracellular calcium concentration, based on fura-2 imaging, which was reversed completely by switching back to normal calcium medium. (b) Comparison of the peak values showed the fall in intracellular calcium was statistically significant. *. Data are mean SD from 22 cells.
