Effects of extracellular acidification on intracellular pH (pHi) and ATP-induced calcium mobilization were investigated in rabbit lens epithelial cells. Primary-cultured lens epithelial cells of Japanese white rabbits were used. Intracellular calcium ([Ca2+]i) and pHi were measured by using fluorescent dyes, fura-2 acetoxymethylester (fura-2 AM) and 2',7'-bis (carboxyethyl)-5,6-carboxyfluorescein acetoxymethylester (BCECF AM), respectively. The addition of 10 ?mol/L ATP produced an initial peak followed by a sustained increase in [Ca2+]i in a standard artificial aqueous humor at extracellular pH (pH0) 7.40. The initial peak was abolished by pretreatment with 1 ?mol/L thapsigargin, whereas the sustained increase was attenuated in a Ca2+-free solution or by pretreatment with 100 ?mol/L verapamil. Acidification of the pH0 from 7.40 to 6.80 decreased the pHi from 7.21 to 7.03, and enhanced both the initial peak and sustained increase in [Ca2+]i. These results suggest that acidification of pH0 significantly affects the pHi and modifies the ATP-induced [Ca2+]i transient in rabbit lens epithelial cells. |
