This study investigated regulatory volume increase (RVI) in rat pancreatic beta-cells. Volume changes in isolated beta-cells were measured by a video-imaging method. Cell shrinkage was induced by exposure to solutions made hypertonic by the addition of 100 mM mannitol. In HEPES-buffered solutions, beta-cells exhibited an RVI which was almost completely abolished by 10 microM bumetanide. These data indicate that Na+-2Cl--K+ cotransporters make a major contribution to RVI in beta-cells. In HCO3… CONTINUE READING
