Ultracytochemical observation of the intracellular localization of H+-adenosine triphosphatase / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To observe the ultracytochemical localization of H(+)-adenosine triphosphatase (H(+)-ATPase) in the cell organelles.</p><p><b>METHODS</b>The localization of H(+)-ATPase in the cell organelles was observed in the hepatocytes and renal cells of Wistar rats using routine ultracytochemical methods.</p><p><b>RESULTS</b>H(+)-ATPase activities were observed on the lysosomal membrane and nuclear envelope of the hepatocytes and proximal tubule epithelial cells of the nephron in Wistar rats.</p><p><b>CONCLUSION</b>This finding supports the hypothesis that H(+)-ATPase (V-ATPase) is present on the plasma membrane and in the endomembrane system.</p>
