Plasma clearance of intravenously injected aspartate aminotransferase isozymes: Evidence for preferential uptake by sinusoidal liver cells
Yukio Kamimoto, Seikoh Horiuchi, Sumio Tanase, Yoshimasa Morino – 1 May 1985 – Both cytosolic (c‐AAT) and mitochondrial (m‐AAT) isozymes of aspartate aminotransferase (EC 2.6.1.1) appear in serum in some diseases including hepatobiliary dysfunction. The present study aimed at elucidation of the mechanism by which AAT isozymes are cleared from blood. Intravenous injection into rats of m‐AAT and c‐AAT purified from rat liver exhibited a biphasic clearance curve with an overall half‐life of 42 min and 4.7 hr, respectively.
