Changes in some marker enzyme activities of liver plasma membranes during regeneration after partial hepatectomy in rats

Y Masuda et al. Biochim Biophys Acta. .

Abstract

Liver plasma membranes were isolated from regenerating rat livers between 20 h and 10 days after partial hepatectomy in order to study the effect of partial hepatectomy on some membrane enzyme activities. Mg2+-ATPase (EC 3.6.1.4) activity, but not (Na+ + K+)-ATPase activity, decreased slightly at 2 days, whereas leucyl beta-naphthylamidase (EC3.4.1.1) and 5'-nucleotidase (EC3.1.3.5) activities increased considerably at 1-2 and 3-5 days, respectively. These changes were not parallel to a sharp increase in mitotic activity of liver cells which occurred at 36 h.
