ABSTRACT
<p><b>AIM</b>To investigate the inhibition of amyloid beta-protein 42 (Abeta42) production in M146L cells by gamma-schisandrin.</p><p><b>METHODS</b>M146L cells which can produce considerable Abeta42 in vitro were treated with gamma-schisandrin (1.67, 5.00 and 15.00 microg x mL(-1)), beta-secretase inhibitor (S4562, 100.00 microg x mL(-1)) and gamma-secretase inhibitor (S2188, 13.68 microg x mL(-1)), separately. Cell counting kit-8 (CCK-8) was used to assess cell viability. Enzyme-linked immunosorbent assay (ELISA) was carried out to determine the amount of Abeta42. Western blotting was used to examine C99, an intermediary product of APP cleaved by beta-secretase. beta-Secretase and gamma-secretase activities were assayed by commercial kits.</p><p><b>RESULTS</b>The CCK-8 assay indicated that different concentrations of gamma-schisandrin had no neurotoxicity on the cultured M146L. And the ELISA test showed that the amount of Abeta42 secreted by M146L cells treated with gamma-schisandrin (5.00 and 15.00 microg x mL(-1)) decreased obviously as compared with solvent control. The results of Western blotting test indicated that there was no change of C99 contents and beta-secretase activity in gamma-schisandrin treated cells, while gamma-secretase activity decreased obviously.</p><p><b>CONCLUSION</b>gamma-Schisandrin inhibited production of Abeta42 in M146L cells through inhibiting gamma-secretase.</p>
