ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of combining the injection of beta-sheet breaker H102 with human umbilical cord mesenchymal stem cell (hUCMSC) on APP transgenic mice behavior, P-tau, apoptosis and the expression of relevant enzymes in the brain.</p><p><b>METHODS</b>APP transgenic mice were randomly divided into model group, hUCMSC group, H102 group, H102 with hUCMSC group and a group of C57BL/6J mice with the same age and background was set as normal. After two weeks and four weeks, the ability of spatial reference memory was tested by Morris Water Maze. After four weeks, immunohistochemical stain and Western blot were done to detect the content of Bad, Bax, Bcl-2, Bcl-xl, P-tau, GSK-3beta, PP-2A and PP-1 in mice brain.</p><p><b>RESULTS</b>The ability of memory of hUCMSC in 2 weeks group was slightly improved than that in the model group. hUCMSC in four weeks group, H102 group and H102 with hUCMSC group significantly improved the ability of and memory, and reduced the phosphorylation of tau and brain cell's apoptosis of the Alzheimer disease (AD) mice.</p><p><b>CONCLUSION</b>Beta-sheet breaker H102 together with transplanting hUCMSC is an effective therapeutic strategy for AD.</p>
