ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of ADAM10 inhibitor GI254023X on the proliferation and apoptosis of multiple myeloma H929 cell line and its mechanisms.</p><p><b>METHODS</b>H929 cells were treated with different concentrations of GI254023X, the proliferation-inhibitive curve was assayed and plotted by CCK-8 method, the cell viability and apoptosis were detected by flow cytometry with Annexin V/7-AAD double staining. The cleavage of Notch1 protein (cleaved notch1) was determined by Western blot. The transcripts of Notch1 target gene Hes-1 were detected by real-time PCR.</p><p><b>RESULTS</b>The GI254023X inhibited the proliferation of H929 cells in the time- and dose- dependent manners. As compared with the control group, the apoptosis of cells increased along with enhancement of GI254023X concentration; The expression of cleaved Notch1 was down-regulated after the treatment with GI254023X. The levels of Hes-1 mRNA transcripts in H929 cells was reduced in GI254023X treated group.</p><p><b>CONCLUSION</b>GI254023X can remarkably inhibit the proliferation and induce the apoptosis of H929 cells. Its mechanism may be associated with inbihition of Notch1 activation.</p>
