Abstract
- Objective: To investigate the effect of ADAM10 inhibitor GI254023X on the proliferation and apoptosis of acute T-lymphoblastic leukemia Jurkat cells and its mechanisms.<br />Methods: Jurkat cells were treated with different concentrations of GI254023X, the proliferation-inhibition curve was assayed and plotted by CCK-8 method, the cell viability and apoptosis was detected by flow cytometry with Annexin V and 7-AAD staining, the cleavage of Notch1 protein was determined by Western blot, the transcripts of anti-apoptotic genes BCL-2, MCL-1, BCL-xl and Notch1 target gene Hes-1 were detected by real-time PCR.<br />Results: The GI254023X obviously inhibited the proliferation of Jurkat cells in concentration-dependent manner. As compared with the control group, the apoptosis of cells increased along with increment of GI254023X concentration. Compared with control group, the expression of Cleaved Notch1 was down-regulated while the expression of Notch1 was up-regulated in a time-dependent manner after the treatment with GI254023X. The levels of MCL-1 and Hes-1 mRNA transcripts in Jurkat cells were reduced in GI254023X treated group, but did not show obvious effect on the level of BCL-2 and BCL-xl mRNA transcripts.<br />Conclusion: GI254023X can remarkably inhibit proliferation and induce apoptosis of Jurkat cells. The inhibition of Notch1 activation and the down-regulation of apoptosis-related gene MCL-1 may be involved in the process of apoptosis.
