ABSTRACT
<p><b>OBJECTIVE</b>To investigate the biological effects of sertraline, one of psychotropic drugs, on actue myeloid leukemia cell line Kasumi-1.</p><p><b>METHODS</b>Cells were treated by different concentrations of sertraline for different times. The effects of sertraline were evaluated by cell growth, cell morphology, cell cycle distribution and markers of cell apoptosis, respectively. Western blot was used to detect the expression change of related proteins.</p><p><b>RESULTS</b>Sertraline could inhibit cell proliferation and induce apoptosis. After treatment with 15 µmol/L and 20 µmol/L sertraline for 24 h, the inhibitory rate of Kasumi-1 cell proliferation was (19.00 ± 7.37)% and (47.90 ± 11.19)%, respectively. Meanwhile, compared with the control group, the percentage of Annexin V positive cells in Kasumi-1 cells treated with sertraline for 24 h raised obviously from (9.71 ± 2.12)% to (20.54 ± 2.52)% and (45.37 ± 7.88)% (P < 0.01), respectively. The cells were arrested in G0/G1 and G2/M phase. In addition, it was found that sertraline could also down-regulate the level of translationally controlled tumor protein (TCTP) in Kasumi-1 cells.</p><p><b>CONCLUSION</b>Sertraline can significantly induce the apoptosis of Kasumi-1 cells, that probably is associated with the down-regulation of TCTP protein expression.</p>
