ABSTRACT
<p><b>OBJECTIVE</b>To investigate the effect of monoamine oxidase inhibitor phenelzine on in vitro growth and proliferation of mantle cell lymphoma Jeko-1 cells and its possible mechanism.</p><p><b>METHODS</b>MTT assay was used to observe the cell proliferation and to draw a growth curve. The cell apoptosis was measured by flow cytometry. The expressions of apoptosis-related protein and Wnt signal pathway as well as the level of acetylation of histone were analyzed by Western blot.</p><p><b>RESULTS</b>Phenelzine inhibited proliferation and promoted apoptosis of Jeko-1 cells in a dose-dependent way by increasing the expression of apoptosis related protein BAX, Caspase-3 and p21, while decreasing anti-apoptotic protein BCL-2. In addition, phenelzine could upregulate histone H3K4mel, H3K4me2 and histone acetylated H3, without affecting hitone H3K4me3. Moreover, phosphorylation of GSF-3β, β-catenin, c-myc and cyclinD1 decreased after exposure to phenelzine for 24 hours.</p><p><b>CONCLUSION</b>Phenelzine can inhibit Jeko-1 cell proliferation and induce apoptosis by regulating methylation and acetylation of histone and suppressing Wnt/β-catenin signal pathway, suggesting its therapeutic benefit for mantle cell lymophma.</p>
