ABSTRACT
Objective To investigate the effect of down-regulation of lysine specific demethylase 1 (LSD1) by shRNA on the apoptosis and cell cycle of human acute myelogenous leukemia cells.Methods The lentiviral vector-mediated LSD1-shRNA was transfected into human acute promyelocytic leukemia HL-60 cells and acute monocytic leukemia SHI-1 cells.The expressions of LSD1 mRNA and protein were examined by real time quantitative PCR and Western blot,respectively.The flow cytometry was applied to detect the apoptosis and cell cycle distribution after AnnexinV-PE/7-AAD and PI dying,respectively.Results The expressions of LSD1 mRNA and protein in HL-60 and SHI-1 LSD1-shRNA group were significantly decreased compared with the blank control group and the negative shRNA group (P < 0.01,respectively).The apoptosis levels of HL-60 and SHI-1 cells were significantly increased after knockdown of LSD1 (P < 0.01).Moreover,the cell cycle distribution in the G0/G1 phases was also significantly increased(P < 0.01).Conclusion LSDI-shRNA promotes cell apoptosis and increases the percentage of cells in the G0/G1 phases of human acute myelogenous leukemia cells.
