ABSTRACT
OBJECTIVE@#To investigate the influence of GPT2(glutamic pyruvate transaminase 2)to biological characteristics of human acute myeloid leukemia cell line HL-60.@*METHODS@#The expression of GPT2 in hematological tumor and AML cell was detected. The lentvirus-mediated of short-hairpin RNA (shRNA) was constricted, and the knock-down efficiency of HL-60 in AML cell after infected by lentvirus-mediated was detected by Western blot and Q-PCR. CCK-8 assay and soft agar colony formation assay were used to detect the effect of GPT2 gene deletion to the cell proliferation potential. Fluorescence activated cell sorting(FACS) was used to analyze the effect of gene deletion to the cell cycle and Caspase 3/7 Activity Assay Kit was used to analyze the effect of GPT2 gene deletion to the cell apoptosis.@*RESULTS@#GPT2 showed mRNA high expression in AML patients. CCK-8, soft agar assay, and Caspase 3/7 Activity Assay Kit results showed that compared with shCtrl group, the cells in shGPT2-1、shGPT2-2、shGPT2-3 group showed the slowing down on proliferation, decreasing on colony ability, and the apoptosis of the cells was increasing significantly. FACS showed that GPT2 gene was related to the cycle of HL-60 cell.@*CONCLUSION@#GPT2 appears to involve the proliferation, cycle distribution and apoptosis of AML cell HL-60. The deletion of GPT gene can lead to the inhibitation of cells proliferation and increase apoptosis.
