To investigate the influence of GPT2（glutamic pyruvate transaminase 2）to biological characteristics of human acute myeloid leukemia cell line HL-60.

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.

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.

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.

To establish a method for rapid detection and typing of NPM1 mutations in acute myeloid leukemia (AML) by fluorescence melting curve analysis technology.

A pair of primers and a fluorescent single-stranded probe (molecule beacon) were designed for the mutant genes mutA, mutB, mutD in exon 12 of nucleopsin (NPM1) and wild type. With a real-time qPCR, the A, B, and D gene mutations of NPM1 were detected and typed by different-melting curve peak value of the probe through RT-PCR.

This method could detected the mutations of A, B, and D in NPM1 effectively with a sensitivity of 1%. Furthermore, 62 AML clinical samples were evaluated by the method. In the results, the detection rate and typing of NPM1 mutations were consistent with the sequencing results of clinical samples.

There are three features in the method of fluorescence melting curve analysis stable PCR system, easy to operate, and the easily distinguishable results. this website The method might meet the demand for rapid typing of NPM1 gene mutation in early diagnosis or concomitant diagnosis of AML.

To investigate the effect of etoposide (ETO) on elimination of chronic myeloid leukemia (CML) stem cells by imatinib mesylate(IM) in vivo.

SCL-tTA/BCR-ABL mice were used as CML animal model. Flow cytometry was used to assess the effect of ETO alone or in combination with IM on the number of leukemia stem cell （LSC） in bone marrow and spleen, and peripheral blood neutrophils in CML mice and normal control FVB mice.

The results showed that in CML mice, the number and proportion of LSC in bone marrow and the proportion of neutrophils in peripheral blood decreased significantly after ETO and IM combined treatment, and the degree of decrease was more significant than that of both alone. While in wild type FVB mice, the combination of ETO and IM showed no significant effect on the number and proportion of LSK cells in bone marrow and the proportion of neutrophils in spleen.

ETO can selectively enhance elimination of CML LSC by IM in vivo.

To investigate the effects of recombinant human thrombopoietin (rhTPO) to proliferation and apoptosis of acute myeloid leukemia (AML) cell lines.

After the treatment of different concentrations of rhTPO (0, 50, 100 ng/ml) for different time (24,48,72 h)，the cell proliferation rates of the AML cell lines (Kasumi-1, Skno-1, HEL, HL-60, THP-1) were determined by CCK-8 method. Apoptosis rate of each cell line cocultured with rhTPO was detected by Annexin V/PI method. The relative expression of TPO receptor c-MPL (myeloproliferative clonal antibody) mRNA in AML cell lines was detected by Q-PCR. The expression of c-MPL protein in each cell line was detected by Western blot. The expression of c-MPL antigen in HL-60 cells treated by different concentrations of rhTPO was detected by Flow cytometry.

RhTPO showed no promotion to the proliferation of Kasumi-1, Skno-1, HEL, HL-60, THP-1 cell lines，however，it showed inhibitory effect to cell proliferation (72 h 0 ng/ml vs 100 ng/ml, P= 0.029) and pro-apoptotic (48 h related to c-MPL gene expression or protein expression.
The present study was to evaluate the anti-tumor effects of acidic RNA protein complex (FA-2-b-β) extracted from the wild edible Qinba mushroom in inducing of apoptosis and immunoregulation of tumor cell.

Cell proliferation inducing rate of FA-2-b-β to K562 cell was measured using CCK-8. Apoptosis rate was detected by using flow cytometry. Chronic myeloid leukemia model was developed by tail vein injection/subcutaneous inoculation of K562 cells in NCG mice. The tumor burden of mice was observed. The general condition of the mice was monitored twice daily. The peripherivcal full blood counts of mice was tested daily. RT-qPCR and Western blot was FA-2-b-β performed to determine involvement of apoptotic-related gene and protenin, Immunofluorescence and immunohistochemistry was used to detected the expression of CD3, CD4 and CD8.

The proliferation and apoptosis of K562 cell could be inhibitied and induced by FA-2-b-β, there was 100% successful in the tumor formation in vivo, after treated by drug for 21 days there were significantly increased peripheral leucocytes, but decreased hemoglobin of mice treated by FA-2-b-β as compared with those in control group. The CD3, CD4 and CD8 showed positive in mice, and the propotation was imbalance, but it showed reserved after treated by FA-2-b-β.

FA-2-b-β is strong anti-leukemia effect in vitro and in vivo, suggesting the traditional Chinese medicine maybe contribute to the anti-cancer and immunoregulation research.
