  ABSTRACT: To analyze the cytogenetic characteristics of different age subgroups in patients with acute myeloid leukemia (AML), and to explore the relationship between age and cytogenetics. Between January 2004 and December 2011, Bone marrow (BM) samples from 640 patients with de novo AML were analyzed retrospectively. The analyses were performed according to standard culturing and banding techniques, and clonal abnormalities were defined and described according to the International System for Human Cytogenetic Nomenclature (ISCN 2009). The cytogenetic subtypes were performed as normal, balanced, and unbalanced karyotypes. In the last group, the age distribution of complex and monosomal karyotypes were further analyzed. The patients were divided into 8 age groups: 0 - 9, 10 - 19, 20 - 29, 30 - 39, 40 - 49, 50 - 59, 60 - 69, and ≥ 70 year old groups. The distribution of normal, balanced, and unbalanced karyotypes showed age specific characteristics. The incidence of normal karyotype increased from 6.67% (0 ∼ 9 year old) to 58.33% (≥ 70) (χ(2) = 20.68, P = 0.001) and balanced karyotype decreased from 73.33% (0 ∼ 9) to 11.11% (≥ 70) (χ(2) = 48.22, P < 0.01). The frequency of unbalanced karyotypes increased from 20.0% (0 ∼ 9) to 30.56% (≥ 70) (χ(2) = 18.963, P = 0.008). The frequency of complex karyotype was 6.67% in 0 - 9 year old group, followed by 0% in 10 - 19 and 20 - 29 year old group, and from 1.72% to 11.11% from 30 - 39 to ≥ 70 year old group (χ(2) = 8.341, P = 0.08). Monosomal karyotype was only detected in patients in 30 year old or older groups. Although an increased tendency was observed with ages, there was no significant difference (χ(2) = 4.778, P = 0.311). The different age profiles of the cytogenetic subtypes may indicate the different mechanisms of the pathogenesis of AML, which may also offer beneficial information for etiological research of AML.

  ABSTRACT: To find a kind of quick and effective haemostasis to decrease the mortality of severe bleeding. 18 severe bleeding patients with different cause received recombinant activated factor VIIa (rFVIIa) were analyzed retrospectively. Of total 18 cases with severe bleeding, 13 cases cured, 3 cases were effective, 2 cases ineffective. The total clinical effective rate is 88.89%. After using rFVIIa, the PT, APTT and fibrinogen level of 6 DIC patients returned to normal within 12 hours; 13 patients whose the amount of bleeding can be evaluated stopped bleeding quickly. The fastest onset time was 10 min. rFVIIa can stanch severe bleeding for a variety of reasons rapidly and effectively, including coagulopathy, thrombocytopenia, and obstetric hemorrhage. Application of rFVIIa may decrease mortality, when conventional treatment is not valid.

• Article: Knockdown of a proliferation-inducing ligand (PRIL) suppresses the proliferation of gastric cancer cells.

  [show abstract] [hide abstract]
  ABSTRACT: PRIL (proliferation-inducing ligand) is a newly identified member of the tumor necrosis factor (TNF) family and modulates death ligand-induced apoptosis. Here, we investigated the effect of PRIL on cellular characteristics relating to tumor progression in human gastric cancer. Recombinant lentivirus containing APRIL siRNA was constructed and then infected MGC803 and SGC7901 gastric cancer cells. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] colony formation and cell cycle analysis were used to study the effect of APRIL knockdown on gastric cancer cell proliferation. PRIL expression in lentivirus infected cells was significantly reduced as evidenced by quantitative real-time PCR. Cell viability and colony formation of MGC803 and SGC7901 cells were significantly hampered in PRIL knock-down cells. Moreover, the cell cycle was arrested at G2/M phase, elucidating the mechanism underlying the inhibitory effect of siRNA on cell proliferation. Our study indicated that PRIL functions in promoting cell growth, and lentivirus-mediated PRIL gene knockdown might be a promising strategy in the treatment of gastric cancer.

• Article: Silencing of the COPS3 gene by siRNA reduces proliferation of lung cancer cells most likely via induction of cell cycle arrest and apoptosis.

  ABSTRACT: The COPS3 gene has stimulating effect on cell proliferation and progression of osteosarcomas and related cells. However, the features of COPS3 and its potential application as a therapeutic target in other cancers has not yet been studied. In this study, therefore, the effect of COPS3 silencing via COPS3 siRNA on lung cancer cell proliferation was examined. Expression levels of COPS3 gene in COPS3 siRNA infected cells and control siRNA infected cells were compared with real time PCR and Western blot analysis. Cell proliferation levels were comprehensively analyzed by MTT, BrdU incorporationy, and colony formation assays. For mechanistic assessment the effects of COPS3 silencing on cell cycle and apoptosis were analyzed using flow cytometry. Results showed that successful silencing of the COPS3 gene at both translational and transcriptional levels significantly reduced the proliferation and colony formation by lung cancer cells (p<0.01). Flow cytometry showed cell cycle arrest in the G0/G1 phase after COPS3 silencing, and more importantly, apoptosis was induced as a result of COPS3 knockdown, which negatively affected cell survival. Therefore, these results provide another piece of important evidence that the COPS3 gene expressed in lung cancer cells may play a critical role in stimulating proliferation. Down-regulation of COPS3 could significantly inhibit lung cancer cell growth, which was most likely mediated via induction of cell cycle arrest in G0/G1 phase and apoptosis.

  ABSTRACT: The activation of Fli-1, an Ets transcription factor, is the critical genetic event in Friend murine leukemia virus (F-MuLV)-induced erythroleukemia. Fli-1 overexpression leads to erythropoietin-dependent erythroblast proliferation, enhanced survival, and inhibition of terminal differentiation, through activation of the Ras pathway. However, the mechanism by which Fli-1 activates this signal transduction pathway has yet to be identified. Down-regulation of the Src homology 2 (SH2) domain-containing inositol-5-phosphatase-1 (SHIP-1) is associated with erythropoietin-stimulated erythroleukemic cells and correlates with increased proliferation of transformed cells. In this study, we have shown that F-MuLV-infected SHIP-1 knockout mice display accelerated erythroleukemia progression. In addition, RNA interference (RNAi)-mediated suppression of SHIP-1 in erythroleukemia cells activates the phosphatidylinositol 3-kinase (PI 3-K) and extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathways, blocks erythroid differentiation, accelerates erythropoietin-induced proliferation, and leads to PI 3-K-dependent Fli-1 up-regulation. Chromatin immunoprecipitation and luciferase assays confirmed that Fli-1 binds directly to an Ets DNA binding site within the SHIP-1 promoter and suppresses SHIP-1 transcription. These data provide evidence to suggest that SHIP-1 is a direct Fli-1 target, SHIP-1 and Fli-1 regulate each other in a negative feedback loop, and the suppression of SHIP-1 by Fli-1 plays an important role in the transformation of erythroid progenitors by F-MuLV.

  ABSTRACT: This study was aimed to construct the shRNA eukaryotic expression vectors of M2-pyruvate kinase gene (pkm2) and to investigate the effects of pkm2 gene interference on the drug resistance of acute promyelocytic leukemia (APL) cells in vitro. Three specific shRNAs of pkm2 gene were designed and cloned into PBSU6 vector containing a U6 promotor. The constructed plasmids were identified and proved by the restriction sequence analysis. Then the effect of pkm2-shRNA on the protein expression of endogenous PKM2 was detected in NB4R2 cells, a drug resistant cell line of APL by Western blot. The alteration of NB4R2 cell differentiation with the interference of pkm2 gene was also validated by nitroblue tetrazolium (NBT) reduction test. The results showed that three specific shRNA eukaryotic expression vectors targeting pkm2 were successfully constructed. The efficiency of pkm2 gene silence was proved at protein level. The interference of pkm2 gene could significantly enhance the cell differentiation in the drug resistant NB4R2 cell line. It is concluded that the DNA vector containing pkm2 targeting shRNA remarkably promotes the differentiation of NB4R2 cells, showing the prospects of developing the gene target drug.

  ABSTRACT: MicroRNAs (miRNAs) are a newly discovered class of posttranscriptional regulatory noncoding small RNAs. Recent evidence has shown that miRNA misexpression correlates with progression of various human cancers. Friend erythroleukemia has been used as an excellent system for the identification and characterization of oncogenes and tumor suppressor genes involved in neoplastic transformation. Using this model, we have isolated a novel integration site designated Fli-3, from a Friend murine leukemia virus (F-MuLV)-induced erythroleukemia. The Fli-3 transcription unit is a murine homologue of the human gene C13orf25 that includes a region encoding the mir-17-92 miRNA cluster. C13orf25 is the target gene of 13q31 chromosomal amplification in human B-cell lymphomas and other malignancies. The erythroleukemias that have acquired either insertional activation or amplification of Fli-3 express higher levels of the primary or mature miRNAs derived from mir-17-92. The ectopic expression of Fli-3 in an erythroblastic cell line switches erythropoietin (Epo)-induced differentiation to Epo-induced proliferation through activation of the Ras and PI3K pathways. Such a response is associated with alteration in the expression of several regulatory factors, such as Spi-1 and p27 (Kip1). These findings highlight the potential of the Fli-3 encoding mir-17-92 in the development of erythroleukemia and its important role in hematopoiesis.

  ABSTRACT: To explore the molecular mechanisms of apoptotic NB4 cells induced by the histone deacetylase inhibitor, sodium butyrate(SB). SB was exposed to NB4 cells at a final concentration of 1.0 mmol/L. The untreated and treated cells were analysed with FACS and 2-dimensional electrophoresis (2-DE) at 0, 12, 24, 48 and 72 h. The changed protein spots were identified with MALDI-TOF-MS and ESI-TOF-MS/MS. SB induced apoptosis of NB4 cells. Twenty-one changed proteins involving apoptotic signal transduction, immunological regulation, transcriptional control, cellular metabolism, molecular transport and so on were identified. Thirteen of them had been reported to be related to apoptosis. SB can induce apoptosis and many functional protein changes in tumor cells. These results pave the way to further explore the anti-tumor mechanism of SB.

  ABSTRACT: This study was aimed to analyze the different proteomes between human acute leukemia (AL) cells and normal white blood cells by proteomic technology in order to lay the basis for diagnosing AL and understanding the mechanism of leukemogenesis. The proteins from AL cells of 40 AL patients identified by FAB classification and proteins from normal lymphocytes and granulocytes of 20 normal volunteers were separated by two-dimensional electrophoresis (2-DE), and the differentially expressed proteins between the two groups were identified by both matrix assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) and electronspray ionization (ESI)-MS/MS. The results showed that among the differentially expressed proteins between AL cells and normal lymphocytes and granulocytes, some proteins involved in the process of malignant transformation (such as Op18, NM23-H1), cell proliferation (such as PCNA) and apoptosis inhibition (such as tumor necrosis factor inhibitor protein) were found to be up regulated in AL cells. However, some proteins involved in differentiation and physiological functions of normal cells were down regulated in AL cells. It is concluded that there are many events involved in the process of leukemogenesis, expression of some proteins relating to the malignant transformation, cell proliferation and apoptosis inhibition are up-regulated in AL cells. The proteome analysis may provide a new approach to explaining the molecular mechanism underlying the pathogenesis of AL.

  ABSTRACT: The identification of panels of tumor antigens that elicit an antibody response may have utility in cancer screening, diagnosis, and establishing prognosis. Until now, autoimmunity in cancer has been mainly revealed in solid tumors. The aim of this study was to apply the proteomic approach to the identification of proteins that commonly elicit a humoral response in acute leukemia (AL). Sera from 21 newly diagnosed patients with AL, 20 patients with solid tumors, and 22 noncancer controls were analyzed for antibody-based reactivity against AL proteins resolved by two-dimensional electrophoresis. As a result, autoantibody against a protein identified by mass spectrometry as Rho GDP dissociation inhibitor 2 was detected in sera from 15 of 21 patients with AL (71%). By contrast, such antibody was detected in sera from one of 20 patients with solid tumors (5%) and one of 22 noncancer controls (4.5%). Five other protein autoantibodies were also found in AL patients with a high frequency and constituted the major target antigens of the AL autoimmune response. The findings of autoantibodies against Rho GDP dissociation inhibitor 2 and other proteins in sera of patients with AL suggest that the proteomic approach we have implemented may have utility for the development of a serum-based assay for AL screening and diagnosis.

  ABSTRACT: To observe the therapeutic efficacy and side effects of arsenic trioxide (As2O3)combined with low-dose all-trans retinoic acid (ATRA) on remission induction in newly-diagnosed and relapsed patients with acute promyeloeytic leukemia (APL). 224 patients of APL, 156 newly diagnosed patients, aged 34 (13 approximately 62), with a male/female ratio of 1.56, and 28 relapsed patients, aged, aged 34 (12 approximately 63), with a male/female ratio of 1.89, underwent As2O3 + ATRA therapy. The therapeutic effects was compared with that of As2O3 alone treatment on 40 newly diagnosed patients and 25 relapsed patients and that of ATRA alone treatment on 36 newly diagnosed patients and 15 relapsed patients. The treatment protocol for the combination group was as following: As2O3 was administered intravenously at a dose of 10 mg/day and ATRA was given orally three times per day at a dose of 10 mg. The complete remission (CR) rate, period to CR, incidence of early death and side effects were observed in the three groups. In the newly-diagnosed patients, there was no significant difference in CR rate among the three groups (92.5% for the As2O3/LD-ATRA group, 83.8% for the ATRA group, and 90% for the As2O3 group respectively). In comparison with As2O3 alone, administration of LD-ATRA to the patients in the As2O3/LD-ATRA group significantly shortened the period to CR (the medium time to CR was 28 days for the As2O3/LD-ATRA group and 39 days for the As2O3 group respectively). As compared to ATRA alone, treatment with As2O3 with low-dose ATRA showed a significantly lower incidence of early death (2.5% for the As2O3/LD-ATRA group and 13.9% for the ATRA group respectively). In the relapsed patients, the CR rate was significantly higher in the group treated with As2O3/LD-ATRA (71.4% for the As2O3/LD-ATRA group, 32.0% for the ATRA group, and 43.0% for the As2O3 group respectively). The combined use of LD-ATRA with As2O3 did not further enhance toxic side effects as compared to As2O3 alone or ATRA alone. As2O3/LD-ATRA regimen is superior to either regimen given alone to patients with APL. It is an efficient therapeutic approach to APL patients using a combination of As2O3 with low-dose ATRA.

  ABSTRACT: Two-dimensional electrophoresis (2-DE) was used to profile the proteins of leukemic cells from 61 cases of akute leukemia (AL) characterized by the French-American-British (FAB) classification. The differentially expressed protein spots were identified by matrix assisted laser desorption/ionization-time of flight-mass spectrometry (MALDI-TOF-MS) and electrospray ionization-tandem MS (ESI-MS/MS). The distinct protein profiles (DPPs) of AL FAB subtypes were explored successfully, including acute myeloid leukemia (AML), its subtypes (M2, M3, and M5), and acute lymphoid leukemia (ALL), which were homogeneous within different samples of the same subgroup but clearly differed from all other subgroups. We also found a group of proteins differentially expressed between AL cells and normal white blood cells. Among the DPPs of AL subtypes, some proteins have been reported, but most of them were first reported here to mark AML differentiation and to discriminate AML from ALL. These data show that 2-DE protein profiling could be used as an analytical tool for facilitating molecular definition of human AL classification and understanding the mechanism of leukemogensis, and the extension of the present analysis to the currently less well-defined AL will identify additional subgroups and may promote the identification of new targets for specific treatment approaches.

  ABSTRACT: French-American-British (FAB) classification of acute leukemia with genetic heterogeneity is important for treatment and prognosis. However, the distinct protein profiles that contribute to the subtypes and facilitate molecular definition of acute leukemia classification are still unclear. The proteins of leukemic cells from 61 cases of acute leukemia characterized by FAB classification were separated by two-dimensional electrophoresis, and the differentially expressed protein spots were identified by both matrix-assisted laser desorption/ionization-time-of-flight-mass spectrometry (MALDI-TOF-MS) and tandem electrospray ionization MS (ESI-MS/MS). The distinct protein profiles of acute leukemia FAB types or subtypes were successfully explored, including acute myeloid leukemia (AML), its subtypes (M2, M3, and M5) and acute lymphoid leukemia (ALL), which were homogeneous within substantial samples of the respective subgroups but clearly differed from all other subgroups. We found a group of proteins that were highly expressed in M2 and M3, rather than other subtypes. Among them, myeloid-related proteins 8 and 14 were first reported to mark AML differentiation and to differentiate AML from ALL. Heat shock 27 kDa protein 1 and other proteins that are highly expressed in ALL may play important roles in clinically distinguishing AML from ALL. Another set of proteins up-regulated was restricted to granulocytic lineage leukemia. High-level expression of NM23-H1 was found in all but the M3a subtype, with favorable prognosis. These data have implications in delineating the pathways of aberrant gene expression underlying the pathogenesis of acute leukemia and could facilitate molecular definition of FAB classification. The extension of the present analysis to currently less well-defined acute leukemias will identify additional subgroups.

  ABSTRACT: Acute myelogenous leukemia (AML) cells are organized in a hierarchical fashion, with only the most primitive rare population (leukemia stem cell, LSC) of AML cells capable of maintaining the leukemic clone. A broad range of studies has indicated that AML results from mutations at the level of the stem cells of AML cells. The changes of cellular and molecular features in these malignant stem cells determine the features of leukemic clone and give rise to different subtypes of AML. LSCs share some similar characteristics with normal hematopoietic stem cells (HSC) including the ability to self-renew, and also have the potential of limited differentiation. LSCs, also have some features that are not found in normal HSC. LSCs have unique phenotype such as CD90-, CD117- and CD123+. Tumor-suppressor protein-death associated protein kinase and interferon regulatory factor 1 were overexpressed in LSCs, but not in normal HSC. Due to a predominantly G0 cell-cycle status, LSCs may not be responsive to conventional chemotherapeutic agents, compared with leukemia blasts. It is proposed that surviving LSCs are a major contributing factor to leukemic relapse. Although LSC population is likely to be drug-resistant, quiescent LSCs are preferentially susceptible to apoptosis induction while sparing normal HSC, with the appropriate stimulus such as proteasome inhibitor MG-132. This article reviewed the data emerging from the study of LSCs, and elucidated the distinct cellular and molecular characteristics of the LSC population, which may shed new light on AML therapy and leukemogenesis study.
