Objective Abnormal activation of mitogen-and stress-activated kinase (MSK1) plays an important role in the development of various cancers.This study was to explore the effect of small interfering RNA (siRNA)-mediated MSK1-silencing on the proliferation of human nasopharyngeal carcinoma (NPC) cells and its underlying mechanism.Methods The siRNA vector targeting MSK1 was constructed and transfected into CNE2 cells, and the NPC cell line stably expressing MSK1 was established.Then the cells were divided into a blank control (without transfection of the plasmid), a negative control (with stable transfection of the negative control plasmid), and an experimental group (with stable transfection of the positive recombinant plasmid).The expressions of MSK1 mRNA and protein were detected by real-time quantitative PCR and Western blot, respectively, the proliferation of the cells determined by CCK-8 and colony formation assays, the cell cycles analyzed by flow cytometry, the level of histone H3 phosphorylation at Ser10 examined by Western blot, and The transcriptional activity and expression of the c-jun protein measured by dual-luciferase reporter gene assay and Western blot.Results Compared with the blank control, the inhibition rates of cell proliferation at 48, 72 and 96 hours were significantly reduced in the experimental group (P<0.05), and so were the colony formation ability of the cells (P<0.01) and the expression and transcriptional activity of the c-jun protein (P<0.05).In comparison with the negative control, the experimental group showed significant decreases in the rate of cell growth after 24 hours, the inhibition rates of cell proliferation at 48, 72 and 96 hours (P<0.05), the number of formed colonies ([221.00±20.08] vs [99.67±15.57] / 300 cells, P<0.01), the proportion of S-phase cells (P<0.01), and the expression of the c-jun protein in the CNE2 cells ([100.00±0.00] vs [48.77±10.71] %, P<0.05), but a remarkable increase in the percentage of G0/G1-phase cells (P<0.01).Furthermore, histone H3 phosphorylation at Ser10 was markedly reduced (P<0.01) but no significant change was observed in the expression of the total c-jun protein in the experimental group.Conclusion Knockdown of MSK1 using siRNA can significantly inhibit the growth and proliferation of CNE2 cells, which may be closely related to the decreased phosphorylation of histone H3 and subsequently down-regulated transcriptional activity of c-jun.

Objective To investigate the relationship between glucokinase regulator protein ( GCKR) gene polymorphism rs780094 and hyperuricemia in Uygur in Xinjiang. Methods A case-control study including 1 026 patients with hyperuricemia and 1 030 normal subjects was conducted. All the subjects were genotyped for GCKR gene rs780094 by Sequenom MassARRAY system. The results of rs780094 genotype and allele frequency between hyperuricemia group and control group were compared. The associations of different genotypes of rs780094 with blood pressure, blood lipid, and blood glucose were analyzed. Logistic regression analysis was used to analyse the relationship between polymorphism of rs780094 and hyperuricemia in Uygur in Xinjiang. Results The distributions of three genotypes(G/G, A/G, A/A) and two allele frequency (G and A) in GCKR rs780094 revealed statistical difference ( P<0. 05 ) between hyperuricemia group and control group. A tendency toward association with hyperuricemia was observed under dominant model(OR=1. 295, 95%CI 1. 078~1. 554,P=0. 006) and recessive model(OR=1. 284, 95% CI 1. 024 ~1. 611,P=0. 030). The levels of systolic blood pressure, diastolic blood pressure, and total cholesterol were lower in hyperuricemia group with GCKR gene rs780094 loci GG genotype than those with AA+AG genotype. After adjusting confounding factors which had significant difference in the single factor analysis, logistic regression analysis showed that rs780094 A/A and A/G might be risk factors of hyperuricemia in Uygur in Xinjiang (OR=1. 355,95% CI 1. 094 ~1. 679,P=0. 005). Conclusion The GCKR rs780094 is associated with hyperuricemia in Uygur in Xinjiang. The A/A and A/G genotype of the GCKR rs780094 may increase the risk of hyperuricemia.

Objective To find out technological evidence for the rapid propagation of Aloe vera L.var.chinensis (Haw.)Berber. Methods The technique of plant tissue culture was used to study the rapid propagation of Aloe vera L.Var.Chinesis(Haw.)Berger.The shoot growing from the underground stem of Aloe vera L.Var.chinensis(Haw.)Berger was taken as the explant to induce fascicular bud. Results The optimal culture medium was MT.MT culture medium added with 6-benzylaminopurine(BA) was effective to induce the shoot formation and increase the direct shooting rate.The optimal BA concentration for the induction and formation of shoot was 2 mg?L -1 ,the shooting rate being 100%.As for the induction of rooting,MT culture medium adding with 0.5 mg?L -1 naphthalene acid was optimal,the rooting rate being 100%. Conclusion The culture of Aloe shoot growing from the underground stem,proper culture medium and BA concentration are important for the rapid propagation of Aloe.

AIM: To detect the protein expression of TIMP3 and RUNX3 in bone marrow mononuclear cells (BMMCs) from acute leukemia (AL) patients and to investigate the relationship between the methylation status of genes and their expressional levels. METHODS: Protein expression of TIMP3 and RUNX3 in 50 samples of BMMCs and 10 samples of peripheral blood mononuclear cells (PBMCs) from healthy volunteers was detected by Western blotting. The prognostic factors related to AL and data from methylation specific polymerase chain reaction were also analyzed. RESULTS: The expression level of RUNX3 with methylation was less than that without methylation in BMMCs from AL patients. The complete remission (CR) rate was related to RUNX3 expression and blasts in bone marrow (BM). BMMCs from patients with silencing of RUNX3 and higher blasts in BM had a lower CR rate. CONCLUSION: Absence of RUNX3 protein expression resulting from methylation of RUNX3 promoter probably plays a role in the pathogenesis of AL and is of value in prognosis. No relationship between methylation of TIMP3 promoter and the pathogenesis of AL is observed.

Objective To investigate the molecular mechanism of resistance to carbapenems in Pseudomonas aeruginasa from 5 teaching hospitals in Beijing. Methods A total of 213 non-duplicate imipenem-resistant Pseudomonas aernginosa (IRPA) isolates were collected from 5 hospitals in Beijing from June 2004 to December 2005. The minimal inhibitory concentrations (MICs) of meropenem, imipenem and others antibiotics were determined by agar dilution method. Disk diffusion test was used for screening metalloenzymes. The bla IMP,bla VIM and OprD2 genes were amplified by PCR and only sequenced.
