OBJECTIVETo construct lentivector carrying Tie2-Small interfering RNA (SiRNA), so as to study its influence on malignant melanoma cells.

METHODSRecombinant plasmid pSilencer 1.0-U6-Tie2-siRNA and plasmid pNL-EGFP were digested with XbaI, ligated a target lentiviral transfer plasmid of pNL-EGFP-U6-Tie2-I or pNL-EGFP-U6-Tie2-II, and then the electrophoresis clones was sequenced. Plasmids of pNL-EGFP-U6-Tie2-I and pNL-EGFP-U6-Tie2-II were constructed and combined with pVSVG and pHelper, respectively, to constitute lentiviral vector system of three plasmids. The Lentiviral vector system was transfected into 293T cell to produce pNL-EGFP-U6-Tie2- I and pNL-EGFP-U6-Tie2-II lentivirus. Then the supernatant was collected to determine the titer. Malignant melanoma cells were infected by both lentiviruses and identified by Realtime RT-PCR to assess inhibitory efficiency.

RESULTSThe recombinant lentiviral vectors of Tie2-RNAi were constructed successfully which were analyzed with restriction enzyme digestion and identified by sequencing. And the titer of lentiviral vector was 8.8 x 10(3)/ml, which was determined by 293T cell. The results of Realtime RT-PCR demonstrated that the lentiviral vectors of Tie2-RNAi could infect malignant melanoma cells and inhibit the expression of Tie2 genes in malignant melanoma cells (P<0.01). There was no significant difference in the expression level (P>0.05) between the two lentiviral vectors of Tie2-RNAi.

CONCLUSIONSLentivector carrying Tie2-SiRNA can be constructed successfully and inhibit the expression of Tie2 gene in vitro significantly. The study will supply the theory basis for the further research on the inhibition of tumor growth in vivo.

This study was aimed to investigate the characteristics of human bone marrow mesenchymal stem cells during ex-vivo expansion, MSCs were isolated from human bone marrow. At each passage, the characteristics of proliferation kinetics, osteogenic and adipogenic differentiation potential were analyzed, and cell morphology, surface markers were investigated as well. The karyotype analysis was done in different passage cells. The infection HIV, HCV, HBV and TP were detected by ELISA. Mycoplasma contamination in vitro was detected by PCR method. HLA-SBT was used to reanalyze the results of HLA antigens and alleles. STR genetic loci were detected by PCR in the MSC1, MSC2, MSC3 and MSC4. The results indicated that the proliferative ability and osteogenic potential decreased with the increase of passage number during culture expansion. The multiple differentiation potential of MSCs was maintained during their life span. Karyotype analysis showed that MSCs from 4 groups before passage 8 were normal. The expression of CD29, CD44, CD105, CD166 and CD73 were positive. The expression of CD14, CD34, CD45, CD80, CD86 were all negative. SBT was used to identify HLA-A, B, Cw, DRB1, DRPB1, DQ alleles in the MSC1, MSC2, MSC3, MSC4. The genetype of STR in the MSC1, MSC2, MSC3, MSC4 was different. MSC 3 was examined by TP-ELISA to confirm the infectious disease of TP. MSC2 was contaminated by mycoplasma at passage 5. It is concluded that culture expansion causes MSCs to gradually lose their stem cell properties. During ex-vivo expansion of MSCs, the osteogenic differentiation potential is decreased. MSCs before passage 8 can be a valuable subject for basic research and clinical application.

The complete genomic sequence of a watermelon isolate of Cucumber green mottle mosaic virus (CGMMV-LN) in Liaoning province was determined and compared with other cucurbit-infecting tobamoviruses. The genomic RNA of CGMMV-LN comprised 6422 nt, and 5'- and 3'- noncoding regions consisted of 59 nt and 175 nt, respectively. The encoded four proteins were two replicase proteins of 186 kD and 129 kD, move protein of 29 kD and coat protein of 17.4 kD. The alignment results of complete nucleotide sequence showed that CGMMV-LN shared identities of 97.6%-99.3% with four other CGMMV isolates, but only shared identities of 61.7%-62.8% with three other tobamoviruses. Homology trees generated from replicase proteins of 186 kD and coat proteins suggested that cucurbit-infecting tobamoviruses could be separated into two subgroups: subgroup I comprising all the isolates of CGMMV and subgroup II comprising Cucumber fruit mottle mosaic virus, Kyuri green mottle mosaic virus and Zucchini green mottle mosaic virus.

Sinocalycanthus chinensis, an endangered species endemic to China, is cultivated as an ornamental landscape tree in China. However, S. chinensis, Chimonanthus species and Calycanthus floridus are difficult to be distinguished in seedling market because of their similar morphological characters. In this study, ISSR (inter-simple sequence repeats) were applied to detect S. chinensis from its closely related species. A unique 748-bp band was found in all accessions of S. chinensis. SCAR (sequence characterized amplified regions) markers were created by cloning and sequencing the specific band, and designing a pair of primers to amplify the band of 748 bp. Diagnostic PCRs were performed using the primer pair with the total DNAs of S. chinensis, Chimonanthus species and C. floridus as templates, with only S. chinensis being able to be amplified. This amplification is not only rapid (results can be obtained in less than 3 h), but is also easy to perform. Hence it is a feasible method for identifying S. chinensis in seedling market.

OBJECTIVETo study possible influences of 1,25(OH)(2)D(3) on endothelial cell proliferation, apoptosis and endothelial nitric oxide synthase (eNOS) expression of aorta in apolipoprotein E-deficient (apoE(-/-)) mice and to explore the relationship between vitamin D and atherosclerosis.

METHODEndothelial cell of aorta in apoE(-/-) mice were isolated and cultured, and the influence of 1,25(OH)(2)D(3) on endothelial cell proliferation were observed by MTT, apoptosis of cells were quantitated by terminal deoxynucleotidyl transferase mediated dUTP nick end labelling, Bcl-2 mRNA, fas mRNA and eNOS mRNA was detected by reverse transcription-polymerase chain reaction.

RESULTEndothelial cell proliferation rate of aorta did not significantly change in the two control groups (0.162 ± 0.031 vs. 0.158 ± 0.006, P > 0.05). Compared with control groups, 1,25(OH)(2)D(3) stimulated endothelial cell proliferation of aorta (P < 0.05), but endothelial cell proliferation rate did not significantly change in different 1,25(OH)(2)D(3) concentration groups [1,25(OH)(2)D(3) concentration: 10(-4)mol/L, 10(-5) mol/L, 10(-6) mol/L, 10(-7) mol/L, 10(-8) mol/L, endothelial cell proliferation rate: 0.189 ± 0.013 vs. 0.285 ± 0.011 vs. 0.296 ± 0.026 vs. 0.284 ± 0.017 vs. 0.233 ± 0.010, P > 0.05]. 1,25(OH)(2)D(3) research concentration as chosen as 10(-6) mol/L. In 1,25(OH)(2)D(3) 10(-6) mol/L group, the expression of Bcl-2, eNOS mRNA was significantly increased (0.78 ± 0.16 vs. 0.46 ± 0.21 vs. 0.42 ± 0.17, 0.56 ± 0.16 vs. 0.39 ± 0.13 vs. 0.35 ± 0.11, 0.46 ± 0.2 vs. 10.42 ± 0.17 vs. 0.78 ± 0.16, 0.79 ± 0.21 vs. 0.81 ± 0.20 vs. 0.43 ± 0.12), apoptotic index, Fas mRNA was significantly decreased (15.14 ± 3.19 vs. 18.94 ± 4.22 vs. 19.27 ± 4.58, 0.43 ± 0.12 vs.0.79 ± 0.21 vs. 0.81 ± 0.20)(P < 0.05). The quantity of eNOS gene expression was inversely associated with apoptosis index and Fas mRNA, was positively associated with Bcl-2 mRNA (r = -0.676, -0.758, 0.762, P < 0.01).

CONCLUSION1,25(OH)(2)D(3) stimulated endothelial cell proliferation, inhibited apoptosis and increased eNOS expression of aorta in apoE(-/-) mice. These results may deepen understanding of the pathogenesis of atherosclerosis.
