Objective To detect the transferred vascular endothelial growth factor (VEGF)165 gene expression in rhesus autologous bone marrow mesenchymal stem cells (MSCs), and to explore the functional viability of transgenic MSCs. Methods MSCs from rhesus bone were isolated by Ficoll, which were used to detect the phenotype. After the culturing, the expression vector pcDNA-eGFP-VEGF165 was transfected into bone marrow MSCs. Fluorescence microscope and flow cytometry were used to detect the enhanced green fluorescent protein (eGFP) expression. At the same time, the phenotype in transfected MSCs was also indentified. The VEGF165 expression level was detected by RT-PCR. Results The highly purified MSCs were collected successfully. The transfected MSCs and daughter cells showed expressions of eGFP and VEGF165, which also remained the characteristics of MSCs. Conclusion The VEGF165 gene that is transfected into MSCs can maintain characteristics of MSCs, and stably express foreign genes.

In order to amplify pilA gene and ompC gene of avian pathogenic Escherichia coli (APEC) strain, two pairs of primers were designed according to the GenBank sequences, and a 549 bp pilA gene and a 1104 bp ompC gene were obtained by PCR separately. Sequence analysis indicated that the homology of the nucleotide sequence of AEPC strain to those other reference strains was 98.18% of the pilA gene and 97.28% of the ompC gene. Two expression plasmids pETpilA and pETompC were constructed by inserting pilA gene and ompC gene into the prokaryotic expression vector pET-28a. The two plasmids were transformated into E. coli BL21 separately and two recombinant strains BL21 (pETpilA) and BL21 (pETompC) were obtained. The type 1 fimbraie and the out membrane protein were highly expressed when the recombinant strain BL21 (pETpilA) and BL21 (pETompC) were induced by IPTG Two specific proteins were detected by SDS-PAGE and immunogenicity of the expressed protein was confirmed by Western blotting and ELISA. The expressed fimbraie and OmpC were transformed into vaccine. The protective immune response was proved after the mice were immunized with the two vaccines. The results showed that the recombinant strain BL21 (pETpilA) and BL21 (pETompC) could be as candidate vaccine to provide protective immune response against AEPC infection.

Estrogen Receptor (ERalpha) is a member of superfamily of ligand-activated transcription factors which play critical roles in many biological processes. To screen novel modulators of ERalpha for drug development and biological function research, we developed a mammalian one-hybrid-based high-throughput screening model for ERalpha modulator. We cloned the ERalpha LBD gene from the total mRNA of fat tissue by RT-PCR and fused it with the GAL4 DNA binding domain of pBIND-GAL4 plasmid to construct a chimara expression plasmid pBIND-GAL4-Eralpha(LBD). The L02 cells was cotransfected with pBIND-GAL4-ERalpha(LBD) and a GAL4-responsive luciferase reporter plasmid pGL3-GAL4, and following treatment with test compounds for 24 h, the activities of luciferase were detected to evaluate the transactivities of ERalpha modulators. After manner optimizations of transfection conditions, Estradiol, an agonist control, induced the expression of luciferase in a dose-dependent with EC50 of 0.17 micromol/L, the maximum folds of induction was about 28.1. Tamoxifen, an antagonist control, efficiently suppressed the estradiol-mediated luciferase induction with EC50 of 0.10 micromol/L. Using this screening model, we discovered four ERalpha agonists from 2000 natural and synthetic compounds.

The present study aims to explore the possible mechanisms that trichostatin A (TSA), a histone deacetylases inhibitor (HDACi), affects the inflammatory signaling pathways of lipopolysaccharide/toll-like receptor 4/nuclear factor-κB (LPS/TLR4/NF-κB). Murine macrophage cell line RAW264.7 cells were employed. MTT assay was used to assess cell viability. The contents of TNF-α, IL-1β and IL-6 in culture supernatant were assayed by enzyme-linked immunosorbent assay (ELISA). TLR4 expression and NF-κB/p65 (Lys310) acetylation were examined by Western blotting. DNA binding activity of NF-κB/p65 was detected by using TransAM(TM) NF-κB/p65 activity assay kit. The results showed that, compared with control group, which was treated by DMSO, the cells treated with TSA (20, 40, 80 ng/mL) showed decreased percentages of cell survival (P < 0.05). The contents of TNF-α, IL-1β and IL-6 in culture supernatant were all increased by LPS (100 ng/mL), whereas reduced by 40 ng/mL TSA pretreatment (P < 0.05). TSA pretreatment inhibited LPS-induced up-regulation of TLR4 protein expression. Acetylation of NF-κB/p65(Lys310), which was already increased by LPS, was further enhanced by TSA (P < 0.05). On the contrary, LPS-increased DNA binding activity of NF-κB/p65 was decreased by pretreatment with TSA (P < 0.05). The results suggest that TSA-induced anti-inflammation may be attributed to decreases in the expression of TLR4 and DNA binding activity of NF-κB/p65.

OBJECTIVETo investigate the molecular basis for a novel human leukocyte antigen (HLA) allele B*5827.
METHODSDNA from the proband was analyzed by polymerase chain reaction-sequence specific oligonucleotide (PCR-SSO) typing. The amplified product was sequenced bidirectionally.
RESULTSAbnormal HLA-B locus was observed and its nucleotide sequence was different from the known HLA-B allele sequences, with highest homology to HLA-B*5820 allele. It differs from HLA-B*5820 by 8 nucleotide substitutions in exon 3, i.e., nt 290 (G > C), nt 346 (T > A), nt 390 (A > C), nt 404 (G > C), nt 413 (C > G), nt 471 (A > G), nt 486 (A > G) and nt 487 (C > A), resulting in an amino acid change from ser > arg at nt 97, phe >tyr at nt 115, ser > arg at nt 130, thr > ala at nt 157 and thr > glu at nt 162. Nucleotide differences of nt 404 (G > C) and nt 413( C > G) did not change amino acid.
CONCLUSIONThe sequences of the novel allele have been submitted to GenBank (access No.GU071234). A novel HLA class I allele B*5827 has been officially assigned by the WHO HLA Nomenclature Committee in Jan. 2010.

BACKGROUNDIncreased triglyceride (TG) occurs in patients with acute coronary syndrome (ACS), and apolipoprotein AV (apoAV) has been shown to lower TG levels. In the present study, we investigated plasma apoAV level and its relationship with TG and C-reactive protein (CRP) in ACS patients.
METHODSA total of 459 subjects were recruited and categorized into control group (n = 116), stable angina (SA) group (n = 115), unstable angina group (n = 116) and acute myocardial infarction group (n = 112). Plasma apoAV level was measured by a sandwich ELISA assay.
RESULTSCompared with controls ((100.27 +/- 22.44) ng/ml), plasma apoAV was decreased in SA patients ((76.54 +/- 16.91) ng/ml) but increased in patients with unstable angina ((330.89 +/- 66.48) ng/ml, P < 0.05) or acute myocardial infarction ((368.66 +/- 60.53) ng/ml, P < 0.05). Inverse correlations between apoAV and TG were observed in the control or stable angina groups (r = -0.573 or -0.603, respectively, P < 0.001), whereas positive correlations were observed in the patients with unstable angina or acute myocardial infarction (r = 0.696 or 0.690, respectively, P < 0.001). Furthermore, a positive relationship between apoAV and CRP was observed in the ACS patients but not in the non-ACS subjects.
CONCLUSIONThe plasma apoAV concentration is increased and positively correlates with TG and CRP in ACS patients.
