OBJECTIVETo construct and identify a lentiviral vector of RNA interference targeting human Notch-1 gene.
METHODSTo determine the Notch-1 gene sequences, three RNAi target sequences (shRNA1-3) were designed in accordance with the RNAi sequence design principles and cloned into the lentiviral vector pLenOR-THM by endonuclease BamH I restriction, EcoR I double digestion, and T4 DNA-ligase ligation. After the transformation into competent DH5alpha bacteria, the candidate clones were identified by Kpn I and EcoR I double digestion and DNA sequencing. The recombinant and three packaging plasmids were co-transfected into human embryonic kidney cell line 293T cells by lipofectamine to produce the lentiviral particles. The viral titer was determined. The 293T cells were infected by the lentiviral particles obtained, and transfection efficiency was assessed using a fluorescent microscope. The lentiviral vector particles were also transfected into ACC-M cells. The Notch-1 expression in the transfected cells was assayed by quantitative reverse transcription polymerase chain reaction (QRT-PCR) and Western blot analysis.
RESULTSThe lentiviral RNAi vector pLenOR-THM-Notchl for Notch-1 gene was constructed successfully. Strong green fluorescence was observed in the 293T cells under fluorescent microscope after co-transfection of the cells with the four plasmids of lentiviral vector. The virus in the supernatant reached a titer of 5.8 x 10(8) TU x mL(-1). The transfection efficiency of the collected virus exceeded 90% in 293T cells with 1 as a multiplicity of infection. The third lentiviral vector was found to significantly inhibit the Notch-1 expression at the mRNA and protein levels.
CONCLUSIONThe lentiviral RNAi vector of Notch-1 has been successfully constructed and identified.

Objective To investigate the relationship between polymorphism of NAD (P)H quinone oxidoreductase 1 (NQO1)and X-ray repair cross-complementing group 1 (XRCC1) and their correlation with smoking on the susceptibility to gastric cancer. Methods A 1:1 case-control study of 334 patients with primary gastric cancer, with non-cancer or alimentary inpatients as control group (matched for ages ± 5 years, sex and reqion) in Anhui province was conducted to analyze theNQO1C609T and XRCC1G28152A. Gene types by PCR-based restriction fragment length polymorphism techniques. Interaction index (γ) was calculated to determine the type of gene- environment interaction. Results The average age of 334 cases of gastric cancer patients was 57 years, with 65.3% of them were male. Smoking rate in the case group (55.09%) was significantly higher than in the control group (36.53%). The consequence showing that it carried the heterozygous variant (CT)or homozygous variant (TT) of NQO1 could enhance the risk of gastric cancer(OR= 1.507,3.050),but not the XRCC1G28152A gene polymorphism or the susceptibility to gastric cancer. At the same time,individuals that carrying XRCC1AG and NQO1TT could increase 2.789 times the incidence of gastric cancer than those who carrying the XRCC1AG or NQO1CC. The gastric cancer risk of XRCC1GG individuals that carrying NQO1TT was 4.448 times higher than those who carrying XRCC1GG or NQO1 CC. The positive interactions of NQO1 homozygous variant (TT) , XRCC1 homozygous variant (GG) and smoking were revealed in the occurrence rates of gastric cancer (OR=3.094,γ =2.070). Conclusion Our research findings showed that the significant interactions between genetic polymorphisms of NQO1, XRCC1 and smoking added the risk of gastric cancer, while genetic and environmental hazardous factors co-effecting the development of gastric cancer.

An offline two-dimensional system combining a rat cardiac mascle cell membrane chromatography time-of-flight mass spectrometry (CMC-TOF/MS) with a high performance liquid chromatography time-of-flight mass spectrometry (HPLC-TOF/MS) was established for investigating the parent components and metabolites in rat urine samples after administration of the roots of Aconitum carmichaeli. On the basis of the analysis of the first dimension, retention components of the urine sample were collected into 30 fractions (one fraction per minute). Then offline analysis of the second dimension was carried out. 34 compounds including 24 parent alkaloids and 10 potential metabolites were identified from the dosed rat urine, and then binding affinities of different compounds on cell membranes were compared and influences of some functional groups on activity were estimated with the semi-quantification and curve fitting method. As a result, binding affinities decreased along with the process of deacylation, debenzoylation and demethylation, which may be related to the alleviation of toxicity in the procedure of herb processing or metabolism. Moreover, some minor components in rat urine (Songorine, 14-benzoylneoline, Deoxyaconitine, etc. ) exerted relatively strong affinity on cell membranes are worth exploring. The results delivered by the system suggest that the CMC can be applied to in vivo study.
