Objective To silence human gene Set7/9 and screen out stable transfection cell line in hepatocellular carcinoma cell line HepG2 so as to investigate the impact of down-regulation of Set7/9 in cell line HepG2 and provide experimental foundation for studies on the effect of set7/9 in HepG2.Methods The target oligo was designed and synthesized;shRNA interference vector and the control vector were constructed and transfected into HepG2 cells;the stable transfection cells were screened out.Then Real-time PCR and Western blot were performed to detect the silence of Set7/9 according to both gene expression and protein expression level. Results The shRNA interference vector was constructed and transfected into HepG2 cells successfully.Compared with that in the negative control group,the expression of Set7/9 was dramatically downregulated (P < 0.05 ). Meanwhile,the expression of related protein Sirt1 and Suv39h1 was upregulated 8.4 folds and 1.1 fold, respectively.Conclusion Downregulation of Set7/9 expression can upregulate Sirt1 and Suv39h1,suggesting that Set7/9 may affect the activity of HepG2 cell lines.

The present study is to establish Caco-2/HT29-MTX co-cultured cells and investigate the transport capability of PLGA nanoparticles with different surface chemical properties across Caco-2/HT29-MTX co-cultured cells. PLGA-NPs, mPEG-PLGA-NPs and chitosan coated PLGA-NPs were prepared by nanoprecipitation method using poly(lactic-co-glycolic acid) as carrier material with surface modified by methoxy poly(ethylene glycol) and chitosan. The particle size and zeta potential of nanoparticles were measured by dynamic light scattering. Coumarin 6 was used as a fluorescent marker in the transport of nanoparticles investigated by confocal laser scanning microscopy. The transport of furanodiene (FDE) loaded nanoparticles was quantitively determined by high performance liquid chromatography. Colchicine and nocodazole were used in the transport study to explore the involved endocytosis mechanisms of nanoparticles. Distribution of the tight junction proteins ZO-1 was also analyzed by immunofluorescence staining. The results showed that the nanoparticles dispersed uniformly. The zeta potential of PLGA-NPs was negative, the mPEG-PLGA-NPs was close to neutral and the CS-PLGA-NPs was positive. The entrapment efficiency of FDE in all nanoparticles was higher than 75%. The transport capability of mPEG-PLGA-NPs across Caco-2/HT29-MTX co-cultured cells was higher than that of PLGA-NPs and CS-PLGA-NPs. Colchicine and nocodazole could significantly decrease the transport amount of nanoparticles. mPEG-PLGA-NPs could obviously reduce the distribution of ZO-1 protein than PLGA-NPs and CS-PLGA-NPs. The transport mechanism of PLGA-NPs and mPEG-PLGA-NPs were indicated to be a combination of endocytosis and paracellular way, while CS-PLGA-NPs mainly relied on the endocytosis way. PEG coating could shield the surface charge and enhance the hydrophilicity of PLGA nanoparticles, which leads mPEG-PLGA-NPs to possess higher anti-adhesion activity. As a result, mPEG-PLGA-NPs could penetrate the mucus layer rapidly and transport across Caco-2/HT29-MTX co-cultured cells.

In this paper, three spoilage organisms were separated from five transmutative soy milks, and all the three spoilage bacteria could survive condition of both 1?105Pa,30min and 300mg/kg Nisin. Morpha character, physiological and biochemical characteristics, and a phylogenetic analysis based on 16S rDNA gene sequences reveal that these three strains are Bacillus licheniformis, Bacillus pumilus and Brevibacillus borstelensis respectively. GenBank accessions for these three strains are EF439666-EF439668。
