Résumé
Objectiveezrin gene is overexpressed in pancreatic cancer, and its upstream sequence plays an important role in gene expression. This study intends to knock out ezrin transcriptional regulatory region and identify its gRNA target sites for gene editing in pancreatic cancer cells.MethodsThe reporter gene expression vectors carrying the upstream segment of ezrin gene were transiently transfected into Panc-1 cells. The ezrin transcriptional regulatory regions were identified by double luciferase reporter gene detection system. Then, the online software was utilized to predict the gRNA target sites located at the upstream and downstream of ezrin transcriptional regulatory region. Two recombinant plasmids pX459-sgRNA-L and pX458-sgRNA-R contained these two sequences were constructed for gene editing. Moreover, in order to identify the targeted knockout of ezrin transcriptional regulatory region, the recombinant plasmids were co-transfected into Panc-1 cells, and the genome DNA contained gRNA target sites were amplified, subcloned and sequenced. Finally, Panc-1 cells transfected with recombinant plasmids were preliminary sorted using puromycin treatment. The cell proliferation was detected by water-soluble tetrazolium salt method.ResultsLuciferase data showed that ezrin gene fragment -1297/-1186 enhanced the transcriptional activity of SV40 promoter and ezrin promoter in Panc-1 cells. Subclonal sequencing data revealed that the recombinant plasmids carrying the gRNA target sequence of ezrin transcriptional regulatory region were co-transfected into Panc-1 cells could trigger the genomic DNA fragments, which located between gRNA-L and gRNA-R target sites. Cell proliferation assay showed that the proliferation was significantly inhibited after transfection.ConclusionThe targeted knockout of ezrin transcriptional regulatory region was achieved and the inhibition of Panc-1 cell proliferation may be related to this knockout.

OBJECTIVES@#To explore the micro-plastic operative treatment of deviated nose combined with nasal septum deviation.@*METHODS@#We designed the incision at the caudal side of the nasal septum. The three-line reduction method for correcting nasal septum deviation was performed. The connection of the caudal nasal septum and the anterior nasal spine was reposited. The micro-plastic surgery with fixed suture was used to correct the deviated nose.@*RESULTS@#After the surgery, the nasal septum deviation was corrected, whose nasal function and symptoms improved without nasal adhesion, nasal septum perforation or other complications. Meanwhile, the nasal tips were in the middle place and nasal dorsums were straight. The aesthetic outcome was satisfactory.@*CONCLUSIONS@#Compared to the traditional orthopedic technique, the micro-shaping technique can be used for the homochromous operation of crooked nose combined with nasal septum deviation with less injury and lower risk. We suggest this micro-shaping technique be used in a rational way.

OBJECTIVE: The change of DNA methylation of thymocyte differentiation antigen-1( Thy-1) was observed in beryllium sulfate( Be SO4) stimulated human fetal lung fibroblast( MRC-5 cell) to explore the effects of Thy-1 in Be SO4 induced lung fibrosis. METHODS: MRC-5 cell culture in vitro model was used. The final concentrations of Be SO4were1. 0,10. 0 and 100. 0 μmol / L( low-,medium- and high-dose groups). The control was untreated. Other 2 intervention groups were the 5-azacytidine( AZC) intervention group( 10. 0 μmol / L of AZC and 10. 0 μmol / L Be SO4) and the trichostatin A( TSA) intervention group( 0. 5 μmol / L of TSA and 10. 0 μmol / L Be SO4). The cells were collected 24,48 and 72 hours after exposure. Real-time quantitative polymerase chain reaction( PCR) was used to determine the relative expression of collagen typeⅠ( Col Ⅰ),collagen type Ⅲ( Col Ⅲ),α-smooth muscle actin( α-SMA) and Thy-1 mRNA.The nested landed methylation specific PCR was used to detect the Thy-1 DNA methylation level. RESULTS: At 24 hours,the relative expression level of Col Ⅲ mRNA in MRC-5 cells showed an increasing trend with increasing dose( P < 0. 05);at 48 and 72 hours,the relative expression levels of Col Ⅰ,Col Ⅲ and α-SMA mRNA in MRC-5 cells increased with the increasing dose( P < 0. 05). All these 3 indicators in MRC-5 cells of 3 dose groups increased with the increase of expose time( P < 0. 05). The relative expression level of Thy-1 mRNA in MRC-5 cells of all 3 dose groups were lower than that in control( P < 0. 05). The relative expression level of Thy-1 mRNA of the high-dose group was lower than that of the lowdose group( P < 0. 05). The Thy-1 DNA methylation levels in the medium- and high-dose groups were both higher than that of the control( P < 0. 05). The Thy-1 DNA methylation levels of the 3 dose groups increased with the increasing dose( P < 0. 05). The Thy-1 DNA methylation levels of MRC-5 cells in the 2 intervention groups were higher than that of the control( P < 0. 05),but there was no significant difference when compared with the medium-dose group( P > 0. 05).CONCLUSION: Be SO4 stimulation can induce the fibrosis of MRC-5 cells. In this process,the Thy-1 DNA methylation level increases,while the Thy-1 mRNA expression level decrease. Thy-1 DNA methylation might be one of the important mechanisms of lung fibrosis induced by Be SO4.
