Gene silencing by RNAi in mouse Sertoli cells
BACKGROUND RNA interference (RNAi) is a valuable tool in the investigation of gene function. The purpose of this study was to examine the availability, target cell types and efficiency of RNAi in the mouse seminiferous epithelium. METHODS The experimental model was based on transgenic mice expressing EGFP (enhanced green fluorescent protein). RNAi was induced by in vivo transfection of plasmi...
متن کاملRNAi-Mediated Gene silencing in Zebrafish Triggered by Convergent Transcription
RNAi based strategies to induce gene silencing are commonly employed in numerous model organisms but have not been extensively used in zebrafish. We found that introduction of transgenes containing convergent transcription units in zebrafish embryos induced stable transcriptional gene silencing (TGS) in cis and trans for reporter (mCherry) and endogenous (One-Eyed Pinhead (OEP) and miR-27a/b) g...
متن کاملAnalysis of insulin signalling by RNAi-based gene silencing.
Using siRNA-mediated gene silencing in cultured adipocytes, we have dissected the insulin-signalling pathway leading to translocation of GLUT4 glucose transporters to the plasma membrane. RNAi (RNA interference)-based depletion of components in the putative TC10 pathway (CAP, CrkII and c-Cbl plus Cbl-b) or the phospholipase Cgamma pathway failed to diminish insulin signalling to GLUT4. Within t...
متن کاملGene Silencing in Insect Cells Using RNAi.
A technique is described for synthesizing and transfecting double stranded RNA (dsRNA) for RNA interference (RNAi) in Sf-21 cell culture. Transfection with dsRNA only requires an hour and the cells usually recover within 12 h. Suggestions for designing dsRNA are included in the methods. Furthermore, websites are provided for rapid and effective dsRNA design. Three kits are essential for using t...
متن کاملTomato and Tobacco Phytoene Desaturase Gene Silencing by Virus-Induced Gene Silencing (VIGS) Technique
Background and Aims: Virus-Induced Gene Silencing (VIGS) is a virus vector technology that exploits antiviral defense mechanism. By infecting plants with recombinant viruses containing host genes inserted in the viral genome, VIGS achieves the RNA silencing process. The purpose of this study was to investigate the possibility of tomato (Lycopersicon esculentum Mill.) and tobacco (Nicotiana be...
