Finally, untreated cells (no transfection or transduction) provide a reference for the treated cells and will allow you to determine the cytotoxicity of a particular siRNA delivery method. This creates a new dsRNA, which is then processed by Dicer, creating a positive feedback loop that increases the pool of siRNAs. It was eventually determined that the miRNA pathway involved many of the same protein components as the RNAi pathway. Lipofectamine 3000, to A498 cells [32]. The positive surface charge of the liposomes formed by Lipofectamine/RNA mixtures allows for the fusion of liposome/nucleic acid complexes with the negatively charged cell. shRNA itself may cause non-specific effects in the infected cells, so a non-targeting scrambled shRNA is needed as a control. An interesting feature of this system in some organisms is that annealing of the siRNA to the target mRNA allows the siRNA to act as a primer, while the target mRNA acts as a template for an RNA-dependent RNA-polymerase. These initial precursors are processed by Drosha and its dsRNA-binding partner DGCR8, resulting in species known as pre-shRNAs, before being exported to the cytoplasm by Exportin-5. A Cells were lentivirally transduced with either scrambled sequence (control) or FAP shRNA for 4 days followed by CCK-8 assay to determine cell viability. Copyright 2022 OriGene Technologies, Inc.
