RNA interference (RNAi) is a sequence-specific gene-silencing mechanism triggered by double-stranded RNA. RNAi was shown to allow transient or stable knockdown of gene expression in a broad range of species and has been used successfully for functional genomic screens in mammalian cells and Caenorhabditis elegans. Standard therapeutic use of RNAi in clinical settings in humans has been hampered...
Non-viral gene delivery is plagued by low transfection levels compared to viral delivery. The nuclear envelope presents a significant obstacle for non-viral vectors. A peptide-based nuclear localizing sequence has been incorporated into non-viral vectors to traverse the nuclear envelope. Here, we selected a photo-chemical method for covalently labeling the peptide onto plasmid DNA. The hypothes...
Interleukin-22 (IL-22) is a recently identified T cell-derived cytokine whose biological significance remains obscure. Previously, we have shown that IL-22 plays a protective role in T cell-mediated hepatitis induced by Concanavalin A (Con A), acting as a survival factor for hepatocytes. In the present paper, we demonstrate that hydrodynamic gene delivery of IL-22 cDNA driven either by a liver-...
objective polyethylenimine (pei), a readily available synthetic polycation which has high transfection efficiency owing to its buffering capacity was introduced for transfection a few years ago. but it has been reported that pei is cytotoxic in many cell lines. in this study, in order to enhance the transfection efficiency of 10 kda pei and reduce its toxicity, hydrophobic residues were grafted...
Hydrodynamics-based delivery has been used as an experimental tool to express transgene in small animals. This in vivo gene transfer method is useful for functional analysis of genetic elements, therapeutic effect of oligonucleotides, and cancer cells to establish the metastatic cancer animal model for experimental research. Recent progress in the development of image-guided procedure for hydro...
