This paper aims to provide a concise review on the study of a gene delivery system with layered double hydroxides (LDH) as carrier. The issues, such as preparation and cytobiology effect of LDH-DNA hybrids, and the release mechanism of DNA from LDH-DNA complex, were discussed in detail. For achieving a ideal cell transfection efficiency, it would be prospective to improve both the intercalation effect of giant DNA, such as plasmid DNA and long chain DNA fragments, and the gene transfection technique of small DNA fragment.

AbstractWe have developed new gene expression-regulating polymer that can activate transgene expression in response to target intracellular signals. Here, we tried applying sonoporation system to this gene regulation system to enhance the gene expression efficacy. Sonoporation is the method for effective gene transfection in vitro and in vivo. Therefore, the method might enhance the transfection efficiency in our polymer and realize an efficient and safe gene delivery system. Results suggested that the combination of our polymer and sonoporation could improve the gene expression compared to the system using only our polymer that transfers genes into cells via endocytosis. It also kept the ability of the gene regulation responding to cellular signals.

The key strategy for the advancement of gene therapy is the development of an efficient targeted gene delivery system into cells. The targeted gene delivery system is especially important in non-viral gene transfer which shows the relatively low transfection efficiency. It also opens the possibility of selective delivery of therapeutic plasmids to specific tissues. Chitosan has been considered to be a good candidate for gene delivery system, since it is already known as a biocompatible, biodegradable, and low toxic material with high cationic potential. However, low specificity and low transfection efficiency of chitosan need to be overcome prior to clinical trial. In this study, we focused on the chemical modification of chitosan for enhancement of cell specificity and transfection efficiency. Also, the potential of clinical application was investigated.

Vectors are vital aspect of gene delivery system which decides the success of gene therapy. Efficient transfection with minimum or no toxicity, are two principal aims of any gene delivery system. In this our study, we rationally developed biodegradable water soluble poly(ßamino ester) (PAE) based on spermine (SPR) and poly (ethylene glycol) (PEG), by Michael-type addition reaction and further studied for its potential as a gene carrier. Confirmation of synthesized PAE was done by proton NMR spectroscopy. In gel retardation assay, the PAEs have shown good DNA binding ability over wide range of polyplexes. The addition of PEG over SPR resulted in a novel PAE with higher degree of safety and transfection efficiency as compared with polyethylenimine 25K (PEI) when studied in 293T human kidney carcinoma cells.
