Short-term expression of transgenes is one of the problems frequently associated with non-viral in vivo gene transfer. To obtain experimental evidence for the design of sustainable transgene expression systems, the contribution of epigenetic modifications to the decline in transgene expression needs to be investigated. Bisulfite sequencing and reactivation by hydrodynamic injection of isotonic ...

The key principle of gene delivery to articulations by direct intra-articular injection is to release complementary DNA(cDNA)-encoding medical products that will lead to maintained, endogenous production of the gene products withinthe articulation. In fact, this has been accomplished for both in vivo and ex vivo gene delivery, using several vectors,genes, and cells in some animal models. Some c...

This work describes a versatile and universal polycation system based on oligoamines grafted on natural polysaccharides that is capable of complexing various plasmids and administering them into various cells in high yield to produce a desired protein. These polycations are expected to better meet the requirements for effective complexation and delivery of plasmid or an antisense and to biodegr...

Agents that safely and efficiently deliver nucleic acids into the cells are critical to successful gene therapy. Cationic and amphiphilic nature of the lipofectin molecules allow stable formation of complexes with DNA and also efficient delivery DNA into cells. To a large extent the cationic l ipids that are in vogue are synthesized using glycerol as the backbone. These have led to very useful ...
