Abstract

Previously, we have established an in vivo electroporation method for gene transfer into muscle by injection of DNA with a needle followed by electric pulse delivery using needle-type electrodes and proved that this method is effective for the systemic delivery of cytokines. To perform the needleless gene delivery, we combined jet injection of DNA with electroporation using plate-type electrodes. For delivery of beta-galactosidase- and enhanced green fluorescent protein (EGFP)-expressing plasmids into muscles, there was no significant difference between the previous needle-mediated method and the newly developed jet-injection method. When pCAGGS-IL-5 was introduced into tibialis anterior, quadricipital and back sural muscles by this new method, the serum IL-5 levels reached 3.4 +/- 0.9, 5.7 +/- 1.7 and 8.4 +/- 2.7 ng/ml at day 5, respectively. Although the peak values of IL-5 achieved by the jet-injection method in these muscles were lower than that of the highest value achieved by needle-mediated gene delivery into anterior tibial muscle, this new method could deliver plasmid into relatively large muscles with better efficiency than the needle-mediated method. Thus the jet-injection method provides a useful means of gene deliv...Continue Reading

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
