Popis: Plasmid DNA (pDNA) is attractive molecule for gene therapy. pDNA-targeted delivery by efficient and safe methods is required to enhance its intra-tissue bioavailability. Among non-viral methods, sonoporation has become a promising method for in-vitro and in-vivo pDNA delivery. The efficiency of non-viral delivery methods of pDNA is generally limited by the presence of serum.The aim of this study was to evaluate the influence of serum on in-vitro pDNA delivery using microbubble-assisted ultrasound.The effects of a range of serum concentrations (0-50%) on efficiency of in-vitro pDNA delivery by sonoporation were determined on human glioblastoma cells. Furthermore, the influence of the serum on cell viability, membrane permeabilization, microbubble destruction, and pDNA topology were also assessed.In-vitro results showed that a low serum concentration (i.e. ≤1%) induced a significant increase in transfection level through an increase in cell viability. However, a high serum concentration (i.e. ≥5%) resulted in a significant decrease in cell transfection, which was not associated with a decrease in membrane permeabilization or loss in cell viability. This decrease in transfection level was in fact positively correlated to changes in pDNA topology.Serum influences the efficiency of in-vitro pDNA delivery by sonoporation through change in pDNA topology.
