New Data from Flinders University of South Australia Illuminate Findings in Gene Therapy

June 26, 2014

By a News Reporter-Staff News Editor at Gene Therapy Weekly -- Investigators discuss new findings in Biotechnology. According to news originating from Adelaide, Australia, by NewsRx correspondents, research stated, "To create advanced functional nanocarriers for achieving excellent gene delivery performance, fluorescence label-free hybridized dendrimer-like silica nanocarriers (HPSNs-AC-PEI) were developed by using the endosomal pH and cytoplasmic glutathione (GSH) responsive autofluorescent acetaldehyde-modified-cystine (AC) to link non-toxic low molecular weight branched polyethyleneimine (PEI) onto amino-functionalized dendrimer-like silica nanoparticles with hierarchical pores (HPSNs-NH2)."

Our news journalists obtained a quote from the research from the Flinders University of South Australia, "The specific microstructure of this hybridized nanocarrier makes it not only show low cytotoxicity and high gene loading capability, but also display high gene transfection efficiency. The cleavage of disulfide bonds caused by GSH facilitates plasmid DNA (pDNA) release."

According to the news editors, the research concluded: "Moreover, the pH and GSH controlled gene delivery profile can be real-time tracked using the autofluorescence of HPSNs-AC-PEI."
