Studies from National Center for Scientific Research (CNRS) Further Understanding of Essential Amino Acids (Improved gene transfer with histidine-functionalized mesoporous silica nanoparticles)

By a News Reporter-Staff News Editor at Drug Week -- Investigators discuss new findings in Essential Amino Acids. According to news originating from Orleans, France, by NewsRx correspondents, research stated, "Mesoporous silica nanoparticles (MSN) were functionalized with aminopropyltriethoxysilane (MSN-NH2) then L-histidine (MSN-His) for pDNA delivery in cells and in vivo."

Our news journalists obtained a quote from the research from National Center for Scientific Research (CNRS), "The complexation of pDNA with MSN-NH2 and MSN-His was first studied with gel shift assay. pDNA complexed with MSN-His was better protected from DNase degradation than with MSN-NH2. An improvement of the transfection efficiency in cells was observed with MSN-His/pDNA compared to MSN-NH2/pDNA, which could be explained by a better internalization of MSN-His."

According to the news editors, the research concluded: "The improvement of the transfection efficiency with MSN-His was also observed for gene transfer in Achilles tendons in vivo."
