Reports from University of Tokyo Provide New Insights into Nanoparticles

June 24, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Data detailed on Nanoparticles have been presented. According to news reporting from Tokyo, Japan, by NewsRx journalists, research stated, "Although the use of small interfering RNA (siRNA) is a promising technique for gene regulation, spatiotemporal control of the effects of siRNA must be achieved if the technique is to be safe and practical. Here, a method for spatiotemporal regulation of genes with nanoparticles containing siRNA is reported."

The news correspondents obtained a quote from the research from the University of Tokyo, "The siRNA is encapsulated in photodegradable nanoparticles that are internalized to SKOV3-Luc cells, where the siRNA is released from the nanoparticles by UV irradiation for 30s. The encapsulated siRNA only shows no gene-silencing effects, but release of the siRNA upon UV radiation leads to sequence-specific silencing of the luciferase gene in the cells."

According to the news reporters, the research concluded: "These results indicate that photodegradable siRNA-containing nanoparticles can be useful for time-and space-dependent regulation of gene expression in cells."
