CpG-DNA Delivery Using DNA Nanotechnology

Effective CpG DNA delivery using amphiphilic cycloamylose nanogels.

Unmethylated CpG oligodeoxynucleotides induce inflammatory immune responses through cytokine production and have attracted increasing attention as an immunostimulator. However, there remains a challenging issue of the use of 'native CpG DNA'. In the present study, we prepared cationic nanometer-sized gels (nanogels) consisting of cycloamylose modified with cholesterol and diethylaminoethane to ...

Predicting CpG Islands and DNA Methlation in the Cow Genome Using DNA Microarray Meta-Analysis and Genome Wide Scanning

DNA methylation is a type of epigenetic changes that directly affects DNA. In mammals, DNA methylation is essential for fetal development and stem cell differentiation and this phenomenon essentially occurs within the CpG islands. In this study, two methods were used to study the DNA methylation profile of cow genome. In the first method, the DNA methylation profile of the differentially expres...

DNA nanotechnology-based development of delivery systems for bioactive compounds.

Nucleic acids, DNA and RNA, not only allow transfer and replication of densely coded genetic information, but also act as danger signals triggering innate immune response. Recent progress in the design and construction of nano-sized structures using DNA has opened a new field of nanotechnology. The unique properties of nano-sized DNA constructs can be exploited to develop programmable materials...

Dynamic DNA nanotechnology using strand-displacement reactions.

The specificity and predictability of Watson-Crick base pairing make DNA a powerful and versatile material for engineering at the nanoscale. This has enabled the construction of a diverse and rapidly growing set of DNA nanostructures and nanodevices through the programmed hybridization of complementary strands. Although it had initially focused on the self-assembly of static structures, DNA nan...
