Development of bis-locked nucleic acid (bisLNA) oligonucleotides for efficient invasion of supercoiled duplex DNA
In spite of the many developments in synthetic oligonucleotide (ON) chemistry and design, invasion into double-stranded DNA (DSI) under physiological salt and pH conditions remains a challenge. In this work, we provide a new ON tool based on locked nucleic acids (LNAs), designed for strand invasion into duplex DNA (DSI). We thus report on the development of a clamp type of LNA ON-bisLNA-with ca...
متن کاملSplice-switching efficiency and specificity for oligonucleotides with locked nucleic acid monomers.
The use of antisense oligonucleotides to modulate splicing patterns has gained increasing attention as a therapeutic platform and, hence, the mechanisms of splice-switching oligonucleotides are of interest. Cells expressing luciferase pre-mRNA interrupted by an aberrantly spliced beta-globin intron, HeLa pLuc705, were used to monitor the splice-switching activity of modified oligonucleotides by...
متن کاملDesign and characterization of decoy oligonucleotides containing locked nucleic acids.
Transfection of cis-element double-stranded oligonucleotides, referred to as decoy ODNs, has been reported to be a powerful tool that provides a new class of antigene strategies for gene therapy. However, one of the major limitations of the decoy approach is the rapid degradation of phosphodiester oligonucleotides by intracellular nucleases. To date, several DNA analogs have been employed to ov...
متن کاملDesign of antisense oligonucleotides stabilized by locked nucleic acids.
The design of antisense oligonucleotides containing locked nucleic acids (LNA) was optimized and compared to intensively studied DNA oligonucleotides, phosphorothioates and 2'-O-methyl gapmers. In contradiction to the literature, a stretch of seven or eight DNA monomers in the center of a chimeric DNA/LNA oligonucleotide is necessary for full activation of RNase H to cleave the target RNA. For ...
متن کاملLocked nucleic acid molecular beacons.
A novel LNA-MB (molecular beacon based on locked nucleic acid bases) has been designed and investigated. It exhibits very high melting temperature and is thermally stable, shows superior single base mismatch discrimination capability, and is stable against digestion by nuclease and has no binding with single-stranded DNA binding proteins. The LNA-MB will be widely useful in a variety of areas, ...
