OLIGONUCLEOTIDE DUPLEXES COMPRISING DNA-LIKE AND RNA-LIKE NUCLEOTIDES AND USES THEREOF

摘要

Novel oligonucleotide pairs which can form a duplex comprising one or more DNA-like nucleotides (e.g., 2′-substituted arabinonucleotides (ANA)); in combination with one or more RNA-like nucleotides (e.g., 2′-substituted ribonucleotides (RNA) and/or locked nucleic acid nucleotides (LNA)), are disclosed. The use of such oligonucleotide duplexes, such as for silencing the expression of a nucleic acid or gene of interest using small interfering RNA (siRNA) technologies, is also disclosed.
