Disclosed herein are short interfering nucleic acid (siNA) molecules comprising modified nucleotides and uses thereof. The siNA molecules may be double stranded and comprise modified nucleotides selected from 2'-O-methyl nucleotides and 2'-fluoro nucleotides. Further disclosed herein are siNA molecules comprising additional modification including a phosphorylation blocker, conjugated moiety, or 5'-stabilized end cap. The siNA molecules may reduce or inhibit the production of hydroxysteroid dehydrogenase.
The -L-Threofuranosyl-(3′→2′)-oligonucleotide System (‘TNA'): Synthesis and Pairing Properties
α-L-Threofuranosyl-(3′2′)-oligonucleotides (‘TNA') are part of a systematic experimental inquiry into the base-pairing properties of potentially natural nucleic acid alternatives taken from RNA's close structural neighborhood. TNA is an efficient Watson-Crick base-pairing system and has the capability of informational cross-pairing with both RNA and DNA. This property, together with the system's constitutional
