LNA/DNA chimeric oligomers mimic RNA aptamers targeted to HIV TAR RNA.

"One of the major limitations of the use of phosphodiester oligonucleotides in cells is their rapid degradation by nucleases. To date, several chemical modifications have been employed to overcome this issue but insufficient efficacy and/or specificity have limited their in vivo usefulness.

"In this work conformationally restricted nucleotides, locked nucleic acid (LNA), were investigated to design nuclease resistant aptamers targeted against the HIV-1 TAR RNA," scientists in France report.

"LNA/DNA chimeras were synthesized from a shortened version of the...
