Abstract
Mixmer oligonucleotides consisting of residues of both 2'-O-methylnucleosides (OMe) and locked nucleic acids (LNA) were designed targeting two stem-loops in the 5'-UTR of HIV-1 RNA, the transactivation response region (TAR), which is the site of binding of the Tat protein, and the SL3 loop, which is the primary packaging element that binds the Gag polyprotein. These oligonucleotides were found to inhibit syncitia formation dose- and sequence-dependently when delivered to HeLa T4 LTR beta-Gal cells and subsequently infected with HIV-1.
