Inhibition of HIV Replication by Cyclic and Hairpin PNAs Targeting the HIV-1 TAR RNA Loop
Human immunodeficiency virus-1 (HIV-1) replication and gene expression entails specific interaction of the viral protein Tat with its transactivation responsive element (TAR), to form a highly stable stem-bulge-loop structure. Previously, we described triphenylphosphonium (TPP) cation-based vectors that efficiently deliver nucleotide analogs (PNAs) into the cytoplasm of cells. In particular, we...
متن کاملInhibition of HIV-1 replication by eIF3f.
Viruses often use host machinery in unusual ways to execute different steps during their replication. To identify host factors critical for virus replication, we screened cDNA expression libraries for genes or gene fragments that could interfere with HIV-1 vector transduction. The DNA clone that most potently inhibited HIV-1 expression encoded the N-terminal 91 aa of the eukaryotic initiation f...
متن کاملPotent Inhibition of HIV-1 Reverse Transcriptase and Replication by Nonpseudoknot, “UCAA-motif” RNA Aptamers
RNA aptamers that bind the reverse transcriptase (RT) of human immunodeficiency virus (HIV) compete with nucleic acid primer/template for access to RT, inhibit RT enzymatic activity in vitro, and suppress viral replication when expressed in human cells. Numerous pseudoknot aptamers have been identified by sequence analysis, but relatively few have been confirmed experimentally. In this work, a ...
متن کاملInhibition of HIV-1 replication by RNA targeted against the LTR region.
OBJECTIVE The use of small RNA molecules able to effect gene inactivation has emerged as a powerful method of gene therapy. These small inhibitory RNAs are widely used for silencing malignant cellular and viral genes. We have assayed a series of inhibitory RNAs named catalytic antisense RNAs, consisting of a catalytic domain, hairpin or hammerhead ribozyme, and an antisense domain. The aim of t...
متن کاملInhibition of human immunodeficiency virus (HIV-1) replication by synthetic oligo-RNA derivatives.
Several synthetic 2'-O-methyl-RNA oligomers and their derivatives have been evaluated for inhibitory effect against HIV-induced cytopathic effect and expression of the virus specific antigen in cultured MT-4 cells. In this study, oligo(2'-O-methyl)ribonucleoside phosphorothioates showed a potent inhibitory activity with size dependency (25-mer showed it at 1 microM), but by contrast both 2'-O-m...
