In vitro delivery of antisense oligonucleotides.
Oligonucleotides (ODNs) do not readily get access to their desired site (cytoplasm/nucleus) of action due to their high hydrophility and high molecular weight. Therefore enhancing components (carriers) are needed. Most widely used in vitro are cationic lipids (liposomes). Other systems include peptide conjugates or complexes, polymers and nanoparticles. We used cationic lipids and polymers, wit...
متن کاملIn Vitro Inhibition of Hepatitis C Virus by Antisense Oligonucleotides in PBMC Compared to Hepatoma Cells
AIM To assess the efficiency of phosphorothioate antisense oligodeoxynucleotide 1 (S-ODN1) on HCV translation inhibition in PBMC compared to hepatoma cells in vitro for the first time. MATERIALS AND METHODS The study included 34 treatment naive HCV patients. IRES domain III and IV sequence variations were tested in 45 clones from 9 HCV patients. PBMC of HCV positive patients were subjected to...
متن کاملSpecific inhibition of hepatitis B viral gene expression in vitro by targeted antisense oligonucleotides.
A 21-mer oligodeoxynucleotide complementary to the polyadenylation signal for human hepatitis B virus (HBV) was complexed to a soluble DNA-carrier system that is targetable to hepatocytes via asialoglycoprotein receptors present on those cells. A cell line, HepG2 (2.2.15) that possesses asialoglycoprotein receptors and is permanently transfected with hepatitis B virus (ayw subtype) was exposed ...
متن کاملMechanisms of the inhibition of reverse transcription by antisense oligonucleotides.
We have demonstrated that the synthesis of cDNA by avian myeloblastosis virus and Moloney murine leukemia virus reverse transcriptases can be prevented by oligonucleotides bound to the RNA template approximately 100 nucleotides remote from the 3' end of the primer. The RNA was truncated at the level of the antisense oligonucleotide-RNA duplex during the reverse transcription. The key role playe...
متن کاملInhibition of MDR1 gene expression by chimeric HNA antisense oligonucleotides.
Hexitol nucleic acids (HNAs) are nuclease resistant and provide strong hybridization to RNA. However, there is relatively little information on the biological properties of HNA antisense oligonucleotides. In this study, we compared the antisense effects of a chimeric HNA 'gapmer' oligonucleotide comprising a phosphorothioate central sequence flanked by 5' and 3' HNA sequences to conventional ph...
