Název v původním jazyce

Cholesterol conjugated oligonucleotide and LNA: A comparison of cellular and nuclear uptake by Hep2 cells enhanced by Streptolysin-O

Popis výsledku v původním jazyce

Antisense and antigene oligonucleotides (ONs) are attractive drugs for gene therapy, but major limiting factors for their routine use are inefficient cellular uptake and low accessibility to the target sites. Adding various lipophilic conjugates to the ON improves intracellular delivery as has been previously reported. We studied the cellular delivery of various ON modifications, as well as their cytosolic and nuclear distribution in mammalian Hep2-EGFP-NLS cell line. We compared uptake efficacy of ON and LNA, both conjugated with cholesterol at the 5´ end. All ONs were 3´ labeled with fluorescent Cy5 dye. We made a comparison of the ONs uptake efficacy and the kinetics, both adding ONs to the culture medium, and using streptolysin-O (SL-O) permeabilization.
