Abstrakt: We synthesized phosphorothioated 2′-OMe RNAs containing PXA residues at the 5′-end of the strands (PXA-ORNs) for sequence-selective inhibition of gene expression of GFP in HeLa cells stably expressing GFP. The inhibitory efficiency is evaluated by measuring the fluorescent intensity of the expressed GFP. Cell-based assay revealed that under UV irradiation, PXA-ORNs greatly inhibit the gene expression of GFP (by as much as 60%).We synthesized phosphorothioated 2′-OMe RNAs containing PXA residues at the 5′-end of the strands (PXA-ORNs) for sequence-selective inhibition of gene expression of GFP in HeLa cells stably expressing GFP.
