Control of intracellular delivery and inhibition of genetic expression by DNA-peptide conjugates.
Various types of DNA-peptide conjugates were synthesized by solid phase fragment condensation (SPFC). DNA-LNS (nuclear localizing signal) peptide conjugate was proved to be delivered and localized into cellular nucleus and exhibited higher antisense inhibitory effect against telomerase than antisense phosphorothioate DNA. In contrast, DNAzymes conjugated with NES (nuclear export signal) peptide was shown to be taken up and localized in cytoplasm. Inhibitory effect of the conjugate DNAzyme against BCR-ABL tyrosine kinase was evaluated to be more significant than the native DNAzyme.
