Chimeric molecules consisting of peptide nucleic acid (PNA) and lactose have been synthesized to test the hypothesis that lactose moieties can promote cell-specific uptake of PNAs. We find that lactose modified PNAs rapidly enter liver-derived HepG2 cells while unmodified PNAs do not and that lactose modified PNAs can inhibit cellular telomerase.
