title: Calcium liberates PNAs from endosomes.
abstract: Many peptides are reported to enhance cellular uptake of peptide nucleic acids and other macromolecules. Cellular uptake, however, is not synonymous with cellular activity. In this issue of Chemistry and Biology, Nielsen and colleagues examine the traffic of PNAs and investigate protocols for improving recognition of target mRNA inside cells.
