Because the cell machinery cannot recognize the unnatural backbone of PNA, it fails to break down this structure, making PNAs very stable, long-lived molecules. To enable the PNAs to enter cells, Ly modified the PNA backbone so that ...Wolfgang Heckl awarded Descartes Prize for Science Communication

"Since we know FAK to be highly expressed in the nerve tissue during brain development, this study suggests that phosphorylation of tyrosine 576 may be critical for axon and dendrite outgrowth," Dr. He reported.
