Abstract:
:We here describe a new strategy for the delivery of oligonucleotides to cells that is based on the use of a short peptide containing three functional units: a membrane-penetrating segment, a DNA-binding domain and a cell-localization sequence. The designed vector binds strongly to oligonucleotides and has membrane-perturbing abilities in vitro. This type of multi-functional device may be a powerful tool to achieve efficient delivery of genetic drugs in vivo.

杂志文章abstract::Cinnamomin is a type II ribosome-inactivating protein (RIP) and its A-chain (CTA) is a RNA N-glycosidase. It is observed that modification of tyrosine residues by N-acetylimidazole (N-AI) causes almost complete loss of CTA activity. Adenine partially protects tyrosine residues from modification by N-AI. It is proposed...
