Protein transduction therapy is a promising alternative to gene therapy, but has not previously been investigated for osteosarcoma. We here demonstrate efficient growth inhibition of human osteosarcoma cells using a p53 peptide. Our result suggests that protein transduction therapy has significant potential as a novel therapeutic approach for osteosarcoma.

Keywords: Osteosarcoma; nuclear localization signal; p53 peptide; poly arginine; protein transduction domain; protein transduction therapy

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
