| Research Abstract |
We developed novel tumor linegae-homing CPPs that are highly permeable to cancer cells according to their tumor linages. Random peptide library constructed by mRNA display technology was employed for isolating the CPPs encoded by novel aminoacid sequences which differ from conventional CPPs such as TAT,pAnt. Screening of over 40 CPPs of these,10 of them showed unique response that were efficiently incorporated to tumor cells following their tumor origins. These tumor linage-homing CPPs were efficiently incorporated to target cells in vivo and in vitro and are useful in peptide-based non-invasive medical technologies such as anti-cancer therapeutics and imaging.
