Intratumoral Administration of Anti-KITENIN shRNA-Loaded PEI-alt-PEG Nanoparticles Suppressed Colon Carcinoma Established Subcutaneously in Mice
Abstract:Biodegradable gene carrier, termed as PEI-alt-PEG, has been synthesized based on Michael addition reaction between lower Mw PEI and poly(ethylene glycol) (PEG) diacrylate and tested its potential of anti-metastatic cancer gene therapy by using anti-KITENIN short hairpin RNA. KITENIN is known to promote invasion of mouse colon adenocarcinoma in vivo. Intratumoral administration of anti-KITENIN shRNA-loaded PEI-alt-PEG nanoparticles has shown suppressed proliferlation and enhanced apoptosis signal in tumor compared to commercial available liposome, leading to delayed tumor growth.
