RT Dissertation/Thesis T1 Polysaccharide functionalised span nanoparticles as gene delivery systems. Application in the treatment of colorectal liver metastasis A1 Fernández Piñeiro, Inés K1 Nanoparticles K1 Gene therapy K1 Polysaccharides K1 microRNA AB The main objective of this work has been the design of a new polysaccharide functionalised nanosystem as a non-viral microRNA vector for the treatment of liver metastasis from colorectal cancer. For this purpose, we modified our previously developed span nanoparticles using polysaccharides with endothelial targeting properties and studied their ability to act as gene delivery systems. Finally, we provide an in vivo proof-of-concept of the clinical potential of these nanoparticles as a novel microRNA-based therapeutic strategy for cancer treatment.
