Oligonucleotide-based therapy is highly promising because they target levels of corresponding downstream proteins and regulate multiple cellular pathways. However, clinical application of oligonucleotide-based therapy is limited due to the stability of oligonucleotide in biological environment and lack of efficient delivery system to target tissue. Chapter 2 established a novel lipid-based nanoparticle system for targeted delivery of oligonucleotide-based therapy selectively to hepatocellular carcinoma (HCC) cells. The novelty of this delivery system was the combination of a synthesized ligand for liver-targeted delivery and a hydrophobic peptide for improved endosomal escape. The in vitro and in vivo evaluations of this delivery system showed favorable physiochemical properties, improved delivery efficiency and superiority over commercial delivery agent, suggesting its potential application in oligonucleotide-based therapy in liver disease. Chemotherapy is one of the major categories for current cancer treatments to prolong life or reduce symptoms. Conventional chemotherapeutic drugs in cancer therapies are often act by killing highly dividing cells, which also harm normal cells and cause severe side effects to normal organs. In order to maximize the treatment efficacy while minimizing side effects, the development of efficient delivery systems is urgently needed. In Chapter 3, a liver-targeted lipid-based delivery system was developed and evaluated for doxorubicin delivery (Lac-L-DOX). This Lac-L-DOX exhibited preferential uptake by targeted tissue and enhanced therapeutic efficacy than non-targeted vehicles. In Chapter 4, a novel lyophilized liposomal formulation of bortezomib was successfully designed and developed. This formulation exhibited excellent stability and improved efficacy. To the best of our knowledge, this is the first study of formulating bortezomib into lipid-based nanoparticles to greatly enhance the therapeutic efficacy and reduce non-specific tissue toxicity. In conclusion, the development of lipid-based nanoparticles for therapeutic oligonucleotide-based therapy and chemotherapy delivery would provide an insight to novel therapeutic strategy for the efficient management of cancer treatments. 2014 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1417025932 http://rave.ohiolink.edu/etdc/view?acc_num=osu1417025932 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
