Popis: Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and its incidence continues to increase. Although there are approved therapies for HCC, the prognosis remains poor. The 5-year survival rate is < 5%. Nucleic acid-based therapeutics such as RNAi may improve patient outcome. Nevertheless, target identification/validation for HCC and delivery of siRNA are major challenges facing the development of HCC-specific RNAi based therapeutics. To enable target validation in vivo using RNAi, we have developed nanolipid siRNA formulations for the in vivo delivery of siRNA to orthotopic tumors. PK/PD studies in model systems demonstrate that up to 80% knockdown of target protein is achievable within tumors and that significant knockdown persists for at least 10 days following a single dose of formulated siRNA. Efficacy studies using similar formulations of siRNAs against potential HCC tumor targets, including mTOR, will be presented. Citation Format: {Authors}. {Abstract title} [abstract].
