Preparation and Evaluation of A Novel Liposomal Nano-Formulation in Metastatic Cancer Treatment Studies
Journal Title: Cell Journal(Yakhteh) - Year 2019, Vol 21, Issue 2
Abstract
Objective: Today, in clinical trials, we suffer from the lack of effective methods with minimal side effects to deliver medication. Thus, efforts to identify better conditions for delivery of biomedical drugs seem necessary. The purpose of this study was to design a new liposomal formula for transportation of microRNA in osteosarcoma. Materials and Methods: In this experimental study, several liposomal formulations were synthesized. Physical and chemical parameters, including size, zeta potential, polydispersity index, long-term stability of the liposomal-microRNA complex and the amount of miR-143 loading in liposome based nano-vesicles were optimized using different techniques. Similarly, the effect of free and encapsulated microRNA toxicity were investigated and compared in a human bone osteosarcoma cell line, named SaOs-2. Results: In this study, we could produce a novel and optimized formulation of cationic PEGylated liposomal microRNA for gene delivery. The present synthesized microRNA lipoplex system was non-agglomerated. The system remained stable after four months and miR-143 leakage was not observed by performing gel electrophoresis. The microRNA lipoplex could enhance conduction of the loaded miR-143, and it also showed good biocompatibility to the healthy cells. Conclusion: The PEGylated microRNA lipoplex system had a high potential for the systematic migration of miR-143 and it could improve intracellular stability of the released microRNA.
