Introdution: The aim of this study was to investigate the physico-chemical properties, surface charge and cytotoxicity of nanocomposite formulations for the design of lipid nano-systems with maximum loading for nucleic acids in bone marrow cancer.
Methods For this study, six types of liposomes with different compositions were synthesized using DPPC, cholesterol, DSPE-mPEG (2000) and DOTAP. Then, nanosystems were evaluated for particle size, surface charge, cytotoxicity and loading rate of miRNA in two MG-63 and SaOs2 cell lines, which are human cell bone marrow cell lines.
Results: All nano-systems were monodisperse. Among the systems, the F6 formula has the lowest toxicity and the highest load of miRNA-143, due to the presence of a suitable amount of DOTAP and PEG phospholipid in the liposome structure.
Conclusion: Liposomal formulation with a suitable percentage of DOTAP cationic phospholipid can be used as a successful carrier for the transport of miRNA in the gene therapy process for the treatment of various cancers, especially metastatic types.
