Evaluation Of Muc1-Aptamer Functionalized Hybrid Nanoparticles For Targeted Delivery Of Mirna-29b To Nonsmall Cell Lung Cancer
MOLECULAR PHARMACEUTICS(2018)
摘要
The objective of this study was to evaluate the therapeutic efficacy and pharmacokinetic study of mucinl-aptamer functionalized miRNA-29b-loaded hybrid nanoparticles (MAFMILHNs) in lung tumor-bearing SCID mice. MAFMILHNs were manufactured using an isoelectric point based nano technology. They were then fully characterized for particle size, loading capacity, zeta potential, and encapsulation efficiency. The ability of MAFMILHNs to downregulate oncoprotein DNMT3B both at the cellular level and in vivo was monitored using Western blot, while the effect of the downregulation of DNMT3B on tumor growth was assessed using bioluminescence. Results indicate that the presence of MUC1-aptamer conjugated to the surface of the nanoparticles enhanced the selective delivery of miRNA-29b to tumor cells and tissues. Further, the downregulation of DNMT3B by MAFMILHNs resulted in the inhibition of tumor growth in mouse models.
