A summary of the article is shown below:

AIM: The overexpression of miRNA-21 correlates with the cisplatin (CIS) resistance in the ovarian cancers.METHODS: AS1411 antinucleolin aptamer-decorated PEGylated poly(lactic-co-glycolic acid) nanoparticles containing CIS (Ap-CIS-NPs) and anti-miR-21 (Ap-anti-miR-21-NPs) were prepared, physicochemically investigated and their cancer-targeting ability was confirmed. CIS-resistant A2780 cells (A2780 R) were infected with anti-miR-21 using Ap-anti-miR-21-NPs to decrease the drug resistance and sensitize the cells to CIS. Afterward, miR-21-inhibited cells were exposed to the Ap-CIS-NPs.RESULTS: Ap-anti-miR-21-NPs could infect the A2780 R cells mainly through nucleolin-mediated endocytosis and inhibit the endogenous miR-21. Targeted delivery of CIS using Ap-CIS-NPs into the miR-21-inhibited cells caused an enhanced mortality.CONCLUSION: The targeted delivery of chemotherapeutics to the oncomiR-inhibited cells may find a robust application in cancer chemo/gene therapy.
