  • Publication number: 20210023239
    Abstract: The present invention relates to oligonucleotide carriers for oligonucleotide delivery to a subject to provide gene therapy. More particularly, the present invention relates to therapeutic nanoparticles for microRNA (miRNA) delivery to a subject. More particularly, the present invention relates to therapeutic nanoparticles wherein miRNA is bindable to biocompatible nanoparticles using natural gene carrier Argonaute (AGO) protein or a variant thereof. Optionally, therapeutic nanoparticles of the present invention additionally contain targeting moieties for targeting therapeutic nanoparticles to cancer cells and/or chemotherapeutic agents. Optionally, biocompatible nanoparticles are trackable nanoparticles, such as superparamagnetic iron oxide nanoparticles (SPION), to provide multifunctional theranostics.
