项目摘要
PROJECT SUMMARY/ABSTRACT
Noncoding ribonucleic acid molecules called microRNAs (miRNAs) have recently emerged as important
biological regulators that suppress the expression of target genes via messenger RNA degradation or
translational repression. Since miRNAs can regulate gene expression, there is intense interest in utilizing these
molecules as tools to halt disease progression. Unfortunately, naked miRNAs are not suitable for clinical use
due to their poor stability, limited circulation half-‐‑life, and inability to enter cells. Accordingly, researchers
have begun to incorporate miRNAs into nanocarriers to facilitate their in vivo delivery. While some progress
has been made, there is substantial room for improvement, evidenced by the fact that only a single miRNA
nanocarrier has entered clinical trials. This lack of clinical translation indicates there is an urgent need for
mechanistic studies to elucidate the underlying principles that dictate the interactions between miRNA
nanocarriers and biological systems. We aim to address this need by capitalizing on our unique expertise in
nanoparticle design, which includes experience with both miRNA nanocarriers and targeted nanoparticle
systems. More specifically, we will elucidate how the physical and chemical properties of miRNA nanocarriers
influence five specific outcomes related to the challenges associated with in vivo miRNA delivery. These
include: stability and nuclease resistance, cell uptake and intracellular trafficking, gene regulation potency,
biodistribution, and ability to halt progression of diseases including breast cancer and osteoporosis. By
studying these five outcomes, we can increase understanding of the effects of miRNA nanocarriers on the
body, as well as the effects of the body on miRNA nanocarriers. This will enable us to establish a set of design
rules that govern the interactions between miRNA nanocarriers and biological systems and which can be
applied in the de novo synthesis of miRNA nanocarriers to maximize their site-‐‑specific delivery and efficacy.
Over the next five years we will focus explicitly on studying how incorporating targeting agents into miRNA
nanocarriers influences the five aforementioned outcomes. By comparing different types of targeting agents
(e.g., antibodies or proteins) we can increase knowledge of the mechanisms of nanoparticle interactions with
cell surface receptors and the impact they have on signal transduction. We hypothesize that targeting agents
can not only promote cell binding, but also manipulate signaling cascades via receptor-‐‑mediated processes. If
this hypothesis is correct, combining miRNA delivery with targeting agent-‐‑mediated signal cascade
manipulation may have synergistic effects on diseased cells. Importantly, in the future we will expand our
studies to investigate other features of miRNA nanocarriers such as size, shape, and stiffness. This will enable
us to distinguish how the nanocarrier itself influences various biological outcomes. This important information
will enable creation of accurate design rules that will facilitate more efficient clinical translation of new miRNA
nanocarriers for disease intervention.
