タイトル RNA Oncological Therapeutics: Intracellular Hairpin RNA Assembly Enables MicroRNA-Triggered Anticancer Functionality.
ジャーナル J Am Chem Soc
Abstract RNA therapeutics are of global interest because of their versatility in targeting a variety of intracellular and extracellular biomolecules. In that context, long double-stranded RNA (dsRNA) has been studied as an antitumor agent that activates the immune response. However, its performance is constrained by poor cancer selectivity and cell-penetration ability. Here, we designed and synthesized an oncolytic RNA hairpin pair (oHP) that was selectively cytotoxic toward cancer cells expressing abundant oncogenic microRNA-21 (miR-21). Although the structure of each hairpin RNA was thermodynamically metastable, catalytic miR-21 input triggered it to open to generate a long nicked dsRNA. We demonstrated that oHP functioned as a cytotoxic amplifier of information in the presence of miR-21 in various cancer cells and tumor-bearing mice. This work represents the first example of the use of short RNA molecules as build-up-type anticancer agents that are triggered by an oncogenic miRNA.
