01
Overview
microRNA replacement is a therapeutic strategy that aims to restore the function of endogenous microRNAs (miRNAs) that are lost or downregulated in disease states, particularly cancer. It involves the delivery of synthetic miRNA mimics or expression vectors to reinstate normal regulatory control over gene expression by targeting specific messenger RNAs (mRNAs).

02
Mechanism of action
Restores post-transcriptional regulation via RISC-mediated silencing of target mRNAs by synthetic miRNA mimics, leading to translational repression or mRNA degradation.
