Yes, there are therapeutic applications of miRNAs. miRNA mimics and inhibitors are being developed to modulate miRNA activity in diseases. miRNA mimics are synthetic miRNAs that can restore the function of downregulated miRNAs, while miRNA inhibitors (antagomirs) are designed to inhibit the function of upregulated miRNAs. These therapeutic strategies are being investigated in preclinical and clinical settings for various diseases.
