Micro RNA therapy is based on the premise that
A. miRNA molecules function to regulate gene expression, usually by initiating transcription; an over-production of miRNA can be replaced thereby promoting necessary protein production. B. miRNA molecules function to regulate gene expression, usually by promoting translation; a non-functional miRNA can be repaired thereby reducing unwanted protein production. C. miRNA molecules function to regulate protein production, usually by inhibiting translation; a hyperactive miRNA can be replaced thereby reducing unwanted proteins. D. miRNA molecules function to regulate gene expression, usually by inhibiting transcription; a non-functional miRNA can be replaced thereby reducing unwanted protein production.
