Abstract

ABSTRACT: Introduction : Therapeutic oligonucleotides have emerged as a promising new class of drug that could silence undruggable targets; they can potentially treat metabolic liver diseases such as nonalcoholic fatty liver disease (NAFLD), hereditary hemochromatosis and alpha 1 antitrypsin deficiency. Areas covered : This article illuminates the mechanism of action of, and drug delivery approaches for therapeutic oligonucleotides such as antisense oligonucleotides (ASOs), short interfering RNAs (siRNAs), and MicroRNAs (miRs). We reveal why the liver is the ideal organ for therapeutic oligonucleotides, discuss its unique architecture, and shed light on those susceptible molecular targets that can be modulated. We also examine preclinical and clinical data on the utility of oligonucleotides in silencing the expression of genes responsible for metabolic liver diseases. Expert opinion : The liver has numerous susceptible molecular therapeutic targets; hence, metabolic liver diseases can be treated effectively by modulating these targets via novel therapeutic oligonucleotides. Undoubtedly, these exciting developments integrate well with precision medicine progress. Specific therapeutic oligonucleotides can be designed based on the exact underlying molecular mechanism of the disease. So, there is a justification for furthering the development of therapeutic oligonucleotides for metabolic liver diseases. Safety concerns such as immunogenicity and off-target effects will however require careful monitoring.
