Abstract:
The majority of currently available drugs and tool compounds exhibit an inhibitory mechanism of action and there is a relative lack of pharmaceutical agents that are capable of increasing the activity of effectors or pathways for therapeutic benefit. Indeed, the upregulation of many genes, including tumour suppressors, growth factors, transcription factors and genes that are deficient in various genetic diseases, would be desired in specific situations. Recently, key roles for regulatory long non-coding RNAs (lncRNAs) in the regulation of gene expression have begun to emerge. lncRNAs can positively or negatively regulate gene expression and chromatin architecture. Here, we review the current understanding of the mechanisms of action of lncRNAs and their roles in disease, focusing on recent work in the design of inhibitors of the natural antisense transcript (NAT) class of lncRNAs, known as antagoNAT oligonucleotides, and the issues associated with their potential therapeutic application.
Insights
Pharmaceuticals often inhibit, but activating pathways is needed. Long non-coding RNAs (lncRNAs) offer a new target, with antagoNAT oligonucleotides showing therapeutic potential by modulating gene expression.
Area of Science:
- Molecular Biology
- Genetics
- Pharmacology
Background:
- Current drugs primarily inhibit biological processes, creating a need for agents that can enhance pathway activity.
- Upregulating specific genes, such as tumor suppressors or those deficient in genetic disorders, holds therapeutic promise.
- Regulatory long non-coding RNAs (lncRNAs) are emerging as critical regulators of gene expression and chromatin structure.
Purpose of the Study:
- To review the mechanisms by which lncRNAs regulate gene expression.
- To explore the role of lncRNAs in various diseases.
- To discuss the development and therapeutic potential of antagoNAT oligonucleotides targeting natural antisense transcripts (NATs).
Main Methods:
- Literature review of lncRNA mechanisms and roles in disease.
- Focus on antagoNAT oligonucleotides as inhibitors of NAT lncRNAs.
- Analysis of challenges in therapeutic applications of antagoNATs.
Main Results:
- lncRNAs can both activate and repress gene expression and influence chromatin architecture.
- NATs represent a class of lncRNAs amenable to inhibition by oligonucleotide-based therapeutics.
- The design and application of antagoNAT oligonucleotides are advancing.
Conclusions:
- lncRNAs are versatile regulators with significant implications for disease.
- AntagoNAT oligonucleotides offer a novel strategy for therapeutic intervention by targeting lncRNAs.
- Further research is needed to address challenges for the clinical translation of antagoNAT-based therapies.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
