Article Abstract

Antisense transcription is a widespread phenomenon in mammalian genomes, leading to production of RNAs molecules referred to as natural antisense transcripts (NATs). NATs apply diverse transcriptional and post-transcriptional regulatory mechanisms to carry out a wide variety of biological roles that are important for the normal functioning of living cells, but their dysfunctions can be associated with human diseases. In this review, we attempt to provide a molecular basis for the involvement of NATs in the etiology of human disorders such as cancers and neurodegenerative and cardiovascular diseases. We also discuss the pros and cons of oligonucleotide-based therapies targeted against NATs, and we comment on state-of-the-art progress in this promising area of clinical research.

Oligonucleotide therapeutics, including antisense oligonucleotides and small interfering RNA, offer promising avenues for modulating the expression of disease-associated proteins. However, challenges such as nuclease degradation, poor cellular uptake, and unspecific targeting hinder their application. To overcome these obstacles, spherical nucleic acids have emerged as versatile tools for nucleic acid delivery in biomedical applications.

2',4'-methylene bridged nucleic acid/locked nucleic acid (2',4'-BNA/LNA; LNA) is a modified nucleic acid that improves the function of antisense oligonucleotide therapeutics. In particular, LNA in the DNA strand increases its binding affinity for the target RNA. Predicting the binding affinities of LNA-containing antisense oligonucleotides and RNA duplexes is useful for designing antisense oligonucleotides.

Long non-coding RNA (lncRNA) plays important roles in animals and plants. In filamentous fungi, however, their biological function in infection stage has been poorly studied. Here, we investigated the landscape and regulation of lncRNA in the filamentous plant pathogenic fungus Botrytis cinerea by strand-specific RNA-seq of multiple infection stages.

The MIR-NAT MAPT-AS1 does not regulate Tau expression in human neurons.

PLoS One

January 2025

Neuroscience Discovery, Janssen Research & Development, Janssen Pharmaceutica, Beerse, Belgium.

The MAPT gene encodes Tau protein, a member of the large family of microtubule-associated proteins. Tau forms large insoluble aggregates that are toxic to neurons in several neurological disorders, and neurofibrillary Tau tangles represent a key pathological hallmark of Alzheimer's disease (AD) and other tauopathies. Lowering Tau expression levels constitutes a potential treatment for AD but the mechanisms that regulate Tau expression at the transcriptional or translational level are not well understood.
