Oligonucleotides are short sequences of nucleotides (RNA or DNA), typically with twenty or fewer bases. Automated synthesizers allow the synthesis of oligonucleotides up to 160 to 200 bases.

Study involving a rat model offers potential treatment for Alexander disease

Alexander disease is a progressive and rare neurological disorder with no cure or standard course of treatment. But a new study led by researchers at the University of Wisconsin–Madison involving a rat model of the disease offers a potential treatment for the typically fatal condition.

Nucleoside modifications suppress the potential of RNA to activate dendritic cells

A new paper shows that human TLR3, TLR7, and TLR8 receptors are activated with naturally occurring RNA, but this is eliminated once modified nucleosides such as m5C, m6A, m5U s2U, or pseudouridine are incorporated.

Researchers find a way to turn SARS-CoV-2’s virulence mechanism against itself

A recent study, currently available on the bioRxiv* preprint server, reveals that a specific region of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be targeted by antisense oligonucleotides to potently inhibit viral replication, and consequently the development of coronavirus disease (COVID-19).

Antisense oligonucleotides engineered to inhibit SARS-CoV-2

In a paper recently uploaded to the bioRxiv* preprint server, structure-based ASOs are developed against SARS-CoV-2, intended to bond with RNA in its structured in situ form, rather than the more rarely encountered linear section, achieving greater affinity and specificity than linear ASOs, and demonstrating inhibition of virus replication in human cells.

Innovative therapeutic platform for blood-to-brain delivery of antisense oligonucleotide therapy

Antisense oligonucleotide (ASO) therapy has the potential to ameliorate many neurodegenerative diseases at the genetic level to suppress the production of harmful proteins or non-coding RNAs.

Potential new treatment for mast cell cancers reduces tumor size and prevents organ infiltration

A potential new treatment for mast cell cancers reduces the number of mast cells by "mutating" the messenger RNA (mRNA) before it can deliver instructions for manufacturing the gene responsible for cell proliferation.

Researchers discover titanium oxide nanoparticle that recognizes SARS-CoV-2’s non-structural protein 1

A pioneering study reports on the interaction of a tailored titanium oxide nanoparticle (NP) with the full-length SARS-CoV-2 non-structural protein 1 (nsp1). This should be of value in developing new therapeutic tools against coronaviruses that act by targeting their proteins. It could also help map the structure of activated proteins.

Polyuridine sequence of mouse coronavirus can be targeted to prevent host cell death

A new study reports the use of a modified deoxyribonucleic acid (DNA) oligonucleotide that has a 3’ polyadenine (polyA) tail to bind to the 5’-polyU tract in the mouse coronavirus (MHV-A59). Treatment of mouse cells infected with MHV-A59 with this molecule led to a marked reduction in cell deaths.

Could novel biosensors facilitate SARS-CoV-2 antiviral drug research?

An intriguing new study presents a novel approach to biosensor-based evaluation of promising drugs that could inhibit the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via its 3C-like protease (3CLpro), a viral protease.

SARS-CoV-2 interacts with unusual RNA structures in human cells

The study, published in the journal Nucleic Acids Research, demonstrated that G4 ligands, the chemical that binds with G4s, prevent this interaction. The results could pave the way for developing inhibitors of these interactions as potential antiviral compounds.

Viral phosphoesterases (including in CoVs) can restrict antiviral innate immunity

An interesting new study describes the activities of a family of viral enzymes called two-histidine-phosphoesterases (2H-PEs), found in coronaviruses (CoVs) and rotaviruses, as well as a mammalian A-kinase anchoring protein enzyme, AKAP7, that shares the same function. Together called 2’,5’-PEs, these enzymes all break down 2’,5’-oligoadenylate compounds that activate the antiviral enzyme ribonuclease L (RNase L).
