Adenosine News and Research

RSS

Adenosine is a nucleoside composed of a molecule of adenine attached to a ribose sugar molecule (ribofuranose) moiety via a ß-N9-glycosidic bond.

New high-throughput assay could help development of anti-COVID-19 drugs

In a recent study, researchers develop a new high-throughput assay that allows for rapid screening of potential inhibitors.

Researchers detect two types of RNA base modifications simultaneously using a quantum sequencer

After a gene is transcribed into RNA, modifications can occur to the subunits or "bases" that make up the RNA molecule, which can affect its structure and function. The study of these changes is known as "epitranscriptomics." These base modifications can occur to most types of RNA molecules, including microRNAs.

R37 MERIT Award supports innovative ovarian cancer research

One of the most impactful advancements during the past decade in treating ovarian cancer is the use of PARP inhibitors (short for poly adenosine diphosphate-ribose polymerase). PARP inhibitors are a type of cancer drug that blocks the PARP enzyme from helping to repair DNA damage in cancer cells.

Newly discovered cell type makes survivors of sepsis more vulnerable to infections

Sepsis is the leading cause of death in Brazil's intensive care units (ICUs). Among patients who progress to the severe form of the disease, 40% die, and the survivors often suffer from cardiovascular and neurological complications, as well as a significant decline in immunity lasting for years after they are discharged from hospital.

Antiviral activity of lipid-modified remdesivir in comparison to common remdesivir

In new research, scientists evaluated the broad-spectrum antiviral activity of ODBG-P-RVn, an orally available, lipid-modified monophosphate prodrug of the remdesivir parent nucleoside (GS-441524) against viruses that cause diseases of human public health concern, including SARS-CoV-2.

New live cell models lay the groundwork for studies into mitochondrial diseases

The mitochondrion has garnered quite the reputation for its role as the "powerhouse of the cell." These tiny, but mighty organelles play various life-sustaining roles, from powering our own cells and organs to fueling chemical and biological processes.

Study explores the effects of SARS-CoV-2 (and other betacoronaviruses) on cellular mRNA processing

A new study has been released on the bioRxiv* preprint server, which deals with a comprehensive survey on alternative splicing concerning SARS-CoV-2 infection. This study has also included two other betacoronavirurses (SARS-CoV and MERS), a control set of unrelated viruses, and a bacterium, namely, Streptococcus pneumonia. The study findings suggest that several cellular parameters are affected owing to a betacoronavirus infection, which in turn affects some genes and invariably various biological functions.

New class of compounds can stop the reproduction of coronavirus

A human genetic mechanism hijacked by SARS-CoV-2, the coronavirus behind the COVID-19 pandemic, to help it spread also makes it vulnerable to a new class of drug candidates, a new study finds.

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).
