Could a mathematical application of information theory identify and predict SARS-CoV-2 mutations?

An interesting new study by researchers at the University of Portsmouth, UK, describes the use of a mathematical method to sequence genomes based on information theory. The method offers an alternative to clinical techniques, allowing mutations to be detected and possibly even predicted. In this way, it opens new research opportunities in bioinformatics and genetics.

SARS-CoV-2 NSP14 induces potent inflammation via NF-κB pathways, finds study

SARS-CoV-2 has a single-stranded RNA genome encoding both structural and non-structural proteins. Of these, the latter is known to play a variety of roles in viral replication and the assembly of new viral particles, as well as in suppressing cellular immune responses. A new study reports the activity of one such protein, the non-structural protein 14 (NSP14), which activates the inflammatory mediator NF-κB to trigger intense inflammation.

High-throughput system can regulate gene expression for treating sickle cell disease, beta thalassemia

St. Jude Children's Research Hospital scientists have developed an integrated, high-throughput system to better understand and possibly manipulate gene expression for treatment of disorders such as sickle cell disease and beta thalassemia. The research appears today in the journal Nature Genetics.

Unique system detects small changes in DNA structures

Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now.

Ebola virus's key protein uses molecular triggers in the human cell to change shape

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape - and biologists are taught that defined shape dictates the protein's destined function.

Inhibition of nsp14 methyltransferase as a potential antiviral target for SARS-CoV-2

Beyond vaccination, the broad-spectrum antiviral medication remdesivir has robust clinical evidence and is known as the best antiviral treatment to reduce severe COVID-19 infection in hospitalized patients. Research led by John F.X. Diffley of the Chromosome Replication Laboratory suggests a potential therapeutic target for treatment development is the viral RNA cap methyltransferases, essential for viral protein translation and immune evasion.

Screening for SARS-CoV-2 non-structural protein 14 inhibitors

In a paper recently uploaded to the preprint server bioRxiv* by Diffley et al. (April 8th, 2021), inhibitors of one essential SARS-CoV-2 non-structural protein are explored, with four compounds, in particular, identified as potential antiviral leads that exhibit synergistic effects with antiviral drug remdesivir.

Racial diversity and poverty may influence heart-failure morbidity and mortality

Race associates with the risk of death from end-stage heart failure. So, identifying the molecular determinants of that risk may help the pursuit of the novel diagnosis and prognosis of heart failure, and its therapy.

Natural selection and adaptation of SARS-CoV-2 in mammals

Researchers of the Hubei University of Medicine, China, have analyzed several mutations in different variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from mammal species that suggest natural selection and host adaptation are occurring in the virus.

Study shows how mutant huntingtin protein triggers brain cell death

In 1993, scientists discovered that a single mutated gene, HTT, caused Huntington's disease, raising high hopes for a quick cure. Yet today, there's still no approved treatment.

Kruppel-like factor 2 may be a major determinant of acute respiratory distress syndrome in COVID-19 patients

A study conducted at the University of Chicago, USA, has recently revealed that downregulation of an endothelial transcription factor, Kruppel-like factor 2, by SARS-CoV-2 is responsible for ARDS frequently observed in critically ill COVID-19 patients.

Huntington’s disease mutant gene affects brain and body growth in childhood

There is growing evidence to support the hypothesis that there is a neurodevelopmental component to the late-onset neurodegeneration occurring in the brain of huntingtin gene (HTT gene) mutation carriers, and that this increased susceptibility to brain cell death begins during childhood.

5-amino levulinic acid inhibits SARS-CoV-2 infection in vitro

Researchers tested 5-amino levulinic acid in vitro in human-derived cells and found it prevents severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Because it is safe and ubiquitous in plants and animals, it could be a potential drug against SARS-CoV-2.
