Arginine methylation important in SARS-CoV-2 viral replication

Researchers show that methylation of arginine in the virus nucleocapsid protein controls the protein's functions and plays a role in the life cycle of the SARS-CoV-2 virus.

New antibiotic compound can effectively clear multi-drug resistant gonorrhea in animals

A new antibiotic compound clears infection of multi-drug resistant gonorrhea in mice in a single oral dose, according to a new study led by researchers at Penn State and Emory University.

SARS-CoV-2 is extremely sensitive to type I IFN pre-treatment, study finds

Researchers have found that SARS-CoV-2 is extremely sensitive to type I IFN pre-treatment. Therefore, strategies such as focusing on limiting the production of IFN, rather than its function, could restrict the mechanism of SARS-CoV-2 that increases its viral load with delayed or absent symptoms.

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.

Identification of neutralizing IFNL3 autoantibodies in severe COVID-19 cases

Scientists have recently developed a novel alternative molecular display technology called Molecular Indexing of Proteins by Self Assembly (MIPSA). Their research explains how this technology overcomes the critical disadvantages of PLATO and other full-length protein array technologies.

Researchers explore early stages of ribosome formation to identify new targets for antibiotics

Ribosome formation is viewed as a promising potential target for new antibacterial agents. Researchers from Charité - Universitätsmedizin Berlin have gained new insights into this multifaceted process.

COVID-19 may alter host proteins to cause autoimmunity

To better understand the transient and chronic autoimmune symptoms caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, researchers from Memorial Sloan Kettering Cancer Center, Guizhou Medical University, and biotech company Curandis embarked on an endeavor to establish a comprehensive autoantigenome for COVID19.

After billions of dollars and dozens of wartime declarations, why are vaccines still in short supply?

The U.S. government has invested billions of dollars in manufacturing, used a wartime act dozens of times to boost supplies and yet there's still not enough covid vaccine on the way to meet demand — or even the government's own goals for national immunization.

Study reveals mechanism for translation of maternally inherited mitochondrial genome

An international collaboration among researchers from Finland, Sweden, UK and the USA has captured ribosomes translating messenger RNA expressed from the maternally inherited mitochondrial genome.

Chronic hypoxia upregulates RNA polymerase I, alters methylation on ribosomal RNAs

Hypoxia -- where a tissue is deprived of an adequate supply of oxygen -- is a feature inside solid cancer tumors that renders them highly invasive and resistant to treatment. Study of how cells adapt to this critical stressor, by altering their metabolism to survive in a low-oxygen environment, is important to better understand tumor growth and spread.

Codon frequency optimization shows SARS-CoV-2 antiviral potential

A study conducted by researchers in the US has revealed that optimization of codon for bacterial expression causes the production of an inactive enzyme non-structural protein 12 (Nsp12), a catalytic subunit of RNA-dependent RNA polymerase of SARS-CoV-2.

Study shows that single water molecule may cause antibiotic resistance

New high-resolution structures of the bacterial ribosome determined by researchers at the University of Illinois Chicago show that a single water molecule may be the cause -; and possible solution -; of antibiotic resistance.

The structure dynamics of the SARS-CoV-2 genome in cells, cell lysates and virions

Now, a new preprint research paper posted to the bioRxiv server describes the structures observed during the lifecycle of the RNA virus in terms of both canonical and alternative structures, RNA-RNA interactions, and replication regulation.

Study sheds new light on immune system interactions with cancer

Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments.

POSTECH researchers solve the enigma to treating neurological diseases

Neurological diseases of the brain such as dementia, autism and schizophrenia are now a growing social problem. Nevertheless, studies on their definitive cause are still insufficient.

SARS-CoV-2 launches multipronged attack against host cell protein synthesis, study finds

An interesting new study throws a flood of light on how SARS-CoV-2 accomplishes its mission to infect and replicate within host cells while evading the host immune response.

Antimalarials could disrupt SARS-CoV-2’s Nsp1 translation termination

A research team from the Engelhardt Institute of Molecular Biology in Russia have shown that Nsp1 – a non-structured protein present in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen – stimulates translation termination in the stop codon recognition stage. Studying and developing drugs that compete with Nsp1 for binding with the termination complex could therefore be a potential strategy for fighting against coronavirus disease 2019 (COVID-19).

Translational study within SARS-CoV-2 infected cells opens up new therapeutic avenues

A recent study published on the preprint server bioRxiv in October 2020 shows what the protein translation process looks like in specific terms. In doing so, the study has provided new insights that might prove helpful in developing new therapies for COVID-19 patients.

Study may help develop effective drugs against COVID-19

Scientists at the University of Cambridge, in collaboration with Justus-Liebig University, Germany, have uncovered how the genome of SARS-CoV-2 - the coronavirus that causes COVID-19 - uses genome origami to infect and replicate successfully inside host cells.

Rapid generation of divergent synthetic antibodies against SARS-CoV-2 in a cell-free engineering platform

In a groundbreaking bioRxiv paper, a research group from the Massachusetts Institute of Technology (MIT), Harvard University and Howard Hughes Medical Institute in the US engineered antibodies against the receptor-binding domain (RBD) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein by using a novel approach. In doing so, they also identified more than 800 predicted binder families.
