SARS-CoV-2 mutated spike proteins show variations in cell entry

A new study by Japanese scientists published on the preprint server bioRxiv* in June 2020 shows that the D614g mutation in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein can enhance the infectivity of the virus while leaving it vulnerable to neutralization by antibodies.

Novel ACE2-antibody fusion molecules show anti-SARS-CoV-2 activity

Now, in a new study published on the preprint server, bioRxiv researchers in the U.S. investigated a soluble version of ACE2 for SARS-CoV-2 viral neutralization activity.

How antibodies neutralize SARS-CoV-2 in convalescent patients

A new study by researchers from the United Kingdom and Taiwan and published on the preprint server bioRxiv in June 2020 describes the structural basis for the neutralizing effect of the SARS-CoV-2 antibody on the virus. This also indicates a possible therapeutic molecule by identifying its binding epitope as possibly a major neutralizing site.

Exercise has profound protective effect in mouse models of Friedreich's ataxia

A top exercise researcher at the University of Virginia School of Medicine is urging clinical trials of exercise in patients with Friedreich's ataxia after finding that physical activity has a "profound" protective effect in mouse models of the debilitating genetic disease.

Early genetic rescue may be a potential therapy in autism spectrum disorder

A mouse study by Craig Powell, M.D., Ph.D., and colleagues suggests that early genetic rescue may be a potential therapy in autism spectrum disorder or ASD.

Micro-dystrophin gene therapy can improve outcomes in children with Duchenne muscular dystrophy

Researchers from Nationwide Children's Hospital have published in JAMA Neurology results from the first four patients treated in the first clinical trial of systemic delivery of micro-dystrophin gene therapy in children with Duchenne muscular dystrophy (DMD) - and initial findings suggest that the therapy can provide functional improvement that is greater than that observed under the standard of care.

SARS-CoV-2 mutation reduces S1 shedding, increases infective potential

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the seventh coronavirus known to infect humans. SARS-CoV-2 emerged in the last month of 2019 in Wuhan, China, sparking off the ongoing COVID-19 pandemic. This virus enters the host cells through receptor binding and membrane fusion between the viral and host cell membrane.

Tracing coronavirus habitats with genomics

Now, a new study by researchers at the University of Ottawa and published on the preprint server bioRxiv in June 2020 reports the differences in genomes of viruses that are exposed to antiviral proteins vs. those that are not. This host-derived pressure on the virus to adapt may help devise newer ways to build an effective vaccine.

U.S. and European SARS CoV-2 mutation enhances transmission, increases infectivity

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is causing the COVID-19 pandemic across the world has undergone a genetic mutation in the density of functional spikes on the virus, says a new study. This has led the virus to become highly infectious and easily transmissible between humans.

Identifying early routes of SARS-CoV-2 introduction to Los Angeles

Researchers at Cedars-Sinai Medical Center, Los Angeles, have described for the first time, the likely sources of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) introduction to the Los Angeles community.

Dante Labs, Cambridge Cancer Genomics and Nonacus collaborate to provide precision oncology at scale

Dante Labs, Cambridge Cancer Genomics, and Nonacus, today announced that they have signed a collaboration agreement.

Glycans "lock and load" the SARS-CoV-2 spike protein for infection

A new study by scientists from the University of California San Diego, USA and Maynooth University, Ireland and published on the preprint server bioRxiv* in June 2020 reports preliminary results showing that the spike protein of the SARS-CoV-2, as well as its glycan coat, has “hitherto unseen functional and structural” properties. These may be useful in designing novel therapeutics to target this molecule.

Effect of human genes on severity and infectivity of SARS-CoV-2

Now, a new paper published on the preprint server medRxiv* reports the results of an analysis of the association between the genetic variants in the patients and the clinical progression of the disease. The study included 332 patients hospitalized with COVID-19 in a single-center, with widely varying laboratory and clinical features. There were 25, 12, and 17 patients with asymptomatic, mild, and critical disease.

Study reveals protein responsible for vulnerability in cancer cells

A new University of California, Irvine-led study reveals a protein responsible for genetic changes resulting in a variety of cancers, may also be the key to more effective, targeted cancer therapy.

MGH researchers identify key mechanism in X chromosome inactivation

Researchers at Massachusetts General Hospital have identified a key mechanism in X chromosome inactivation, a phenomenon that may hold clues that lead to treatments for certain rare congenital disorders.

Researchers question the mechanism of retinitis pigmentosa

Researchers who made a knock-in mouse-model of the genetic disorder retinitis pigmentosa 59, or RP59, expected to see retinal degeneration and retinal thinning. As reported in the journal Cells, they surprisingly found none, calling into question the commonly accepted -- though never proved -- mechanism for RP59.

Researchers use human stem cell models to analyze degeneration in glaucoma

More than 3 million Americans have glaucoma, a serious eye condition causing vision loss. Using human stem cell models, researchers at Indiana University School of Medicine found they could analyze deficits within cells damaged by glaucoma, with the potential to use this information to develop new strategies to slow the disease process.

German researchers recommend early screening and treatment for spinal muscular atrophy

The advent of therapeutic interventions for spinal muscular atrophy (SMA) has increased the importance of presymptomatic diagnosis and treatment. When to start treatment in children with less severe disease remains controversial.
