UK SARS-CoV-2 variant 40% more transmissible than previous strains

Researchers in Japan have estimated that the B.1.1.7 strain of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that recently emerged in England is 40% more transmissible than strains previously circulating in the country.

Study investigates how genetic variants contribute to increased risk of lung cancer

Lung cancer is the leading cause of cancer death in the U.S. for both men and women. While risk for this disease can be influenced by environmental and lifestyle factors like smoking, studies estimate that 18% of lung cancer cases are due to inherited genetic variants.

New Colombian SARS-CoV-2 lineage shares antibody-resistant mutations with other variants

Scientists in Colombia have identified a new highly divergent SARS-CoV-2 lineage with Spike substitutions L249S and E484K. These same mutations have convergently appeared in other mutant strains of the virus, most notably in variants of concern.

New study aims to develop alternative treatment for posterior eye diseases

Getting poked in the eye with a sharp object is a cringeworthy thought. However, many patients with posterior eye diseases -- back of the eye diseases such as macular degeneration or diabetic retinopathy -- undergo eye injections through the wall of the eye as a medical treatment on a regular basis.

SARS-CoV-2 Brazilian variant may potentially escape T cell-mediated host immune responses

A team of scientists from Brazil recently explored the abilities of the UK, South African, and Brazilian variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to evade host CD8+ T cell responses induced by natural infection or vaccination. The findings reveal reduced antigenic coverage for the P.2 Brazilian lineage, indicating its ability to evade SARS-CoV-2-induced T cell responses.

Backtracking occurs within SARS-CoV-2 replication-transcription complex

Researchers continue to achieve a better understanding of SARS-CoV-2, the virus behind the ongoing COVID-19 pandemic. One such effort has been reported in a new preprint on the bioRxiv server, dealing with the phenomenon of backtracking.

The role of RNA capping of SARS-CoV-2 in immunity evasion

The SARS-CoV-2 pathogen successfully uses multiple immune evasion mechanisms to achieve infection within its host. An intriguing new study describes one such process, which may help develop drugs to counteract the virus more effectively.

New SARS-CoV-2 lineage has spread across many Brazilian states

Researchers in Brazil have identified the emergence of a new lineage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Brazil that has spread across multiple states in the country.

Princeton researchers elucidate how hepatitis B virus establishes chronic infection

Researchers at Princeton have determined how five cellular proteins contribute to an essential step in the life cycle of hepatitis B virus (HBV).

Novel CRISPR-based gene editor developed to correct mutations that cause genetic disorders

A team of researchers from the Agency for Science, Technology and Research's (A*STAR) Genome Institute of Singapore have developed a CRISPR-based gene editor, C-to-G Base Editor (CGBE), to correct mutations that cause genetic disorders.

Genome-wide covariation analysis sheds light on the evolution of SARS-CoV-2

Researchers in the United States have computed genome-wide covariation within severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to investigate interactions that could be of considerable importance in the prevention, diagnosis, and treatment of coronavirus disease 2019 (COVID-19).

Researchers characterize antibody responses to COVID-19 mRNA-based vaccine

A team of scientists from the USA and Canada has recently characterized the antibodies developed against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in response to an mRNA-based coronavirus disease 2019 (COVID-19) vaccine.

RNA editing events influence gene expression and phenotypic manifestation

Combining computational mining of big data with experimental testing in the lab, researchers at Children's Hospital of Philadelphia (CHOP) have identified RNA editing events that influence gene expression and, in turn, the phenotypic manifestation of that expression.

Somatic gene mutations in brain cells could contribute to schizophrenia pathology

Schizophrenia is a neurodevelopmental disorder that disrupts brain activity producing hallucinations, delusions, and other cognitive disturbances. Researchers have long searched for genetic influences in the disease, but genetic mutations have been identified in only a small fraction--fewer than a quarter--of sequenced patients.

How can physicians distinguish between COVID-19 persistence and SARS-CoV-2 reinfection?

One of the most challenging tasks of physicians has been differentiating between persistent COVID-19 and SARS-CoV-2 reinfection. Recently, a team of researchers analyzed SARS-CoV-2 sequences from the publicly available reports on reinfection and persistence. They further characterized the markers of reinfecting sequences and studied the mutation rate in newly evolved persistent variants.

Study explains how the B.1.1.7 SARS-CoV-2 variant is more transmissible

New research led by Thushan I. de Silva from the University of Sheffield proposes that increases in subgenomic RNA (sgRNA) expression cause increased viral transmissibility and subsequent infection. They suggest the ORF9 protein, found in high amounts of sgRNA, could be regulating interferon responses.

Deep learning-based splice-AI can help predict the onset of Alzheimer's disease

Korea Brain Research Institute (KBRI, President Suh Pann-ghill) announced that the research team led by Dr. Jae-Yeol Joo discovered new cryptic splice variants and SNVs in PLCg1 gene of AD-specific models for the first time using Splice-AI.

COVID-19 CG tracks local SARS-CoV-2 mutations by geographical location

Genomic surveillance of acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has varied across countries. England's increased coronavirus sequencing helped it uncover the B.1.1.7 variant last fall. In contrast, countries such as the United States have reported little sequencing data.

Researchers develop new tool for predicting the effects of SARS-CoV-2 missense variants

A new study by a team of researchers in the UK and US describes the use of a computational tool that generates all possible single amino acid substitutions in SARS-CoV-2 and predicts their effects.

Study reveals information about risk genes in schizophrenia

Dr. Felix-Martin Werner, working at the Euro Academy Pößneck in Germany and Prof. Rafael Coveñas, working at the Institute of Neurosciences of Castilla and León, Salamanca in Spain, have been working on neurological and psychiatric disease for over ten years.
