Researchers describe a novel role for hnRNP E1 protein in binding DNA in the nucleus

Cancer is a devastating disease and is the second leading cause of death in the U.S. One of the hallmarks of cancer is genomic instability, or the tendency to accumulate mutations and damage to the DNA that leads to genome alterations during cell division.

Small molecule drug can attenuate the triggers of neuroinflammation, preclinical study shows

Neuroinflammation can worsen outcomes in stroke, traumatic brain injury, or spinal cord injury, as well as accelerate neurodegenerative diseases like ALS, Parkinson's, or Alzheimer's. This suggests that limiting neuroinflammation may represent a promising new approach to treat neurological diseases and neuropathic pain that are driven by neuroinflammation.

Researchers decipher genetic mechanisms governing the speed of protein synthesis

In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then translated into protein with the help of ribosomes, small machines capable of decoding messenger RNA to synthesise the appropriate proteins.

Study uses computational modeling of coronavirus spike proteins to examine dynamics responsible for immunogenicity and immune escape

A new study published on the bioRxiv* preprint server focused on the development of dynamic computational models for a large subset of S proteins of SARS-CoV, MERS-CoV, and SARS-CoV-2.

Scientists identify a potent neutralizing nanobody against SARS-CoV-1

In a recently published article in the journal Virologica Sinica, scientists have described the development and validation of a potent nanobody that targets the receptor-binding domain (RBD) of severe acute respiratory syndrome coronavirus (SARS-CoV). The nanobody efficiently and specifically blocks the interaction between RBD and angiotensin-converting enzyme 2 (ACE2) and neutralizes the virus.

VPS29 gene facilitates coronavirus cell entry

In a research paper recently uploaded to the bioRxiv* preprint server by Poston et al. (August 8th, 2021), common host factors amongst several zoonotic pathogens are explored by CRISPR-Cas9 screening in human lung cells, focusing in particular on the betacoronavirus genus.

Cardioprotective role of HIF1α in COVID-19 patients

The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first emerged in Wuhan, China, in late December 2019, has quickly become the most urgent issue facing scientists worldwide. It has been reported that the respiratory infection causes cardiac dysfunction in 25-55% patients, including hospitalized patients and non-critical patients.

Vaccinia-based COVID-19 vaccines confer immunity in hamster model

In a paper recently uploaded to the preprint server bioRxiv* by Kulkarni et al. (August 3, 2021), the potential of vaccinia virus-based vaccines expressing the full-length SARS-CoV-2 spike protein is examined in mice and Syrian hamsters. The findings report that the vaccine generates high titers of neutralizing antibodies with good activity towards SARS-CoV-2 variants of concern.

Researchers discover titanium oxide nanoparticle that recognizes SARS-CoV-2’s non-structural protein 1

A pioneering study reports on the interaction of a tailored titanium oxide nanoparticle (NP) with the full-length SARS-CoV-2 non-structural protein 1 (nsp1). This should be of value in developing new therapeutic tools against coronaviruses that act by targeting their proteins. It could also help map the structure of activated proteins.
