First demonstration of COVID-19-like response by an essential virus encoded protein by SARS-CoV-2 in vivo

Researchers from collaborating universities in Virginia have recently utilized transgenic mice to explore the effects of SARS-CoV-2 on associated lung injury.

Muscles lose their smallest, most basic building blocks after stroke

After suffering a stroke, patients often are unable to use the arm on their affected side. Sometimes, they end up holding it close to their body, with the elbow flexed.

Researchers identify properties that enable proteins to remember and respond to pressure

A new rubber band stretches, but then snaps back into its original shape and size. Stretched again, it does the same. But what if the rubber band was made of a material that remembered how it had been stretched? Just as our bones strengthen in response to impact, medical implants or prosthetics composed of such a material could adjust to environmental pressures such as those encountered in strenuous exercise.

New wound gap closure mechanism may offer faster, better healing after injury or surgery

The observation of a previously undetected biological mechanism for closing gaps in living tissue improves basic understanding of the wound-healing process and may one day inform strategies to speed healing after surgery, according to a team of Penn State and Singapore researchers.

Newly identified protein could become a target for future cancer treatments

Researchers at the Francis Crick Institute have identified a protein that helps tumours evade the immune system and, in certain types of cancers, is linked to a poorer chance of survival. The protein could become a target for future cancer treatments.

AMSBIO's custom lentivectors for labeling organoids

AMSBIO have supplied custom lentivectors to Francesco Pampaloni and his team at the Buchmann Institute for Molecular Life Sciences in Frankfurt, Germany allowing them to visualize cell nuclei and F-actin cytoskeleton in their organoids.

Study examines impact of chemotherapy on mechanical properties of prostate cancer cells

Malignant tumor cells undergo mechanical deformation more easily than normal cells, allowing them to migrate throughout the body.

Antithrombotic endothelial dysfunction is prevented by Tie2 activation in severe COVID-19

Researchers from the US recently assessed if severe COVID-19 is linked to procoagulant dysfunction of the endothelium and changes in the Tie2-angiopoietin axis. They assessed circulating endothelial markers in a study cohort of 98 patients with mild, moderate, or severe COVID-19. This study is published on the medRxiv* preprint server.

Simple dietary supplement ameliorates schizophrenic traits in mice

A simple dietary supplement reduces behavioral symptoms in mice with a genetic mutation that causes schizophrenia.

Researchers provide ultrastructural details of SARS-CoV-2-infected respiratory epithelial cells

A team of scientists from the United Kingdom recently investigated the ultrastructural details of the attachment, entry, and budding processes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the human airway epithelium. They have used a highly differentiated air-liquid interface cultures of airway epithelium to thoroughly investigate the viral infection cycle. The study is currently available on the bioRxiv* preprint server.

Study opens door to new approaches for preventing the development of metabolic diseases

The protein Asc-1 regulates whether fat-burning beige or fat-storing white adipocytes are formed, which can have an impact on the development of metabolic diseases.

New molecular pathway helps steer moving cells in specific directions

Working with fruit flies, scientists at Johns Hopkins Medicine say they have identified a new molecular pathway that helps steer moving cells in specific directions.

Research sheds light on a new neuroprotective mechanism to control damage following brain injury

When the brain suffers injury or infection, glial cells surrounding the affected site act to preserve the brain's sensitive nerve cells and prevent excessive damage.

Scientists produce high-resolution 3D image of sarcomere using electron cryo-tomography

Scientists have produced the first high-resolution 3D image of the sarcomere, the basic contractile unit of skeletal and heart muscle cells, by using electron cryo-tomography (cryo-ET).

Biological “feed-forward” loop contributes to progression of osteoarthritis

An unfortunate biological "feed-forward" loop drives cartilage cells in an arthritic joint to actually contribute to progression of the disease, say researchers at Duke University and Washington University in Saint Louis.

Study reveals how cells build 'mini-muscles' underneath their nucleus

Research groups at the University of Helsinki uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the cell membrane.

RIG-1-like receptors may play dominant role in suppressing SARS-CoV-2 infection

A new study by researchers at the University of Connecticut Health Center, USA, reports the crucial nature of the pathogen pattern recognition receptor (PRRs), especially the two RLRs, retinoic acid-inducible gene I (RIG-I) and melanoma differentiation-associated protein 5 (MDA5), in triggering host cell immune responses within the cell. The RLRs are viral RNA sensors.

Researchers receive $1,894,271 grant to address new drug targets for diastolic dysfunction

After the left ventricle of the heart contracts, it must relax efficiently to prepare to refill and supply the body with blood on the next beat. An increasing number of patients -- including nearly all patients with heart failure -- suffer from impaired relaxation, which is part of a clinical syndrome known as diastolic dysfunction. Currently, treatments for impaired relaxation do not exist.

New discovery revises the ‘text book view’ of cell migration

Research groups at University of Helsinki and Institut Jacques Monod, Paris, discovered a new molecular mechanism that promotes cell migration.
