New micro-protein supports cell division and proliferation during nutrient scarcity

Researchers from the University of Eastern Finland and the University of Montreal (Canada) have discovered that a micro-protein, which they named Nrs1, supports cell division and proliferation when nutrients are scarce.

Cardiovascular markers for predicting clinical outcomes in SARS-CoV-2 infection

In a recent study posted to the medRxiv* preprint server, an interdisciplinary team of researchers from Toronto, Canada, characterized the markers of endothelial function and developed micro ribonucleic acid (miRNA) expression atlas in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive and -negative patients admitted to the intensive care unit (ICU).

Group cell movement could be harnessed to stop cancer spread, study suggests

Cells push and pull on surrounding tissue to move in groups as they form organs in an embryo, track down invading bacteria, and become cancerous and spread.

Impact of DNA clearance on mortality in patients with severe COVID-19 infections

In a new study, researchers conducted activity-based proteomic profiling of patients who had severe SARS-CoV-2 infections to understand the impact of DNA clearance on mortality.

Scientists explore how proteins bind with specific companions inside cells

Despite its minute size, a single cell contains billions of molecules that bustle around and bind to one another, carrying out vital functions. The human genome encodes about 20,000 proteins, most of which interact with partner proteins to mediate upwards of 400,000 distinct interactions.

SARS-CoV-2 virus co-opts intrinsic cellular machinery to suppress interferon production

In a recent study posted to the bioRxiv* preprint server, researchers evaluated the mechanism of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated inflammatory marker interferon (IFN) repression in hosts.

An algorithm to predict host cleavage targets of SARS-CoV-2 3CLPro

In a recent study posted to the bioRxiv* preprint server, researchers developed a novel bioinformatic algorithm to predict host cleavage targets of the SARS-CoV-2 3C-like protease (3CLPro).

Long-term use of blood pressure medication could be contributing to kidney damage

New kidney research from the University of Virginia School of Medicine is raising concerns that long-term use of drugs commonly prescribed to treat high-blood pressure and heart failure could be contributing to kidney damage.

Food science experts characterize the properties of protein in several insect powders

As the human population grows to a predicted 10 billion by 2050 and overall land mass remains constant, traditional animal farming may become a less viable method for food production.

Researchers study immune cell invasion process in living fruit fly embryos

To fight infections and heal injuries, immune cells need to enter tissue. They also need to invade tumors to fight them from within.

New optogenetic tool uses focused light to reduce actin and myosin-based contractile force

Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a research team led by the Division of Quantitative Biology at the National Institute for Basic Biology in Japan has successfully developed "OptoMYPT"：an optogenetic tool that utilizes focused light to reduce actin and myosin-based contractile force.
