Researchers use heat map data to reverse engineer chromosome models

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes -- the highly complex, three-dimensional structures that hold genetic information.

Targeting RNA splicing can trigger antiviral immune pathways in triple-negative breast cancers

Researchers at Baylor College of Medicine have discovered how therapeutics targeting RNA splicing can activate antiviral immune pathways in triple negative breast cancers (TNBC) to trigger tumor cell death and signal the body's immune response.

New type of stem cell with regenerative abilities could soon become a reality

A new type of stem cell - that is, a cell with regenerative abilities - could be closer on the horizon, a new study led by UNSW Sydney shows.

Metabolites may be predictive indicators for recurrent major depressive disorder

Researchers at University of California San Diego School of Medicine, in collaboration with Dutch scientists, have found that certain metabolites -- small molecules produced by the process of metabolism -- may be predictive indicators for persons at risk for recurrent major depressive disorder.

Scientists identify the sensor in human lungs that detects SARS-CoV-2

Scientists at Sanford Burnham Prebys Medical Discovery Institute have identified the sensor in human lungs that detects SARS-CoV-2 and signals that it's time to mount an antiviral response.

Protein phosphatase inhibition could contribute to the treatment of cancer, other diseases

The abundant presence of an enzyme known as low molecular weight protein tyrosine phosphatase (LMWPTP) in tumor cells has long been considered an indicator of cancer aggressiveness and metastatic potential.

Nanobodies can prevent entry of SARS-CoV-2 coronavirus into human cells

Researchers at Karolinska Institutet in Sweden have developed, in collaboration with researchers in Germany and the U.S., new small antibodies, also known as nanobodies, which prevent the SARS-CoV-2 coronavirus from entering human cells.

Researchers develop novel nanobodies against SARS coronavirus-2

An international research team led by the University of Bonn has identified and further developed novel antibody fragments against the SARS coronavirus-2. These "nanobodies" are much smaller than the classic antibodies used to treat US President Donald Trump, for example.

Researchers determine atomic structure of coronavirus protein linked to disease severity

A team of HIV researchers, cellular biologists, and biophysicists who banded together to support COVID-19 science determined the atomic structure of a coronavirus protein thought to help the pathogen evade and dampen response from human immune cells.

Augmented response of immune system explains COVID-19 severity in patients with hypertension

COVID-19 patients who also suffer from high blood pressure are more likely to fall severely ill with the disease, which also leaves them at greater risk of death.

Study reveals richness of space-time gene expression dynamics of the liver

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".

New discovery helps explain how COVID-19 suppresses the body’s immune response

Seeking to understand why COVID-19 is able to suppress the body's immune response, new research from the USC Leonard Davis School of Gerontology suggests that mitochondria are one of the first lines of defense against COVID-19 and identifies key differences in how SARS-CoV-2, the virus that causes COVID-19, interacts with mitochondrial genes when compared to other viruses.

Researchers show how the genetic material travels from cell to cell

The genetic material of plants, animals, and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here.
