Study defines the most crucial genes that Increase risk of breast cancer

Genetic inheritance affects the likelihood of developing breast cancer. Some genes are already known to increase cancer risk; other genes are suspected to be involved, but not to what extent. It is crucial to clarify this issue to improve prevention since it opens the way to more personalized follow-up and screening programs.

Immunity of COVID-19 patients may rely on antibodies from previous coronavirus infections

The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

Antibiotic resistance may be spreading much faster than expected

Pathogenic bacteria in humans are developing resistance to antibiotics much faster than expected. Now, computational research at Chalmers University of Technology, Sweden, shows that one reason could be significant genetic transfer between bacteria in our ecosystems and to humans. This work has also led to new tools for resistance researchers.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.

Researchers define cancer invasion machinery orchestrated by cancer gene

Researchers at the University of Helsinki have defined a cancer invasion machinery, which is orchestrated by a frequently mutated cancer gene called Ras. When signaling from Ras protein becomes abnormally high, like it does in many cancers, this switches on the cellular machinery that helps the cancer cells to depart from the tissue from which the cells have developed.

New computational technique accurately differentiates between normal and cancer cells

Scientists have created a new method to precisely differentiate between data from a wide range of normal cells and cancer cells found inside tumor samples.

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.

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".
