Genetic influences on health can ripple through social groups via shared microbes
Your «roommate’s» genes could be influencing the bacteria living in your gut, and vice versa, according to a study of rats published in Nature Communications.

Individual genetic differences can render some antibody-based therapies ineffective
Antibody-based therapies are used to treat numerous diseases, from cancer to rheumatic disorders and multiple sclerosis. Antibodies recognize and bind to very specific structures. This allows them to direct active substances to exactly the right target…

‘Molecular glue’ stabilizes protein that inhibits development of non-small cell lung cancer
Lung cancer is the second-most common cancer and the leading cause of cancer death in the United States. Over 80% of lung cancers are non-small cell lung cancers, in which tumor cells are larger and grow more slowly than those in small cell lung cancer.

How disabling one gene protects mice against Type 1 diabetes
Scientists at the University of Wisconsin–Madison have uncovered a possible way to protect key cells in the pancreas that are targeted during the development of Type 1 diabetes.

Gene therapy advances as scientists guide jumping DNA to target faulty genes
JABSOM Cell and Molecular Biology researcher Dr. Jesse Owens has spent the better part of two decades chasing a vision that began with the revolutionary idea that DNA can move itself. Now, his team’s latest breakthrough is published in Nucleic Acids Re…

New details on role of fat transport molecules in Alzheimer’s onset
A new study presents robust evidence on the role of lysophosphatidylcholines (LPCs) in the onset of Alzheimer’s disease. Researchers discovered that LPCs—compounds that transport a variety of healthy fatty acids to the brain—either promote Alzheimer’s …

Using both genetic information and AI to diagnose pneumonia could curb the overuse of antibiotics
Lung infections like pneumonia are among the world’s top killers—but diagnosing them is notoriously hard. Now, researchers at UC San Francisco have found a way to identify these infections in critically ill patients by pairing a generative AI analysis …

Multiple myeloma develops differently in men and women, study reveals
Researchers at the Indiana University Melvin and Bren Simon Comprehensive Cancer Center have uncovered biological differences in how multiple myeloma develops and progresses in men and in women. The rare blood cancer occurs more often in men than in wo…

Alcohol-linked DNA damage tied to cancer risk: Study reveals repair enzyme’s role
Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA. A research team from IOCB Prague has now described in detail how cells repair this damaged genetic information.
