Scientists implicate disruption in prenatal neurogenesis in the development of autism

A new study of autism risk genes by UC San Francisco and UC Berkeley scientists implicates disruption in prenatal neurogenesis - a process in which specialized "progenitor" cells give rise to new brain cells - in the development of autism spectrum disorders (ASDs).

$1.8 million NIH grant supports research on extracellular vesicles

Scientists have known for decades that our cells constantly shed tiny pieces known as extracellular vesicles (EVs), but until relatively recently they believed that this process was merely a way for cells to rid themselves of material that was no longer needed.

AI analyzes tissue scans to identify cancer patients at risk of hyperprogressive disease

Researchers at Case Western Reserve University, using artificial intelligence (AI) to analyze simple tissue scans, say they have discovered biomarkers that could tell doctors which lung cancer patients might actually get worse from immunotherapy.

Fecal microbiota transplant helps cancer patients respond to immunotherapy

For patients with cancers that do not respond to immunotherapy drugs, adjusting the composition of microorganisms in the intestines--known as the gut microbiome--through the use of a stool, or fecal, transplants may help some of these individuals respond to the immunotherapy drugs, a new study suggests.

Researchers explore the regulatory role of protein in human health and disease

Researchers from the University of Virginia, Lehigh University and the Massachusetts Institute of Technology are pooling their respective labs' expertise to unlock the mysteries of a protein that plays a critical regulatory role in human health and disease.

Scientists identify new drug target for treating Hutchinson-Gilford progeria syndrome

Researchers have discovered a promising treatment method for Hutchinson-Gilford progeria syndrome (HGPS)—a debilitating genetic disorder that accounts for rapid and premature aging in children.

Advances in cancer research can expand effectiveness of immunotherapy

Scientists are hoping advances in cancer research could lead to a day when a patient's own immune system could be used to fight and destroy a wide range of tumors.

Researchers study the formation of reinforced, patterned cell walls during proto-xylem development

Trees are by far the tallest organisms on Earth. Height growth is made possible by a specialized vascular system that conducts water from the roots to the leaves with high efficiency, while simultaneously providing stability.

Breast cancer-on-a-chip for rapid screening of immunotherapeutic drugs

There are many mechanisms by which the body responds to foreign invaders. One of these involves the T-cells of the immune system, which have a number of different proteins on their surface called "checkpoint proteins."

Toxin-antitoxin systems negatively control plasmid replication

According to Thomas Wood, Biotechnology Endowed Chair and Professor of Chemical Engineering at the Penn State College of Engineering., toxin-antitoxin (TA) structures are currently known to adversely regulate the replication of plasmids.

Yale scientists discover novel metabolic gatekeeper mechanism for leukemia

In a new study led by Yale Cancer Center, researchers have discovered a novel metabolic gatekeeper mechanism for leukemia. This mechanism depends on a molecule called PON2, which could lead to a new treatment for the disease. The findings were published online today in the Proceedings of the National Academy of Sciences (PNAS).
