TSRI scientists identify new gene variants closely associated with bipolar disorder

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified small variations in a number of genes that are closely linked to an increased risk of bipolar disorder, a mental illness that affects nearly six million Americans, according to the National Institute of Mental Health.

Scientists discover mechanism used by A20 protein to combat inflammation

Scientists affiliated with VIB and UGent have discovered a mechanism used by the protein A20 to combat inflammation. This could be a very important point of focus in the search for a treatment for autoimmune diseases such as Rheumatoid Arthritis, in which the patient suffers from chronic, uncontrolled inflammation.

NCI awards Provocative Questions grant to Mount Sinai School of Medicine researchers

Two Mount Sinai School of Medicine researchers are among a select group of scientists from around the world who have been recognized by the National Cancer Institute (NCI) for their quest to answer the most pressing questions about cancer. Stuart Aaronson, MD, Professor and Chair of Oncological Sciences and Ross Cagan, PhD, Professor of Oncological Sciences at Mount Sinai, have received the NCI's new "Provocative Questions" grant, which was established to explore the important yet less obvious questions about cancer that may have been neglected in this era of significant discovery.

PCA inhibits multiple pathways involved in development of diabetic nephropathy

Diabetic nephropathy is one of the most serious complications related to diabetes, often leading to end-stage kidney disease. Purple corn grown in Peru and Chile is a relative of blue corn, which is readily available in the U.S.

Biologists elucidate how muscle stem cells colonize special niches

Muscles have a pool of stem cells which provides a source for muscle growth and for regeneration of injured muscles. The stem cells must reside in special niches of the muscle for efficient growth and repair.

Brigham Young University scientists discover cellular cause of birth defects

The cellular cause of birth defects like cleft palates, missing teeth and problems with fingers and toes has been a tricky puzzle for scientists. Now Professor Emily Bates and her biochemistry students at Brigham Young University have placed an important piece of the developmental puzzle. They studied an ion channel that regulates the electrical charge of a cell. In a new study published by the journal Development, they show that blocking this channel disrupts the work of a protein that is supposed to carry marching orders to the nucleus.

Blocking GSK3b enzyme can prevent bacterial-induced periodontal bone loss

A University of Louisville scientist has found a way to prevent inflammation and bone loss surrounding the teeth by blocking a natural signaling pathway of the enzyme GSK3b, which plays an important role in directing the immune response.

Mount Sinai scientists identify cancer’s Achilles heel

Scientists at Mount Sinai School of Medicine have discovered a subpopulation of cells that display cancer stem cell properties and resistance to chemotherapy, and participate in tumor progression. This breakthrough could lead to the development of new tests for early cancer diagnosis, prognostic tests, and innovative therapeutic strategies, as reported in Cancer Cell.

Researchers gain new insight into regulation of adult nerve cell generation in the hypothalamus

Researchers from the University of Utah have gained new insight into the regulation of adult nerve cell generation in the hypothalamus, the part of the brain that regulates many aspects of behavior, mood, and metabolism.

New strategy will have positive impact on people with brain disorders

New research offers a possible strategy for treating central nervous system diseases, such as brain and spinal cord injury, brain cancer, epilepsy, and neurological complications of HIV. The experimental treatment method allows small therapeutic agents to safely cross the blood-brain barrier in laboratory rats by turning off P-glycoprotein, one of the main gatekeepers preventing medicinal drugs from reaching their intended targets in the brain.

TSC and PTEN genes important in controlling blood precursor cells in Drosophila

UCLA stem cell scientists have shown that two common tumor suppressor genes, TSC and PTEN, are vital to regulating the stem cell-like precursor cells that create the blood supply in Drosophila, the common fruit fly.

Scientists decode signals that boost the burning of fat

The numbers of obese people are climbing steeply all over the world - with obvious major consequences for their health. Due to excess food intake and a lack of physical activity, but also due to genetic factors, the risk for overweight people dying from diseases like coronary heart disease, diabetes und atherosclerosis increases.
