Key protein identified for brain stem cell longevity

A receptor that was first identified as necessary for insulin action, that also is located on the neural stem cells found deep in the brains of mice, is pivotal for brain stem cell longevity, according to a Rutgers study, ...

Gene in fat plays key role in insulin resistance

Deleting a key gene in mice in just their fat made tissues throughout these animals insulin resistant, in addition to other effects, a new study by UT Southwestern researchers shows. The findings, reported in a recent issue ...

Key mechanism in insulin release by cholesterol metabolite

Insulin which is released by pancreatic beta-cells is the main regulator of blood sugar. Previous and current studies by a research group at Lund University in Sweden have identified around hundred different receptors on ...

Scientists link 'hunger hormone' to memory in Alzheimer's study

Scientists at The University of Texas at Dallas have found evidence suggesting that resistance to the "hunger hormone" ghrelin in the brain is linked to the cognitive impairments and memory loss associated with Alzheimer's ...

Research sheds new light on how brain stem cells are activated

Our brains are notoriously bad at regenerating cells that have been lost through injury or disease. While therapies using neural stem cells (NSCs) hold the promise of replacing lost cells, scientists need to better understand ...
