Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Buck Institute for Research on Aging scientists have uncovered a role for a gene called OXR1 that is necessary for the lifespan extension seen with dietary restriction and is essential for healthy brain aging.

“When people restrict the amount of food that they eat, they typically think it might affect their digestive tract or fat buildup, but not necessarily about how it affects the brain,” said Kenneth Wilson, Ph.D...

Bonn researchers identify protein that increases the formation of good brown and beige fat. Brown fat cells convert energy into heat — a key to eliminating unwanted fat deposits. In addition, they also protect against cardiovascular diseases. Researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research Area “Life & Health” at the University of Bonn have now identified the protein EPAC1 as a new pharmacological target to increase brown fat mass and activity. The long-term aim is to find medicines that support weight loss...

Lifespan Increases in Mice when Specific Brain Cells are Activated, study finds

In recent years, research has begun to reveal that the lines of communication between the body’s organs are key regulators of aging. When these lines are open, the body’s organs and systems work well together. But with age, communication lines deteriorate, and organs don’t get the molecular and electrical messages they need to function properly.

A new study from Washington University School of Medicine in St. Louis identifies, in mice, a critical communication pathway connecting the brain and the body’s fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.

The study—published in the jour...

Scientists Tame Chaotic Protein Fueling 75% of Cancers

Discovery opens window to more effective treatment. Meet MYC, the shapeless protein responsible for making the majority of human cancer cases worse. UC Riverside researchers have found a way to rein it in, offering hope for a new era of treatments.

In healthy cells, MYC helps guide the process of transcription, in which genetic information is converted from DNA into RNA and, eventually, into proteins.

“Normally, MYC’s activity is strictly controlled...
