An evolutionary human foraging instinct, fueled by fructose production in the brain, may hold clues to the development and possible treatment of Alzheimer’s disease (AD), according to researchers at the University of Colorado Anschutz Medical Campus.

The study, published recently in The American Journal of Clinical Nutrition, offers a new way of looking at a fatal disease characterized by abnormal accumulations of proteins in the brain that slowly erode memory and cognition.

“We make the case that Alzheimer’s disease is driven by diet,” said the study’s lead author Richard Johnson, MD, professor at the University of Colorado School of Medicine specializing in renal disease and hypertension...

DNA can help to stimulate bone healing in a localised and targeted manner, for example after a complicated fracture or after severe tissue loss following surgery...

As we age, the end caps of our chromosomes, called telomeres, gradually shorten. Now, Salk scientists have discovered that when telomeres become very short, they communicate with mitochondria, the cell’s powerhouses. This communication triggers a complex set of signaling pathways and initiates an inflammatory response that destroys cells that could otherwise become cancerous.

The findings, published in Nature on February 8, 2023, could lead to new ways of preventing and treating cancer as well as designing better interventions to offset the harmful consequences of aging.

The discovery is the result of a collaboration between co-senior authors ...
