The longevity gene also protects against senile dementia

In carriers of two copies of the "longevity gene", memory deteriorated less quickly, and the risk of developing senile dementia was reduced. The risk of Alzheimer's disease, for example, was as much as 70% lower.

How to preserve aging muscles

Blocking the molecules responsible for muscle aging will help people stay physically active longer and look younger. Mice with rapidly aging muscles will help to find such molecules and ways to influence them.

The solution to obesity: make muscles gluttonous

For the treatment of obesity, one of the proteins of the shell of muscle cells can be turned off, as a result of which their efficiency decreases and the body spends more energy both at rest and during physical activity.

Another cause of Alzheimer's disease?

A small peptide fragment cleaved from the beta-amyloid precursor protein causes the same damage to cellular structures as the formation of amyloid plaques. These data open up new ways to find remedies for the treatment of Alzheimer's disease.
