An international group of scientists studied the effects of 17 lifespan-extending interventions on gene activity in mice and discovered genetic biomarkers of longevity. The results of their study were published in the journal Cell Metabolism.
Nowadays, dozens of interventions are known that extend the lifespan of various living organisms ranging from yeast to mammals. They include chemical compounds (e.g. rapamycin), genetic interventions (e.g. mutations associated with disruption of growth hormone synthesis), and diets (e.g. caloric restriction). Some targets of these interventions have been discovered. However, there is still no clear understanding of the systemic molecular mechanisms leading to lifespan extension.
Group - Scientists - Skoltech - Moscow - State
A group of scientists from Skoltech, Moscow State University and Harvard University decided to fill this gap and identify crucial molecular processes associated with longevity. To do so, they looked at the effects of various lifespan-extending interventions on the activity of genes in a mouse, a commonly used model organism closely related to humans.
The scientists identified a group of genes, whose activity was associated with longevity in response to various interventions, serving as biomarkers of lifespan extension.
Lab - Mice - Sexes - Ages - Longevity
"In our lab, we subjected mice of different sexes and ages to 8 longevity interventions and analyzed gene expression changes induced...
