Scientists have discovered a simple method of predicting life expectancy
MOSCOW, 01 Sep — RIA Novosti. Scientists from Germany, the Netherlands, USA and Japan have discovered a simple method of determining life expectancy. A study published in the journal Nature Communications.
Experts have found a correlation between the size of nucleoli in the cells of free-living nematodes and their life expectancy. The smaller the size of intranuclear cellular component, the higher is the expected lifespan of the animal. The same pattern the researchers were able to find well as fruit flies and rodents. Scientists found that intense exercise performed by animals, caused a decrease in the size of nucleoli.
Biopsy the muscle tissue of people older than 60 years showed that this pattern is true for humans.
The researchers also found that the smaller the nucleus, the less it protein fibrillarin. Scientists believe that the size of this part may act as a marker of life expectancy.
