Longevity Gene stronger gene hereditary disease

This is the conclusion a group of scientists at Boston University in the U.S., led by Professor Thomas Perlsam. Experts compared the genomes of 801 American from the age group of 95 to 119 years with the genomes of 926 members of the younger generation. The analysis showed that there is a kind of genetic pattern that combines all the centenarians.

Using so-called Genetic markers Boston professor and his colleagues are going to soon determine the life expectancy of a person with an accuracy of 77%. Perlsa Group has developed a special chip that will allow the laboratory by identifying a gene long and healthy life on a drop of blood.

One drop of blood Boston scientists hope to soon determine the life expectancy of a person with an accuracy of 77% …

As the researchers, their quest is not reduced to the study of only one gene. Boston group was able to construct a model of a variety of genetic differences that allow a person to live to a ripe old age. The model accounts for 150 distributions throughout the genome polimarfemav (SNP), in other words — genetic units that can be substituted for each other.

As experts believe, in the presence of such a combination, each of us, in principle, can live up to 100 years or more, and not at the risk of Alzheimer's disease, Parkinson's or cardiovascular pathology.

In the international scientific publications have appeared first comments on the opening of Boston scientists.

Geneticist with the global name Marcus Noten the University of Bonn in Germany, called the study a real breakthrough in matters of longevity.

Due to their genetic characteristics, women in almost all countriess live significantly longer than men. This is typical of other mammals …

Meanwhile kembrydkih group of scientists went even further. By studying the issues of longevity, a team of researchers led by Professor Tamahira Kono came to the following conclusion: for a small lifetime is responsible specific genetic unit — Rasgrf1. That is to say, the male gene that is passed through the father. Despite the fact that it is obtained inheritance and female, from this latter gene is inactive. As demonstrated by studies in mice, the rodents that have emerged through genetic engineering, without the "parents" live three times longer than mice with a normal genetic heritage.

"We have long been known that women in almost all countriess live significantly longer than men. This is the case in other mammals. Our results showed that the genetic material, which is at spermatazoidnyh cells, affects the life span of this type, "- says Professor Tamahira Kono.
