Swedish researchers from Uppsala University have found the answer to the well-known phenomenon of the length of women's life. It is known that men live according to statistics fewer women - experts found this is due to the very fact of their masculinity.
The research team, led by Dr. Lars Forsberg, concluded that There is a clear link between the behavior of the "male» Y-chromosomes in the cells of the blood, short life expectancy between an increased risk of death from internal cancers.
Actually men generally not only live less than women. but more than the weaker sex, prone to develop cancer (in this case, statistically, in men and higher mortality from cancer). Swedish researchers believe that the reason for this vulnerability strong half of mankind is the loss of the Y-chromosome white blood cells.
According to the journal Nature Genetics, geneticists have been carefully studied blood samples from more than 1,600 elderly men and. Medical observation of the study participants were conducted over the years. the loss of the Y-chromosome. Scientists have seen that the level of the Y-chromosome in the cells of the blood of men closely It linked to life expectancy.
Recall that the Y-chromosome contains genes that determine the sex (male) and are involved in the development of the seed. Research Swedish scientists have made changes in the long-existing understanding of the status of Y-chromosome. "According to previous study, Y-chromosome contains very little genetic information. But, according to our results, it is not true: Y -hromosoma contains very little genetic information, but plays an important role in inhibiting the growth of tumor tissue, "- said in this connection, one of the authors, Professor Ian Dumanskaya.
Note that science is not the first time receives proof that utrachivanie Y-chromosome may be associated with high risk of cancer. The work of Israeli scientists has shown that the level of "male" chromosome correlates with the probability of developing prostate cancer. According to their research, Fathers with only daughters had a higher risk of prostate cancer than men with, at least one son. (READ MORE)

"Men who have lost Y-chromosome in a large part of blood cells have a lower level survival. We also found a correlation between the loss of the Y-chromosome and increased mortality from cancer, "- said on this occasion the research curator Lars Forsberg.
