A new study on American scientists discusses the usual idea of how the health of the unborn child is formed. It was revealed that parents’ DNA not only carries hereditary signs, but also actively affecting biological aging from the early days of life even during the embryo stage.
We talk about the telomers at the ends of chromosomes that shorten with each cell division. Those who participate in the aging process of the body and are related to the development of cancer according to scientists. Until recently, the length of the telomeres was believed to be only a genetic lottery: what my mother and father have surrendered, you are experiencing with this. However, the results of the new study showed: everything is much more complex.
Professors of the University of Pennsylvania found that telomeres could not only be transmitted from the embryos, but also could be extended or shortened depending on the DNA of the parents. For example, if the father has long telomeres and the mother has short ones, they are actively growing in the oldest child. However, with the opposite combination, they decrease. If the telomers of the parents are approximately the same, they remain constant.
Discovery was carried out on the basis of experiments with mice, but scientists emphasize: similar patterns have been observed in humans before. In particular, in children of more age -related fathers, telomeres are generally known to be longer than young parents’ children. Previously, this was explained by external factors such as stress and diet, but now it became clear – it could also be in the nature of parent DNA interaction.
Another unexpected finding: The prolongation of telomeres in the early stages was accompanied by the inclusion of a process called sub -process, which is an alternative mechanism for the extension of telomers that are active only in cancer cells. However, in embryos, this path is naturally put on the market, which can help scientists understand how cancer and aging develop at the molecular level.
