American scientists made an amazing discovery. Researchers from the University of Washington in Seattle discovered a whole set of so-called “death genes”, activated in cells a few hours after the death of a living creature.
According to experts, they made this find by accident. how it is known that the processes occurring in the body after death are still not yet fully understood by scientists. Desiring to satisfy my scientific curiosity, experts tracked how corpses behave animals. Study author Peter Noble claims that by studying death, you can get extremely valuable information on how it works a life.
Noble, along with his colleagues, determined that in the body of animals there are certain genes that start working only after death of their owners. In particular, such functional and structural units of heredity were found in cells zebra fish and mice. Experts killed experimental creatures lethal doses of poison and began to observe the processes occurring in the cells of corpses.
Experts have noticed that after the brain stops working and activity of proteins and genes in the cardiovascular system changed dead organisms are not arbitrary, as one might suggest, but in a certain sequence. It turned out that in the cells there are hundreds of genes involved in work through some time after the death of the body and stably functioning several days.
Death genes have been very interesting for life
Scientists note that many of these genes tried literally to revive a corpse, enhancing the immune response in a dead body, protecting tissues from inflammation and suppressing onset processes decomposition. To the defeat of the Americans, many “zombie genes” were the same sections of deoxyribonucleic acid that responded for embryonic development of the body, while disconnected after body formation and birth.

“It feels like after stopping the work of the brain and heart the body still does not believe in its death and as if trying to come to life, activating these genes, “says Peter Noble.
It is also very interesting that in the cells of dead mice and fish genes associated with the development of oncology were activated. Perhaps this explains the fact that organ transplantation of the dead people sometimes provokes the development of malignant recipients tumors.
The authors of the discovery are convinced that the pattern of activity of the “death genes”, which the Americans have already called a thanatotranscript, maybe used by experts to determine the exact time of death of a person and ascertaining whether his organs can be used for transplantation.
