In human blood, there is a biomarker of death

Elevated levels of certain molecules in the serum indicates a relatively high probability of death of a person about the next ten years. This is the conclusion of the Swedish scientists who observe the two thousand compatriots.

Biologists and physicians at the University of Uppsala nearly 20 years followed by two large groups of men and women with an average age (at the beginning of the project) in 70 years. Within 8-13 years, about a quarter of the wards died.

Now the authors of shoveled Statistics, given the known factors that influence the probability of death - the exact age of the person, the development of disease, taking medication, weight and blood pressure, smoking and so on. After deducting all the effects remained a statistical link between the death and the high level of circulating in the body of cathepsin C (cathepsin S).

According to Technology Review, the wards with the highest content of cathepsin C showed twice as likely to die in the next few years than men with the lowest levels of the molecule. In addition, it was found that patients with high (against the average value) of cathepsin C content more frequently than others to die from heart disease and cancer.

Apparently, the molecule (existing at all, and participated in a number of biochemical processes) increased their output of signal capable of development of the two most common types of diseases leading to death, and it is very unusual, Swedish researchers emphasize.

However, how accurate level measurement of cathepsin C can predict the risk of death or disease mentioned - is not clear. It is unknown, particularly whether it is a biomarker associated with heart disease and cancer, or it simply indicates poor general health and development of aging.
