Scientists have refuted the effect of anti-aging protein

A new study has shown that a protein which, as previously stated, rejuvenates the body, it actually brings more harm, inhibiting the ability of cells to repair itself. In previous studies it was found that the protein GDF11 has a miraculous effect when the connection of the circulatory systems of aged and young mice the "old man" the regeneration of the atrophied muscles and restore cognitive abilities.

Stem-cell researcher Amy Wagers (Amy Wagers) from Harvard University in Cambridge (Massachusetts, USA) offered an explanation of the doping effect of combining the circulatory systems of two organisms. Scientist demonstrated that injections of the protein GDF11, the content of which in the blood of mice declines with age, helped them to rejuvenate.

However, the research team institutes for biomedical research Novartis in Cambridge said that in reality "anti-aging" protein has a negative effect on living tissue. Scientists have demonstrated that a set of reagents that are used by their colleagues, can not distinguish the protein myostatin, GDF11 from. Apparently, Weijers confused squirrel.

"Myostatin inhibits the growth and differentiation of muscle tissue", writes the journal Nature.

Using a more specific reagent to measure the levels of GDF11 in the blood of rats and humans, the researchers found age-related increase in the level of GDF11, not decrease, as shown by previous studies. Regular injection of GDF11 in the blood of experimental animals has had a negative impact on the health of muscle tissues.

The study was published in the journal Cell Metabolism.

However, to explain why this is happening, a team of Novartis could not.

In turn, Wagers believes that GDF11 may have several forms and only one of them declines with age. Both studies agree that too low or too high protein harms the body.

According to her, professionals Novartis was first seriously damaged the muscles and then treated them with plenty of protein. Therefore, they failed to achieve rejuvenating results.published
