An anti-aging treatment successfully tested

American researchers in a laboratory experiment, they were able to significantly rejuvenate muscle. An exciting discovery Dr. Ana Gomez, of the Department of Genetics at Harvard Medical School does not pretend enthusiasm. The researcher has managed a feat: partially reverse the aging mechanism. While age is considered an immutable process, the team of U.S. researchers has demonstrated that some aspects could be reversed.

In the scientific journal Cell, they have focused on explaining a chemical called NAD whose cell concentration naturally reduces with age. This molecule impede the functioning of mitochondria, cells energy factories, which participates in the mechanism of cell aging.

The researchers found that increasing the cellular level of NAD in a mouse had an incredible anti-aging effect . This treatment administered for a week in a mouse two years has clearly rejuvenated its muscles. They became similar to those of mice six months to several levels as mitochondrial function, insulin resistance and inflammation. Muscle became stronger and resistant as in her youth.

A multifactorial mechanism

This discovery is important but unfortunately does not solve the riddle of aging. Other aspects of the process to date can not be reversed. We do not know for example how to prevent the shortening of telomeres (the ends of chromosomes) or DNA damage. "Aging is multifactorial," says Ana Gomez.

It will have to wait a little longer to expect to live one day experience of Benjamin Button. However, research is moving fast. Other Harvard researchers have recently succeeded in repelling hairs on mice by manipulating a gene capable of regenerating cells .
