Scientists from Harvard Medical School claimed that they have finally found the ‘elixir of youth’ which can not only slow down the aging process, but also reverse it. This rejuvenating substance created by American scientists currently works only on mice.
“We worked on understanding the mechanisms of aging and conducted experiments on mice. For this purpose we selected mature enough animals that were older than two years, and began to introduce the experimental drug. To our surprise, just in a week the mice got younger. They became vigorous and energetic as if they were six-month old,” said Prof David Sinclair of Harvard Medical School.
The muscles of the rejuvenated mice were in tone, and their cardiac muscles were as new. It’s as if a 60-year-old man turned into a 17-year-old. The coenzyme nicotinamide adenine dinucleotide (NAD) has played a major role in this incredible transformation. In a living organism, NAD serves as a conduit between the nucleus and mitochondria. The latter generates energy, and NAD delivers it to the cell nucleus. At low concentration of NAD, communication between mitochondria and the nucleus of cells weakens.
