Biologists from the University of California Los Angeles (UCLA), United States, found the gene PGC-1 inhibitors aging fruit flies (Drosophila melanogaster). This increases the activity of mitochondrial genes: a major energy-producing organs of cells controlling cell growth and to tell when to live or die.

Assistant professor of integrative biology and physiology at UCLA, David Walker, PGC-1 gene testing this by placing it on other networks in fruit flies. The result, when PGC-1 is placed on the digestive tract of flies, the flies live longer, up to 50 percent of the age of his life which are generally only two months.

"These results are not apparent when PGC-1 gene was placed on a network of nerves, muscles and other tissues," he said, Wednesday (9 / 11).

During this time, the experts think of aging can be inhibited by the brain or heart tissue. Apparently, the intestine plays a major role inhibiting aging, not only in the absorption of food. Also inhibit intestinal toxins and pathogens from the environment.

These genes can be used for drugs against diseases related to aging, such as Alzheimer's, Parkinson's, cancer, and heart.
