New experiment shows aging is possible reverse via DNA trick
December 1st 2010 07:41
A telomere is a region of repetitive DNA at the end of a chromosome, which protects the end of the chromosome from deterioration. The telomere regions defer the degradation of genes near the ends of chromosomes by allowing for the shortening of chromosome ends, which necessarily occurs during chromosome replication. Cells stop dividing and die when telomeres drop below a certain length. Ageing happens.
The video below explains telomeres in detail.
Mariela Jaskelioff and her colleagues at the Dana Farber Cancer Institute in Boston, Massachusetts, injected the mice with a drug that switched on a gene, which stimulated telomerase production. Four weeks after the team switched on the enzyme, they found that the treated mice showed surprising signs of rejuvenation. The mouse testes produced new, viable sperm cells, their brains began producing new cells and they were living longer.
