Scientists at Northwestern University have discovered a genetic mutation in an isolated Amish population that helps them live longer and healthier lives, and protects them from diabetes and other age-related illnesses. A drug that mimics those effects is currently being trialled in humans, and shows promise in slowing aging, preventing diabetes and may even counteract baldness.
The mutation was discovered in an Amish extended family (or "kindred") living in Berne, Indiana, part of a community that has largely remained genetically isolated for over a century. Carriers were found to live on average 10 percent longer (about 14 years) than those without, be significantly less likely to develop diabetes and have much healthier vascular systems into old age. Their telomeres protective caps on the ends of chromosomes that shorten with age were 10 percent longer than average, and they had much lower fasting insulin levels.
"The findings astonished us because of the consistency of the anti-aging benefits across multiple body systems," says Douglas Vaughan, lead author of a paper describing the find. "For the first time we are seeing a molecular marker of aging (telomere length), a metabolic marker of aging (fasting insulin levels) and a cardiovascular marker of aging (blood pressure and blood vessel stiffness
