Interesting Fly Longevity Research
Permalink | View Comments (0) | Post Comment | | Posted by Reason

EurekAlert brings us interesting research in flies: scientists "showed in 2003 that boosting the amount of a molecular signal known as JNK in a fruit fly allows the fly to live 85 days instead of 60, by spurring the fly to defend itself more aggressively against the oxidative stress that accelerates with aging. ... While scientists knew that JNK in a fly cranks up the anti-oxidants, helping to keep the integrity of genes and proteins [intact], few had considered that simply boosting the amount of JNK could have such a broad impact on life span. ... JNK targets the same protein as the widely studied insulin receptor, central to human health and to the disease process that underlies diabetes ... We're learning that an organism's life span may not be limited by design. It was once thought that people and other organisms could simply live only a certain number of years and that's it. Instead, our genes play a crucial role in determining and adjusting how long we live. Can we control this process more fully?"
