 Mutant Genes 
 Linked to Long Life 

DNA-protecting enzyme may be key to living to 100

Nov 16, 09 8:43 AM CST
(Newser) - Scientists have spotted a link among people who live to age 100: high levels of telomerase, an enzyme that protects DNA and could possibly be simulated in life-lengthening drugs. The enzyme repairs telomeres, end sections of DNA that have been likened to plastic tips that prevent shoelaces from unraveling. In... More »

Scientists Link Gene Mutation to Longevity

Alteration makes cells less receptive to
growth factor

Mar 5, 08 11:42 AM CST
(Newser) - A genetic mutation that makes cells less responsive to growth hormone has been linked to human longevity, Scientific American reports. A recent study looked at children of Ashkenazi Jews with a family history of long life and an average age of 98, and compared their genes with the children of... More »
