2008 National DNA Day Online Chatroom Transcript

This is just one question from an archive of the National DNA Day Moderated Chat held in April 2008. The NHGRI Director and many genomics experts from across NHGRI took questions from students, teachers and the general public on topics ranging from basic genomic research, to the genetic basis of disease, to ethical questions about genetic privacy.

Scientists think that stopping the shortening of telomeres would end aging in humans. Is this too simplistic to become reality?
     Faith Pangilinan, Ph.D.: Looking for genetic risk factors for human birth defects (mainly spina bifida). Although it's been seen that the shortening of telomeres are associated with aging, it hasn't been shown that it causes aging. So even if we could figure out the considerable challenge of how to stop telomere shortening, there's no guarantee it would stop aging.
