Toxic protein linked with aging and rare disease is triggered by short telomeres

A recent study has found that short, frayed telomeres in an individual are the cause for the production of a toxic protein which plays a role in aging. The protein, called progerin, is is also the cause of a rare genetic disease in children called progeria which causes aging at seven times the normal rate.  This suggests that aging may be a distinct biological mechanism triggered by factors such as short telomeres, and not just a wearing out of cells over time, as has been previously thought.
