People Who Live Beyond 105 Have Better DNA Repair

People who live beyond 105 years are more efficient at repairing DNA, according to a study published today in eLife.

Paolo Garagnani and colleagues, in collaboration with several research groups in Italy and a research team led by Patrick Descombes at Nestlé Research in Lausanne, Switzerland, recruited 81 semi-supercentenarians (those aged 105 years or older) and supercentenarians (those aged 110 years or older) from across the Italian peninsula. They compared these with 36 healthy people matched from the same region who were an average age of 68 years old.

They took blood samples from all the participants and conducted whole-genome sequencing to look for differences in the genes between the older and younger group. They then cross-checked their new results with genetic data from another previously published study which analyzed 333 Italian people aged over 100 years old and 358 people aged around 60 years old.
