As people at the [National Institute on Aging] keep saying to me, 'It's not that people in program management don't think it's a really exciting project, but the reviewers don't like the fact that you're critiquing the studies that they've done in mice. The DNA repair transcriptomes of the liver of humans, naked mole rats and mice were compared.

Even if all this could be accomplished—and keep in mind that it's been done in only a handful of species—the production of such animals would be painfully sluggish. There are no major threats to Damaraland mole-rats.

Compared with other rodents, naked mole rats live extremely long lives 20 y and more.
