Genetically modifying adult mice to express all seven human sirtuin genes can be done quickly using viral vectors.

“we have now actually have some early data I don't want to scoop myself but we're able to know genetically modified adult mice with a V the virus a 1000 C 8 a virus and we can now genetically change a mouse so we've just put in all seven sort own genes into it not into mice in old mice you've put the seven human cert genes into mice Oh seven else gentle Mouse but that sort of experiment would have taken a decade to do just a few years ago but now that we can deliver genes we can do very quickly”
