Want to live into your 100 ? If you ’re young and fertile , you have to decide now whether you want to take a drug that will extend your life by a few decades .
Researchers at Stanford Medical School have chance upon that stop the activity of certain genes can prolong the lives of roundworms by up to 30 percent – but only if the worms are fertile . This is further confirmation of what many scientists had already suspected , which is that the headstone to life extension is attach to the procreative arrangement . Geneticist Anne Brunet , Centennial State - source on the new sketch , excuse :
It make a sort of good sense that the reproductive system would be call for in life span , since that is really the only ‘ immortal ’ part of an organism . In that context , the body is just the mortal gasbag .
She and a squad of scientists come upon that tinea survive longer if they block the action of several different cistron , most notably a gene called Ash-2 . This gene is special because it regulates how other genes get express – it ’s a variety of master - switching factor . When Ash-2 is silenced , several genes relate to the germline – jail cell used for reproduction – remain silent too . And somehow this extends life .
Bunet added :
We still do n’t know precisely how this go mechanistically , but we ’ve show that the presence of the germline is absolutely substantive for this length of service extension to go on .
In other actor’s line : As long as you ’re still fertile , with a functioning germline , exclude down Ash-2 might help you live longer . If you ’re a worm . But there is enough overlap between human and worm DNA that this could provide a key to monkey with human lifespans too .
