(p. A3) Scientists are exploring a new biological link to longer life.
Boosting levels of an amino acid called taurine made mice and worms live longer, according to research published Thursday [June 7, 2023] in the journal Science. Middle-aged monkeys given taurine supplements became healthier, researchers said. In humans, lower levels of taurine were associated with age-related problems.
“This is a very promising molecule,” said Vijay Yadav, an assistant professor of genetics and development at Columbia University, who co-wrote the paper.
People have been searching for life-extending substances for millennia. Other recent studies have explored antiaging properties of compounds including resveratrol, found in red wine, and the immunosuppressive drug rapamycin. Yadav said he first suspected taurine’s connection with aging over a decade ago when his lab compared the contents of blood drawn from people of different ages.
. . .
Researchers gave daily doses of taurine to hundreds of 14-month-old mice, considered middle-aged, and compared their average lifespans to mice that didn’t get extra taurine. The female mice given taurine lived 12% longer on average and male mice that got taurine lived 10% longer, researchers said.
Mice that received taurine also appeared to be healthier.
