We think that weve possibly found regulators of aging. Lifespan of Groups of Mice With Different Levels of Caloric Reduction In 2003 Sinclairs lab published a paper in Nature that 25 described the discovery of a gene that switched on in the yeast cell in response to calorie restriction, which Sinclair calls a master regulator in aging. Since then, his team has been searching for an analogous gene that plays a similar role in the mammalian cell.
