Chinese scientists have identified a gene1 playing an important role in regulating the development and lifespan of primates2 through genome-editing technology and experiments on monkeys and human stem cells.
 
中國科學家通過基因組編輯技術以及在猴子和人類干細胞實驗的基礎上發現一個基因,這個基因對于調節靈長類的發育以及壽命起著重要作用。
 
The study may open the door to new research on human development and aging, as well as new treatments for age-related disorders3, said Liu Guanghui, a professor at the Institute of Biophysics of the Chinese Academy of Sciences (CAS).
 
Understanding the genetic4 basis of aging is the prerequisite5 to delaying aging and treating age-related illnesses, Liu said.
 
In 1999, scientists found that the Sir2 gene plays a role in prolonging the lifespan of Saccharomyces cerevisiae, a kind of yeast6. Then scientists found that the SIRT6 gene, a homologue of Sir2, is involved in the regulation of aging and longevity7 in rodents8.
 
Deficiency of SIRT6 from mice leads to features of accelerated aging such as loss of subcutaneous fat, spinal9 curvature, colitis and shortening of telomere.
 
However, the biological function of SIRT6 in primates remains10 largely unknown.
