Israeli scientists, discovering that increasing the supply of a certain protein in mice led to raising their life expectancy by 23% and reducing their susceptibility to cancer, are speculating that the same effect may be found on humans.
The scientists note in the abstract to their peer-reviewed research, “Aging leads to a gradual decline in physical activity and disrupted energy homeostasis. The NAD+-dependent SIRT6 deacylase regulates aging and metabolism through mechanisms that largely remain unknown. Here, we show that SIRT6 overexpression leads to a reduction in frailty and lifespan extension in both male and female B6 mice. … These findings show that SIRT6 optimizes energy homeostasis in old age to delay frailty and preserve healthy aging.”
One of the authors of the study, which was published in Nature Communications, Prof. Haim Cohen of Bar-Ilan University, theorized, “The change in life expectancy is significant, when you consider that an equivalent jump in human life expectancy would have us living on average until
