Rapamycin: Limited anti-aging effects
Date:7/25/2013

ted rapamycin's effects on different age groups. This enabled us to examine whether the possible effects of rapamycin depend on the age at which treatment started."

The animals were genetically identical twin mice. All of the animals received rapamycin regularly over a period of approximately one year. For each age cohort there was also a control group, which did not take the substance.

Need for comprehensive analyses

"Generally speaking, our studies show that a number of different parameters have to be considered when assessing the efficacy of possible anti-aging interventions. The interpretation of the data depends heavily on the overall picture of findings. Lifespan measures alone are not a reliable indicator of anti-aging effects," emphasises Ehninger. "This makes the search for anti-aging medicines tedious, but it is also very promising, because such substances could open up new possibilities for medicine. However, this is still some way off."
