Article Highlights
  • Discovery of Cellular Mechanisms Could Open Door to More Effective Anti-Aging Therapies
  • The increase in lifespan would be the equivalent of a human living for 400 or 500 years, according to one of the scientists.
  • The research draws on the discovery of two major pathways governing aging in C. elegans, which is a popular model in aging research because it shares many of its genes with humans and because its short lifespan of only three to four weeks allows scientists to quickly assess the effects of genetic and environmental interventions to extend healthy lifespan
  • Because these pathways are “conserved,” meaning that they have been passed down to humans through evolution, they have been the subject of intensive research. A number of drugs that extend healthy lifespan by altering these pathways are now under development. The discovery of the synergistic effect opens the door to even more effective anti-aging therapies.
  • “The synergistic extension is really wild,” said Rollins, who is the lead author with Jianfeng Lan, Ph.D., of Nanjing University. “The effect isn’t one plus one equals two, it’s one plus one equals five. Our findings demonstrate that nothing in nature exists in a vacuum; in order to develop the most effective anti-aging treatments we have to look at longevity networks rather than individual pathways.”
  • The discovery of the synergistic interaction could lead to the use of combination therapies, each affecting a different pathway, to extend healthy human lifespan in the same way that combination therapies are used to treat cancer and HIV
