Late-life semaglutide treatment slows ageing and extends lifespan in female mice

iNewsIndependentProgressive6 hr. ago

A study suggests that weight-loss medications Wegovy and Mounjaro, which contain the drug semaglutide, may have anti-ageing properties. Researchers observed that healthy mice given semaglutide lived 12% longer and showed reduced inflammation, DNA damage, and cellular aging markers compared to controls. The findings raise questions about whether these drugs could be repurposed as anti-ageing treatments, though current research focuses on overweight individuals and those with health conditions. The study's lead researcher, Professor Danica Chen, notes that the results align with findings from calorie restriction experiments, which are known to extend lifespan in smaller organisms.

A study published in Nature Medicine investigated the effects of semaglutide, a GLP-1 receptor agonist, on aging and lifespan in 20-month-old female mice. The research found that semaglutide treatment led to a significant reduction in food intake without affecting locomotor activity, respiratory exchange ratio, oxygen consumption, carbon dioxide production, or energy expenditure. The treatment also resulted in decreased body weight and tissue weight compared to the control group. The study suggests that semaglutide may act as a calorie restriction mimic, potentially slowing aging and extending lifespan. The findings build on previous research showing that GLP-1 medications have broad health benefits beyond glucose and weight management.

A study published in *Nature* reports that late-life treatment with the GLP-1 drug semaglutide in female mice extends their lifespan and improves physiological function by slowing aging processes. The research suggests this effect may go beyond simple calorie restriction. The findings were conducted on an inbred strain of laboratory mice and highlight potential therapeutic applications for age-related diseases. The study was led by researchers at the National Institute on Aging, NIH, and is part of ongoing investigations into the role of GLP-1 agonists in longevity. While the results are promising, further research is needed to determine if similar effects occur in humans.
