Blocking One Enzyme Extended Lifespan in Aging Mice by 17%

A new study in mice has found that inhibiting a single enzyme can extend lifespan by up to 17% and improve multiple aspects of health in old age. The enzyme, called DYRK1A, is known to be involved in cell proliferation and brain development, but its role in aging was less clear. Researchers used a drug-like molecule to block DYRK1A in aged mice and observed not only longer lives but also better motor function, grip strength, and memory compared to untreated animals. The treated mice also had less inflammation and healthier tissues. While the findings are promising, the study is preliminary and has not yet been tested in humans. The team hopes that targeting DYRK1A could one day lead to therapies for age-related diseases, but more research is needed to confirm safety and efficacy.
