Whale Protein Shows promise in Extending Lifespan, Boosting DNA Repair
ROCHESTER, NY – A protein found in bowhead whales is demonstrating a remarkable ability to enhance DNA repair, potentially unlocking new avenues for extending human lifespan and combating age-related diseases, according to research published in the journal Nature. Scientists at the University of Rochester have identified the protein, dubbed CIRBP, as a key factor in the whale’s remarkable longevity - reaching ages of up to 250 years.
CIRBP exhibits an remarkable accuracy in repairing damaged regions of DNA, explained lead researcher Professor Vera Gorbunova.”This mechanism explains why whales can live up to 250 years,” she stated.
Laboratory tests have shown that adding CIRBP to human cells significantly improves their DNA repair capabilities. Moreover, studies on fruit flies revealed a corresponding extension in lifespan. Experts believe these findings could pave the way for treatments designed to slow the aging process.
“This whale is like a superstar of longevity,” commented Dr. Alex Cagan, an evolutionary geneticist at the Wellcome Sanger Institute. “The findings are very captivating, need to be confirmed in other laboratories, but they are quite convincing.”
Researchers also note a potential link between the whales’ long lives and their polar habitat, observing that CIRBP levels increase even with minor temperature drops.
The research team is now preparing to test the protein – or drugs that can activate it - for it’s ability to safely improve DNA repair in small mammals, marking the next step in translating this discovery toward potential human applications.
