Researchers confirmed on Wednesday (August 26) that endangered little brown bats can adapt to cancer-causing cell damage in a unique pattern that could inform efforts to curb the disease that claims the lives of more than 600,000 Americans annually. The findings came after an experiment using tissue samples from the creatures disclosed that the interaction led to the genes that promoted cell death instead of DNA repair when the bats’ cells were tested against lethal chemicals. “We found the literal opposite of what we expected if you treat the bats with a lethal dose of this chemical,” biologist Juan Manuel “Manny” Vazquez, an assistant professor at Penn State University and co-lead author of the related study, confirmed in a news release from the University of California, Berkeley. “The longest-lived bat in North America decides ‘I can't save this ship’ and immediately switches gears to prioritise killing off the cells that are damaged. The elephant, another cancer-resistant species that is long-lived, has the exact same strategy: if you can't save the cell, kill the cell,” he continued. The University of Vermont confirmed that analysis of the bats’ DNA revealed another secret to their longevity and good immune function.<h3>Multiple copies of immune gene</h3>The scientists have found that the animals had multiple copies of an immune gene discovered in every mammal, known as “protein kinase r,” or PRK. Generally, Mammals have one copy of the gene, suggesting to Vazquez it could be responsible for protective effects. The study’s authors also assert that the findings could be applied to human research on longevity and disease. “We can look at these bats and try to understand how, in the same way you can improve your immune system to fight off viruses, maybe you can improve your immune system so it doesn't decline in old age,” Vazquez said. “Or maybe bats can help us find ways to fight off tumours so our immune system doesn’t get tired, and that can also help us deal with other stresses of life and not exhaust our immunity.”&nbsp;Also read: <a href="https://www.wionews.com/trending/whose-buffalo-is-it-bihar-police-turn-to-dna-test-to-solve-ownership-row-1787800004479">The great buffalo mystery: Bihar Police seek DNA proof to find its real owner</a> Elise Lauterbur, an assistant professor of evolutionary biology at the University of Vermont and co-lead author of the study, explained, "Pathogen adaptation, longevity and cancer resistance- they are fundamentally linked.” That said, applying these adaptations to treat human disease remains a distant prospect. So why study bats in the first place? For their size, they're remarkably long-lived among mammals, with some species surviving for decades. (Little brown bats face endangerment mainly due to white-nose syndrome, a lethal fungal disease.) Bats also lead highly active lives, flying nightly to hunt insects. Researchers suggest this level of fitness may contribute to stronger immune function and longer lifespan — a pattern also seen in humans. “Bats have evolved this incredible fitness capacity, this incredible ability to deal with disease and this incredible ability to be able to prevent cancer,” Vazquez said. “That means that, by understanding how bats have evolved to do all these things that other mammals haven't, we can find completely new and unexpected ways of dealing with the normal things that cause human diseases.”
