A bowhead whale's DNA offers clues to fight cancer
The article explores how the DNA of bowhead whales provides insights into cancer prevention. It highlights Peto's paradox, where large, long-lived animals paradoxically have low cancer rates. Researchers, led by Vera Gorbunova, found that bowhead whales produce a high amount of the CIRBP protein, which efficiently repairs DNA damage, thus preventing cancer-causing mutations. This 'maintenance' approach contrasts with elephants' strategy of having multiple copies of the p53 tumor suppressor gene to eliminate abnormal cells. Scientists hope that studying these longevity mechanisms in whales could inform the development of new human cancer therapies.
Note
the article calls out the most important and unfortunately, unanswered question: what are the tradeoffs to the longevity inducing pathways in elephants and whales?
perhaps a more complete picture could help us understand why humans didn't development them and how we could co-opt them.
