Limited cell-autonomous anticancer mechanisms in long-lived bats - Nature Communications

Cancer incidence is rare in long-lived bats. Here the authors find that although bat fibroblasts express telomerase and require only two oncogenic hits for malignant transformation, bats may rely on elevated p53 signaling and enhanced immunosurveillance to prevent cancer.

Several bat species live >20–40 years, suggesting that they possess efficient anti-aging and anti-cancer defenses.

We hypothesize that some bat species have evolved enhanced p53 activity as an additional anti-cancer strategy, similar to elephants. Further, the absence of unique cell-autonomous tumor suppressive mechanisms may suggest that in vivo bats may rely on enhanced immunosurveillance.
