Why do naked mole rats live long, cancer-free lives?
Rochester biologists were surprised to see that despite its remarkable longevity, the naked mole rat still has cells that undergo senescence, like the cells in much shorter-lived mice.
An extra protein gives naked mole rats more power to stop cancer
Naked mole rats are small, hairless, subterranean rodents that have never been known to get cancer despite having a 30-year lifespan. A new protein discovered by biologist Vera Gorbunova may help explain why.
Vertebrate of the Year!
“Here at the University, the naked mole rat seems like it has been the Vertebrate of the Year for several years,” said President Seligman.
Naked Mole Rats Cancer-resistant Chemical ID’d
The biologists’ focus on high molecular weight hyaluronan (HMW-HA) began after they noticed that a gooey substance in the naked mole rat culture was clogging the vacuum pumps and tubing.
How Do Blind Mole Rats Ward Off Cancer?
Blind mole rats and naked mole rats—both subterranean rodents with long life spans—are the only mammals never known to develop cancer. Rochester biologists have now determined that the mechanism for fighting off cancer differs between the two.
