Naked mole-rats bear lifesaving clues

"Imagine 200 mice living in a shoe box buried four feet under the ground -- things are going to get bad fast," he said.

The researchers think they have identified a novel mechanism for protecting the adult brain in times of oxygen deprivation.

"Developing this target into a clinical application is our next goal," he said. "We need to find a way to rapidly up-regulate the infant-type of calcium channels. Adult humans actually have some of these channels already, but far fewer than infants."

Park, who for years has studied naked mole-rats and their unusual adaptations, thinks the latest findings "are just the tip of the iceberg" of what we can learn from the rodents. Their homes are not only oxygen-poor, but rich in carbon dioxide and ammonia -- conditions that would make most animals ill. Yet mole-rats have evolved to suppress pain and even cancer.

"The more we study these creatures," said Park, "the more we learn."
