The naked mole rat, a hairless African rodent with a long life-span and resistance to tumors, may hold clues to countering cancer and age-related ailments in people, said scientists who have mapped the creature’s genome. A first analysis of the naked mole rat’s genome has already revealed insights into its longevity, and that it split from its mice and rat cousins about 73 million years ago, according to the research published today in the journal Nature.

Unlike the mouse, the naked mole rat can live 10 times longer, or more than 30 years. While 95 percent of mice die from cancer, the naked mole rat is impervious to the disease, said Andrei Seluanov, a researcher at the University of Rochester who studies the rodents. The unusual traits of the creature, which lives in large ant-like colonies with a single breeding female or queen, together with its genomic information, offer newopportunities for understanding aging and other biological processes, the researchers said in the report. Continue to read: delawareonline.com
