An extra protein gives naked mole rats more power to stop cancer

A protein newly found in the naked mole rat may help explain its unique ability to ward off cancer. The protein is associated with a locus that is also found in humans and mice. It's the job of that locus to encode several cancer-fighting proteins. The locus found in naked mole rats encodes a total of four cancer-fighting proteins, while the human and mouse version encodes only three.

Biologists determine how blind mole rats fight off cancer

In continuation of my update on mole rats..

Biologists at the University of Rochester have determined how blind mole rats fight off cancer-and the mechanism differs from what they discovered three years ago in another long-lived and cancer-resistant mole rat species, the naked mole rat.

The team of researchers, led by Professor Vera Gorbunova and Assistant Professor Andrei Seluanov, found that abnormally growing cells in blind mole rats secrete the interferon beta protein, which causes those cells to rapidly die. Seluanov and Gorbunova hope the discovery will eventually help lead to new cancer therapies in humans. Their findings are being published this week in the Proceedings of the National Academy of Sciences.

Blind mole rats and naked mole rats-both subterranean rodents with long life spans-are the only mammals never known to develop cancer. Three years ago, Seluanov and Gorbunova determined the anti-cancer mechanism in the naked mole rat. Their research found that a specific gene-p16-makes the cancerous cells in naked mole rats hypersensitive to overcrowding, and stops them from proliferating when too many crowd together.

"We expected blind mole rats to have a similar mechanism for stopping the spread of cancerous cells," said Seluanov. "Instead, we discovered they've evolved their own mechanism."

Scientists identify why African naked mole-rat feels no pain when exposed to acid

In continuation of my update  naked mole-rat

Scientists identify why African naked mole-rat feels no pain when exposed to acid: British researchers of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have found out why the African naked mole-rat (Heterocephalus glaber), one of the world's most unusual mammals, feels no pain when exposed to acid.

Scientists Discover Gene that 'Cancer-Proofs' Rodent's Cells

In my earlier blog, I did mention about how naked mole rats may help cure cancer. The same researchers have achieved something interesting i.e., they have discovered have discovered the gene that "cancer-proofs the naked mole". For details...
