Researchers have finally had the chance to map the genome of the Tasmanian Devil. This is the first time that researchers were given this opportunity which is also a crucial step in understanding tumuors and how it can relate to human cancer. Recently, Devil populations have been hit hard by the spread of the transmissible facial tumours.

Dr. Janine Deakin from the Research School of Biology at The Australian National University led the international team for this research and their research is published in this month's edition of PLoS Genetics. In this research, the genome from a normal Tasmanian Devil was compared to the Devils with facial tumours. Based on the comparison, the researchers found out that significant fragment of the chromosomes were jumbled, akin to a jigsaw puzzle done the wrong way.

The first case of devil facial tumour disease was recorded in 1996. While Devils can die from the cancer, thousands more have died through starvation, as the disease deforms their faces so badly that they can't eat. The aggressive carnivores contract the cancer through biting and jaw wrestling with Devils that are already infected.

Deakin's team found that, surprisingly, the Devil tumour is evolving very slowly and has changed very little since its emergence 16 years ago.

"That's really unusual for cancers because usually, for human cancers, evolution is rapid and the tumour will be completely different between the original tumour and its metastases. In this work we confirmed that the devil tumour is genetically very stable," Deakin said.

Researchers hope that by unlocking the secrets of this slowly evolving cancer they will understand not only the Devil tumour, but also the way human cancers develop.

"In humans, you are usually working with a rapidly evolving cancer and it's hard to identify the important things because it's all happening so fast. The Devil is going to be a good model for looking at some human cancers because it is so stable - with everything happening slower we have a better chance of finding those things out," she said.

The Tasmanian Devil has recently been listed as an endangered animal and it's predicted to become extinct in 25 to 35 years unless a cure can be found.
