domain-b.com : Tasmanian devils evolve to resist deadly cancer
Tasmanian devils are evolving in response to a highly lethal and contagious form of cancer, a Washington State University (WSU) researcher has found.A Tasmanian devil Andrew Storfer, WSU professor of biology, and an international team of scientists discovered that two regions in the genomes of Australia's iconic marsupials are changing in response to the rapid spread of devil facial tumor disease (DFTD), a nearly 100 percent fatal and transmissible cancer first detected in 1996.The work, published in Nature Communications, suggests some Tasmanian devil populations are evolving genetic resistance to DFTD that could help the species avoid extinction.Additionally, the genomic data will support future medical research exploring how animals evolve rapidly in response to cancer and other pathogens.

A deadly, infectious facial cancer has decimated Tasmanian devil populations and is driving them toward extinction, but a new study suggests they are rapidly developing resistance to the disease.A comprehensive international study of the genomes of 294 devils before and after the virulent cancer came to light 20 years ago, revealed species-wide adaptations in seven genes in just four to six devil generations.Five of those genes are linked to immunity and cancer resistance in mammals, according to the international study, published August 30 in the journal Nature Communications."The devils are evolving," study co-author Andrew Storfer of Washington State University told AFP.
