DNA sequencing for eels

It should come as no surprise to anyone that research using animals has generated a wealth of knowledge used to better understand human biology and behavior and improve medical treatments. It may be shocking to learn that biologists are hoping electric eels will provide insight into the human nervous system.

This article on the journal Nature’s Web site explains why researchers are asking for the DNA of eels to be thoroughly sequenced by sequencers who have already completed similar studies on mice and chimps.

One of the things that sequencing the E. electricus genome could lead to, is advances in treatments for spinal injuries, the researchers say. The fish have developed an amazing ability to regenerate, possibly as a result of often having their tails bitten off by electro-sensing predatory catfish, says Albert.

“You can cut off the back third of the body and they will regenerate everything, including the spinal cord,” says Albert.

It will be interesting to see what is learned from this type of research using animals as models.
