Salamander genome provides clues to the amphibian's regenerative abilities

Science
Dec. 22 (UPI) -- Scientists have for the first time sequenced the entire genome of the Iberian ribbed newt. Their efforts revealed a unique family of genes important to the salamander's impressive regenerative abilities.The Iberian ribbed newt, Pleurodeles waltl, maxes out at a foot in length, but the amphibian boasts a massive genome -- six times larger than the human genome.The sequencing of the giant genome by scientists at the Karolinska Institutet in Sweden revealed numerous copies of a microRNA group typically found in mammalian stem cells and tumor cells. Researchers believe this unique group is key to the salamander's ability to regenerate brain neurons and other parts of its body."It will be exciting to figure out how regeneration in the adult organism re-activates embryonic genes...
