Scientists have found a molecule that will help restore cartilage and muscles in the future
Scientists have discovered micro-RNA molecules that are responsible for the regeneration of the tip of the lizard's tail. Researchers believe that these RNA fragments may help a person to repair cartilage, muscles and spine in the future. The work of Hutchins et al. A differential expression of preserved and novel microRNAs during tail regeneration in the lizard Anolis carolinensis is published in the journal BMC Genomics.
If you grab a lizard by the tail, it will leave it in your hands, and then grow a new one. Until now, scientists have not been reliably known exactly how the lizard's tail regenerates.
Scientists from the Institute of Genomic Research and the University of Arizona found three previously unknown micro-RNA molecules in an Anolis carolinensis lizard. Researchers believe that they play a big role in regeneration.
Earlier, a team of scientists from the University of Arizona has already identified hundreds of genes involved in the regeneration process in a lizard. "We are very excited to have found these micro-RNAs, and now we can study them in detail. After all, micro-RNAs are able to control a large number of genes, as an orchestra conductor watches the musicians play," comments one of the authors of the work, Kenro Kusumi (in a press release TGen–ASU researchers find tiny genetic switches in lizard tail regeneration – VM). In the future, the discovery of scientists, together with their six-year research, can help develop approaches for the "inclusion" of regeneration genes in the human body.
Elizabeth Hutchins, the lead author of the paper, hopes that eventually this research will help create regenerating knee cartilage, restore the spine of accident victims or help injured war veterans.
