TGen-ASU researchers find tiny genetic switches in lizard tail regeneration

09.05.2016

Findings from lizards may impact future therapies to regrow organs in humans

Any kid who pulls on a lizard tail knows it can drop off to avoid capture, but how they regrow a new tail remains a mystery. Now, researchers at the Translational Genomics Research Institute (TGen) and Arizona State University (ASU) have identified tiny RNA switches, known as microRNAs, which may hold the keys to regenerating muscles, cartilage and spinal columns.


In a study published today in the scientific journal BMC Genomics, ASU and TGen scientists for the first time identified three microRNA's -- a which turn genes on and off -- that are associated with the regeneration of tails in the green anole lizard, Anolis carolinensis.

In a study published today in the scientific journal BMC Genomics, ASU and TGen scientists for the first time identified three microRNAs -- which turn genes on and off -- that are associated with the regeneration of tails in the green anole lizard, Anolis carolinensis.

Using next-generation genomic and computer analysis, this interdisciplinary team of scientists hope their findings, following nearly 6 years of research, will help lead to discoveries of new therapeutic approaches to switch on regeneration genes in humans.

"Since microRNAs are able to control a large number of genes at the same time, like an orchestra conductor leading the musicians, we hypothesized that they had to play a role in regeneration," said senior author Dr. Kenro Kusumi, a Professor in ASU's School of Life Sciences and Associate Dean in the College of Liberal Arts and Sciences, and an adjunct faculty member at TGen. "Our earlier work found that hundreds of genes are involved in regeneration, and we are very excited to study these three new microRNAs."

Dr. Elizabeth Hutchins, a Post-Doctoral Fellow in TGen's Neurogenomics Division, and co-lead author of the study, said she hopes this investigation eventually enables such things as regenerating cartilage in knees, repairing spinal cords in accident victims, and reproducing the muscles of injured war veterans.

"It is the translational nature of this work -- how it could eventually be applied to people -- that led to my interest in this study," said Dr. Hutchins, who graduated from ASU's Molecular and Cellular Biology Program. "For example, we currently don't have the ability to regrow knee cartilage, which would really help someone like my grandmother."

"This work highlights the importance of tiny RNA molecules in the tissue regeneration process, and showed for the first time an asymmetric microRNA distribution in different portions of the regenerating lizard tails," said Dr. Marco Mangone, a co-author and Assistant Professor with ASU's School of Life Sciences and Biodesign Institute. "It seems like microRNAs may play an active role in this process, and are potentially able to shape the regenerating lizard tail like playdough."

The research team also included: Dr. Justin Wolter of ASU's Biodesign Institute and School of Life Sciences; and Dr. Walter Eckalbar at the University of California, San Francisco.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
