Making Blind Zebrafish See

01.07.2004


Scientists in the Conway Institute of Biomolecular & Biomedical Research have restored the sight of blind zebrafish whose eyes failed to develop due to a genetic mutation. The findings, published this week in Developmental Biology, are exciting first steps on a long road to understanding eye diseases in humans.



Dr. Breandan Kennedy and his colleagues at the University of Washington, Seattle and the Hubrecht Laboratory in Utrecht, Netherlands first identified a family of eyeless fish. They then discovered the gene that controls initial development of eye tissue (retinal homeobox 3 or rx3) and that mutations in this gene resulted in the eyeless fish.

When Dr. Kennedy and his research team introduced a normal copy of the rx3 gene into fish embryos that had inherited the mutated version of the gene, they discovered that this treatment restored normal eye development. Recent studies from researchers in the Unites States have shown that mutations in the human form of this gene cause anophthalmia, a disease in which eyes also fail to form.


Commenting on the findings, Dr. Kennedy said, “the sequencing of the human genome has given us the blueprint of life. However, we now need to determine the role of each of the ~30,000 genes in the genome, and their links to disease. Zebrafish provide an excellent system for this goal, as they are particularly suited to genetic studies and because many genes perform the same task in zebrafish and humans.”

This is the first publication from the largest Irish facility for the study of zebrafish, which was established last year after the opening of the Conway Institute in University College Dublin. These tiny, freshwater fish have many genetic traits that are similar to humans due to the fact that they also possess a backbone. This makes them ideal models for the study of inherited human diseases.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
