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.
