Zebrafish may hold key to understanding human nerve cell development
Glia appear essential for 'hair cells'responsible for hearing and balance. Traditionally viewed as supportingactors, cells known as glia may be essential for the normal developmentof nerve cells responsible for hearing and balance, according to newUniversity of Utah research. The study is reported in the January 6,2005 issue of Neuron and is co-authored by scientists at the Universityof Was...Glow-in-the-dark zebrafish at UH hold keys to biological clocks
Using genetically altered zebrafish that glow in the dark, University of Houston researchers have found new tools that shed light upon biological clock cycles. Gregory M. Cahill, associate professor of biology and biochemistry at UH, and Maki Kaneko, a fellow UH researcher who is now at the University of California-San Diego, presented their findings in a paper titled "Light-dependent Dev...Temperature regulates circadian clock in zebrafish
The biological clock controls the circadian rhythms of a wide range of physiological and behavioral processes, from fluctuating hormone levels to sleep-wake cycles and feeding patterns. While it's well known that circadian clock elements sense and respond to light cycles, much less is known about how daily temperature cycles affect the clock's timing mechanism in vertebrates. In the open-access...Zebrafish may hold key to improved cancer research
A new study has confirmed that research done with zebrafish may be able to play a critical role in learning about the genetic basis of cancer and the mutations that can lead to it - and identified one gene in particular, B-myb, whose function is essential to preventing tumors. The findings were published in a professional journal, Proceedings of the National Academy of Sciences, by researc...Zebrafish Vitellogenin ELISA System from GE Healthcare, formerly Amersham Biosciences

Russell J. Buono and Paul J. Linser, Whitney MarineLaboratory, University of Florida, 9505 Ocean Shore Blvd.,St. Augustine, Florida 32086, 904-461-4000 The production of transgenic animals has proven to be a powerful tool in the study of developmentally regulated genes. The traditional method of microinjection of f...New Studies On Zebrafish Could Aid in Treating Birth Defects
In a new study published in the journal, Cell Metabolism, researchers have described the discovery of a mutation in the zebrafish that are remarkably similar to those observed// in children suffering from Menkes disease that could aid in finding new therapies for the disease. The finding has lead to the aquarium fish becoming an important animal model to better understand the diseas...Regrowth of Zebrafish's Tail Fin may Offer Clues for Treating Human Injuries
If a zebrafish loses a chunk of its tail fin, it’ll grow back within a week. //Like lizards, newts, and frogs, a zebrafish can replace surprisingly complex body parts. A tail fin, for example, has many different types of cells and is a very intricate structure. It is the fish version of an arm or leg. The question of how cold-blooded animals re-grow missing tails and other appendages h...Cocaine Exposure can Alter Neuronal Development in Zebrafish
Researchers from Boston University School of Medicine (BUSM) have shown that prenatal cocaine exposure in zebrafish (which share the majority of the same genes with humans) can alter neuronal development and acutely dysregulate the expression of circadian genes and those affecting melatonin signaling, growth and neurotransmission. The circadian factors, including the principal circadi...
