Among zebrafish, the eyes have it. Inside them is a mosaic of light-sensitive cells whose structure and functions are nearly identical to those of humans. There, biologists at The Florida State University discovered a gene mutation that determines if the cells develop as rods (the photoreceptors responsible for dim-light vision) or as cones (the photoreceptors needed for color vision). Described in a paper published in the Proceedings of the National Academy of Sciences (PNAS), the landmark...

Researchers in California are using young zebrafish to study the effects of excess cholesterol on arteries. Young zebrafish are transparent, allowing scientists at the University of California, San Diego, School of Medicine to view the development of plaques in blood vessels, the university reported. Dr. Yury I. Miller, associate professor of medicine, said the zebrafish model is a promising method for screening new heart drugs. Because zebrafish are transparent for the first 30 days of life,...

Researchers say they may have discovered the way a particular gene regulates the development of tumors.The p53 gene, also known as tumor protein 53, acts as a tumor suppressor in guarding against cancer. In half of all cancers the gene is either damaged or inactive, which allows damaged cells to form tumors, scientists said. Scientists in Singapore and the University of Dundee used zebrafish for their study, because they also carry the same p53 gene as humans. They used a method that caused...

NEW ROCHELLE, N.Y., Dec. 29 /PRNewswire/ -- The emerging field of nutrigenomics, which aims to identify the genetic factors that influence the body's response to diet and studies how the bioactive constituents of food affect gene expression, is explored in a series of provocative, interdisciplinary reports and analyses in the December 2008 Special Issue (Volume 12, number 4) of OMICS: A Journal of Integrative Biology, a peer-reviewed journal published by Mary Ann Liebert, Inc....

A study of zebrafish has revealed ways to potentially slow or prevent the onset of cancerous tumors, the Huntsman Cancer Institute in Utah says. Using zebrafish that share genetics similar to humans, researchers discovered two enzymes that, when combined, could be involved in the earliest stages of cancer, the Salt Lake City-based Institute announced Wednesday. Genetically manipulating the enzymes could lead to therapies that target tumors in their earliest stage, said David Jones, a senior...

Cellular reprogramming heads the journal's list of the Top Ten Scientific Advances of 2008In its annual list of the year's top ten scientific breakthroughs, the journal Science has given top honors to research that produced "made-to-order" cell lines by reprogramming cells from ill patients. These cell lines, and the techniques for producing them, offer long-sought tools for understanding -- and hopefully someday curing -- difficult-to-study diseases such as Parkinson's disease and type 1...

A University of Iowa-led international research team has found a new gene associated with the brain disorder epilepsy. While the PRICKLE1 gene mutation was specific to a rare form of epilepsy, the study results could help lead to new ideas for overall epilepsy treatment. The findings, which involved nearly two dozen institutions from six different countries, appear in the Nov. 7 issue of the American Journal of Human Genetics. In epilepsy, nerve cells in the brain signal abnormally and cause...

The first few hours of an embryo developing were caught with the help of a new high-powered microscope. The event marked the first time scientists could catch this process in vertebrates, and watched a zebrafish develop from a single cell into an embryo with a beating heart.  Researchers created a three-dimensional digital reconstruction of the tiny, developing fish known as zebra danio. They are popular research subjects because they are cheaper to breed than mice and share...

The Giant Danio (Devario aequipinnatus) is a tropical fish belonging to the minnow family (Cyprinidae). Originating in Sri Lanka, Nepal, and the West coast of India, it grows to a maximum length of 6 in (15 cm), making it one of the largest of the Danionins. They are characterized by a blue and yellow torpedo shaped body with gray and clear fins. In the wild, Giant Danios live in clear streams and rivers among hills at elevations up to 1000 ft (300 m) above sea level. Their native...

The Zebrafish (Danio rerio) is a tropical fish belonging to the minnow family (Cyprinidae). It is a popular aquarium fish, where it is frequently sold under the trade name Zebra danio, and is also an important model organism. Characteristics The zebrafish arose in the Ganges region in Eastern India and is also native to Pakistan, Bangladesh, Nepal and Myanmar. It commonly inhabits streams, canals, ditches, ponds and slow-moving to stagnant water bodies, including rice fields. The...

The Glowlight danio is a small fish with a maximum length of 1.25 in (4 cm). Its coloration is brown, yellow, green and red. The Glowlight can live in waters that are (20-25 degrees Celsius), 6 to 7 pH, with a soft to medium hardness and a low to medium salinity. These fish are compatible with other danios and typically live from 1 to 3 years. They are moderately difficult fish to keep, and breeding can be even harder. Danio choprai or the Glowlight danio is a small, schooling fish...
