Scientists have suspected that spare parts in the genome"”extra copies of functional genes that arise when genes or whole genomes get duplicated"”might sometimes provide the raw materials for the evolution of new traits. Now, researchers report in a study published online on September 3rd in Current Biology, a Cell Press publication, that they have discovered a prime example of this in fish. The researchers show that a duplicate copy of a gene involved in embryonic development has...

Michigan State University researchers say they have created an improved zebra fish cloning method in a study that might further human health research. A team of scientists say their new and more efficient way of cloning zebra fish is important because zebra fish are becoming the animal of choice for many researchers. After the mouse, it is the most commonly used vertebrate in genetic studies, said Professor Jose Cibelli, who led the study. It is used in cancer research and cardiovascular...

A team of Michigan State University researchers has developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research. The work of the MSU researchers, detailed in the recent issue of the journal Nature Methods, is important because zebra fish, small striped fish common to many aquariums, are quickly becoming the animal of choice for many researchers. "After the mouse, it is the most commonly used vertebrate in genetic studies,"...

When you were a kid your mom poured it on your scraped finger to stave off infection. When you got older you might have even used it to bleach your hair. Now there's another possible function for this over-the-counter colorless liquid: your body might be using hydrogen peroxide as an envoy that marshals troops of healing cells to wounded tissue.Using the zebrafish as an animal model, researchers in the lab of Harvard Medical School professor of systems biology Timothy Mitchison and Dana...

The pigmented cells in zebrafish help scientists tease out how oncogenes that are know to contribute to cancer, influence the formation and regulation of the aggressive human skin cancer, melanoma In a new study published in Disease Models & Mechanisms, scientists use the zebrafish to gain insight into the influence of known cancer genes on the development and progression of melanoma, an aggressive form of human skin cancer with limited treatment options. Inside the cell, signals are...

U.S. medical scientists say their discovery that an embryo's heartbeat drives blood cell formation might lead to new treatments for blood diseases. Biologists have long wondered why the embryonic heart begins beating so early, before tissues actually need to be infused with blood. Now two groups of researchers from Children's Hospital Boston, Brigham and Women's Hospital and the Harvard Stem Cell Institute say they have the answer. Using multiple lines of evidence from zebrafish, mice and...

A recent study reveals evidence that blood cells of an embryo grow only under conditions of pressure by a beating heart, Reuters reported.  The results make clear why an embryo's heart begins palpitating in the first weeks of conception, and additionally facilitates support for new stem cell-based treatments for numerous blood disorders including leukemia.  Dr. George Daley of Harvard Medical School and Children's Hospital Boston said, "In learning how the heartbeat stimulates...

Clues about how blood forms could yield new strategies for treating blood diseases Biologists have long wondered why the embryonic heart begins beating so early, before the tissues actually need to be infused with blood. Two groups of researchers from Children's Hospital Boston, Brigham and Women's Hospital, and the Harvard Stem Cell Institute (HSCI) -"“ presenting multiple lines of evidence from zebrafish, mice and mouse embryonic stem cells -"“ provide an intriguing answer: A...

Blood stem cells literally go with the flow, according to a new report published as an immediate early publication in the journal Cell, a Cell Press journal, on May 13th. Researchers have found that a heart beat and blood circulation are critical signals for the production of blood-forming, or hematopoietic, stem cells in the developing embryo. The evidence found in zebrafish and mice may lead to new methods to coax embryonic stem cell-like cells (known as induced pluripotent stem cells or...

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...
