What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new research suggests that multiple cell types are needed to regrow the complete organ, at least in zebrafish. Researchers at Washington University School of Medicine in St. Louis have shown that cells capable of regenerating a zebrafish fin do not revert to stem cells that can form any tissue....

Genes predict worst-case scenario Leukemia is the most common childhood cancer; it also occurs in adults. Now researchers working with zebrafish at Huntsman Cancer Institute (HCI) at the University of Utah have identified previously undiscovered high-risk genetic features in T-cell acute lymphocytic leukemia (T-ALL), according to an article published online May 9, 2011, in the cancer research journal Oncogene. When compared to samples from human patients with T-ALL, these genetic...

A common, tiny tropical fish plays a key role in a new model for Cushing disease, giving researchers a powerful tool to conduct extensive searches for effective treatments for this serious hormonal disorder, testing up to 300 drugs weekly. The model "“ published online on May 2 by the Proceedings of the National Academy of Sciences -- was created in the laboratory of Shlomo Melmed, MD, dean of the medical faculty at Cedars-Sinai Medical Center, by his research team led by Ning-Ai Liu,...

Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods. The work could help shed light on health-related problems such as how cancerous cells spread, what makes some people more prone to heart attacks, (http://www.mayoclinic.org/heart-attack/) or how...

Innovative development offers new platform for large-scale drug screening Working with a group of national and international researchers, scientists from the Florida campus of The Scripps Research Institute have developed a new genetic model of premature aging disorders that could shed light on these rare conditions in humans and provide a novel platform for large-scale screening of compounds to combat these and other age-related diseases. In the new study, which was published this month in...

Discovery suggests new drug targets and markers to help treat the aggressive, deadly skin cancer Thanks to the zebrafish, there is new hope for people with melanoma, an aggressive skin cancer that is responsible for approximately 8,700 deaths each year in the United States. In a study that was published in the March 24th issue of the journal Nature, and featured on the cover, researchers identified SETDB1 as a new gene that promotes the growth of melanoma and may play a role in up to 70...

Research being presented today (01 April) at the UK National Stem Cell Network annual science conference provides another piece in the puzzle of why it can be so hard to produce large numbers of the same type of cell in the lab "“ a process that is vital for scaling up stem cell production for therapeutic use. This knowledge will help researchers to develop strategies for obtaining the desired cell type for use in either research or medicine. The work will be presented by Dr Robert...

(Ivanhoe Newswire) -- Scientists have discovered a more effective alternative to skin whitening creams, and it comes from an ancient Chinese herb. Skin whitening is popular in countries like China, Japan, Korea and India, where many women view whiter skin as a symbol of beauty, good health and high social status. According to one study, about half the women in Asian countries use lightening creams. This adds up to billions of dollars a year. Many whitening creams and lotions contain...

Zebrafish study highlights existing drugs that may help restore muscle in DMD BOSTON, March 18, 2011 /PRNewswire-USNewswire/ -- Armed with a zebrafish model of Duchenne muscular dystrophy (DMD) and a library of 1,200 chemicals already approved for human use, researchers at Children's Hospital Boston have identified a compound that reverses the loss of muscle structure and function associated with DMD, seemingly by compensating for the loss of a critical protein. The discovery, published...

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...
