Kim Bland, Ph.D., Stowers Institute for Medical Research Sea lamprey studies show remarkably conserved gene expression patterns in jawless versus jawed vertebrates If you never understood what “ontogeny recapitulates phylogeny” meant in high school, don’t worry: biologists no longer think that an animal’s “ontogeny”, that is, its embryonic development, replays its entire evolutionary history. Instead, the new way to figure out how animals evolved is to compare regulatory...

beating heart of a zebrafish embryo
2014-07-25 02:45:59

Max-Planck-Gesellschaft, München Researchers of the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden report how they managed to capture detailed three-dimensional images of cardiac dynamics in zebrafish. The novel approach: They combine high-speed Selective Plane Illumination Microscopy (SPIM) and clever image processing to reconstruct multi-view movie stacks of the beating heart. Furthermore, they have developed a method of generating high-resolution static...

Society for Experimental Biology Austrian researchers have found that jetlag has severe effects on red blood cells, possibly explaining the high incidence of heart disease seen in shift workers. However, these effects can be counterbalanced by fresh, young red blood cells – making blood donations a potential therapy for shift workers. The scientists, led by Dr Margit Egg (University of Innsbruck), worked on zebrafish (Danio rerio), a model organism which, like humans, is active...

Alcohol And Zebrafish Help Understand Social Behavior
2014-05-14 08:50:39

April Flowers for redOrbit.com – Your Universe Online Alcohol consumption affects social behavior, as any college student can tell you. But does it have to have such an effect? A new study from New York University's (NYU) Polytechnic School of Engineering suggests that the complex interplay between alcohol and social behavior can be understood and the negative effects perhaps mitigated. Their groundbreaking experiments, described in the journal Alcohol: Clinical and Experimental...

Study Reveals Surprising Behavioral Changes that May Link to Leadership in this Species BROOKLYN, N.Y., May 13, 2014 /PRNewswire/ -- New findings published by researchers at the New York University Polytechnic School of Engineering are helping to unravel the complex interplay between alcohol and social behavior and may lead to new therapies for mitigating the negative impacts of alcohol use and abuse. Their experiments, published in the current issue of Alcohol: Clinical and...

redOrbit Staff & Wire Reports - Your Universe Online A newly-identified genetic association with facial asymmetry in ancient cavefish could shed new light into mysteries surrounding conditions such as cleft palate or hemifacial microsomia in humans, according to research appearing in a recent edition of the peer-reviewed journal Genetics. Joshua Gross, an assistant professor in the University of Cincinnati’s Department of Biological Sciences, and his colleagues compared the...

Scientists turn stem cells into a fish embryo, overcoming major biological challenge. Charlottesville, VA (PRWEB) April 04, 2014 Scientists at the University of Virginia School of Medicine have overcome one of the greatest challenges in biology and taken a major step toward being able to grow whole organs and tissues from stem cells. By manipulating the appropriate signaling, the UVA researchers have turned embryonic stem cells into a fish embryo, essentially controlling embryonic...

New research at Washington University School of Medicine in St. Louis and Vanderbilt University Medical Center in Nashville has implicated a poorly understood protein called PLAC8 in the spread of colon cancer. While elevated PLAC8 levels were known to be associated with colon cancer, the researchers now have shown that the protein plays an active role in shifting normal cells lining the colon into a state that encourages metastasis. The work appears April 1 in the Journal of Clinical...

regeneration of zebrafish fin
2014-03-30 06:37:34

Instituto Gulbenkian de Ciencia The reason why some animals can regenerate tissues after severe organ loss or amputation while others, such as humans, cannot renew some structures has always intrigued scientists. In a study now published in PLOS ONE, a research group from Instituto Gulbenkian de Ciência (IGC, Portugal) led by Joaquín Rodríguez León provided new clues to solve this central question by investigating regeneration in an adult vertebrate model: the zebrafish. It was known...

NEW YORK, Jan. 30, 2014 /PRNewswire-USNewswire/ -- Patients with advanced hepatocellular (or liver) cancer have high mortality rates, with existing drugs demonstrating only a small, but significant survival advantage. By combining a zebrafish model of liver cancer with data from human tumors, researchers from the Icahn School of Medicine at Mount Sinai hope to identify potential genes of interest that can be targeted for new treatments for hepatocellular carcinoma, the most common...

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...
