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.

Using Zebrafish Screening Model To Regulate Heart

harminka — Sun, 05 Jul 2009 13:03:06 -0500

Using zebrafish, researchers at the University of Pittsburgh have identified and described an enzyme inhibitor that allows them to increase the number of cardiac progenitor cells and therefore influence the size of the developing heart. The findings are described in the advance online version of Nature Chemical Biology.

Using Zebrafish To Provide Model For Melanoma in Humans

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

Mutated gene in zebrafish sheds light on blindness in humans

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.

First complete developmental blueprint of vertebrate

Researchers at the European Molecular Biology Laboratory (EMBL) have generated a digital zebrafish embryo - the first complete developmental blueprint of a vertebrate. With a newly developed microscope scientists could for the first time track all cells for the first 24 hours in the life of a zebrafish.

Zebrafish may help solve ringing in vets' ears

harminka — Thu, 01 May 2008 02:09:29 -0500

Ernest Moore, an audiologist and cell biologist at Northwestern University, developed tinnitus -- a chronic ringing and whooshing sound in his ears -- twenty years ago after serving in the U.S. Army reserves medical corps. His hearing was damaged by the crack of too many M16 rifles and artillery explosions. He suspects his hearing also suffered from hunting opossum with rifles as a kid on his grandmother's farm in Tennessee.

Deadly genetic disease prevented before birth in zebrafish

By injecting a customized "genetic patch" into early stage fish embryos, researchers at Washington University School of Medicine in St. Louis were able to correct a genetic mutation so the embryos developed normally.

Screening strategy using zebrafish targets genes that protect against hearing loss

harminka — Sat, 01 Mar 2008 04:28:33 -0600

A small striped fish is helping scientists understand what makes people susceptible to a common form of hearing loss, although, in this case, it’s not the fish’s ears that are of interest.

Oregon researchers discover a mechanism leading to cleft palate

harminka — Tue, 12 Feb 2008 09:07:20 -0600

By creating a genetic mutation in zebrafish, University of Oregon scientists say they've discovered a previously unknown mechanism for cleft palate, a common birth defect in humans that has challenged medical professionals for centuries.

Transparent fish to make human biology clearer

Zebrafish are genetically similar to humans and are good models for human biology and disease. Now, researchers at Children's Hospital Boston have created a zebrafish that is transparent throughout its life.

Zebrafish study shows key enzyme in gut is peacemaker

harminka — Wed, 12 Dec 2007 11:19:59 -0600

University of Oregon scientists, using zebrafish to study the gastrointestinal tract, say that an enzyme long assumed to be involved in digestion instead is a detoxifying traffic cop, maintaining a friendly rapport between resident gut bacteria and cells.

Transparent zebrafish help researchers track breast cancer

What if doctors could peer through a patient’s skin and see a cancer tumor growing? They’d be able to study how tumor cells migrate: how they look, how they interact with the blood system to find nourishment to grow and spread through the body.
