Scientists Create Mammalian Cells With Single Chromosome Set
2011-09-08 06:14:18

  Researchers have created mammalian cells containing a single set of chromosomes for the first time in research funded by the Wellcome Trust and EMBO. The technique should allow scientists to better establish the relationships between genes and their function. Mammal cells usually contain two sets of chromosomes — one set inherited from the mother, one from the father. The genetic information contained in these chromosome sets helps determine how our bodies develop. Changes...

Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is? Does a normal circadian clock persist during evolution under constant darkness? A new study directly tackles these fundamental questions by investigating a species of cavefish, Phreatichthys andruzzii, which has lived isolated for 2 million years beneath the Somalian desert. Many fish species have evolved in the absence of sunlight in cave systems around...

Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible, however both birds and fish are able to re-grow the damaged hair cells and restore hearing. New research published in BioMed Central's open access journal BMC Neuroscience shows that growth hormone is involved in this regeneration in zebrafish. Researchers from Western Kentucky University and the University...

Researchers at the University of Bath have combined genetic data with mathematical modelling to provide insights into cells and how they differentiate. The findings, to be published in open-access journal PLoS Genetics on September 1st, demonstrate the utility of a systems biology approach and could have implications for understanding and treating diseases, including cancers, caused when cells start to function incorrectly. All cells derive from multipotent precursor cells (stem cells)....

Humans and zebrafish share mechanisms that regulate our circadian system, says TAU researcher Circadian rhythms "” the natural cycle that dictates our biological processes over a 24-hour day "” does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with weight control, jet lag and more. Now Prof. Yoav Gothilf of Tel Aviv University's Department of Neurobiology at the George S. Wise Faculty of Life Sciences is looking to...

(Ivanhoe Newswire) -- Scientists have found a new way to detect zinc in zebrafish. They say this discovery could help them better understand diseases like type 2 diabetes, prostate cancer and Alzheimer's disease. Zinc is found throughout the body and is involved in metabolic pathways that affect the function of the immune system and brain, reproduction, and sexual development. It is also known to be a key element in treating a range of diseases. Researchers are unclear whether zinc causes...

AGAWAM, Mass. July 6, 2011 /PRNewswire/ -- Microtest Laboratories has announced a new fast-track test to screen plastics and polymers in medical devices for toxicity using Zebrafish embryos (Danio rerio), a technique already widely utilized in drug development studies. "Testing has revealed that Zebrafish embryos are highly susceptible to toxins. In fact, Zebrafish labs are ubiquitous in most universities and research hospitals," said Steven Richter, Ph.D., president and scientific...

Fluorescent fish could hold the key to understanding diabetes and other diseases Scientists from Queen Mary, University of London have discovered a new way of detecting zinc in zebra fish, that could pave the way for furthering our understanding of diseases like type 2 diabetes, prostate cancer and Alzheimer's. The results will be announced today (3 July) at the Sixth International Symposium on Macrocyclic and Supramolecular Chemistry, in Brighton. Zinc is found throughout the body and...

IRVINE, Calif., June 28, 2011 /PRNewswire/ -- GeneTex, a leading manufacturer of high quality antibodies, is pleased to announce that they will be launching a full line of zebrafish antibodies. Zebrafish have been increasingly utilized as a model organism for scientific research. Due to their short lifecycles and relatively large clutch sizes, they are a useful model for genetic studies. Zebrafish eggs are externally fertilized; therefore, researchers can control and manipulate the...

Failure in nerve-fiber navigation corrected in zebrafish model; suggests possibility of a drug treatment BOSTON, June 6, 2011 /PRNewswire-USNewswire/ -- Spinal muscular atrophy (SMA) is the leading genetic cause of death in children under 2, with no treatment other than supportive care. In the Proceedings of the National Academy of Sciences (Early Edition, week of June 6), researchers at Children's Hospital Boston show how loss or mutation of the SMA gene causes progressive muscle...

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...
