The roundworm C. elegans may be the key in unlocking the biological mystery of why we sleep. Researchers at the University of Pennsylvania's School of Medicine report that the round worm has a sleep-like state, joining most of the animal kingdom in displaying this physiology. This research has implications for explaining the evolution and purpose of sleep and sleep-like states in animals. Additionally, genetic work associated with the study provides new prospects in identifying...

NEW YORK - Two Americans won the Nobel Prize in medicine Monday for discovering a way to silence specific genes, a revolutionary finding that scientists are scrambling to harness for fighting illnesses as diverse as cancer, heart disease and AIDS. Andrew Z. Fire, 47, of Stanford University, and Craig C. Mello, 45, of the University of Massachusetts Medical School in Worcester, will share the $1.4 million prize. They were honored remarkably swiftly for work they published together just eight...

Ten genes that may make patients more or less susceptible to a common anesthetic agent have been identified by researchers using tiny worms and sophisticated technology that eliminates the activity of individual genes. "We are anesthetizing 25 million patients a year in the United States alone; we put them to sleep and wake them up and we still don't know a lot about why it happens," said Dr. Steffen E. Meiler, vice chair of research for the Medical College of Georgia Department of...

University of Utah biologists found a gene that controls rhythmic events in a worm's life: swallowing food, laying eggs and pooping. If the gene is disabled, the worms can't swallow, so they die. If the gene is partly restored so the worms can swallow, they have trouble reproducing and get constipated. "We have found a gene that is important for the control of fundamental rhythms in nematode worms," says biology professor and physician Andres Villu Maricq, a member of the Brain Institute at...

Though the study of aging in the nematode model organism C. elegans has provided much insight into this complex process, it is not yet clear whether genes involved in aging in the worm have a similar role in mammals. In a recent study, Dr. Hekimi and colleagues of McGill University (Canada) report that inactivation of the gene mclk1, the murine ortholog of the C. elegans gene clk-1, results in increased cellular fitness and prolonged lifespan in mice. The gene clk-1 in the worm, as well as...

RIVERSIDE, Calif. "“ Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans. The researchers published their findings in the Aug. 18 issue of the journal Nature in a paper titled, Animal virus replication and RNAi-mediated antiviral silencing in C. elegans. UCR Professor of Plant Pathology Shou-Wei Ding co-authored the paper with...

How does a multi-cellular organism with specialized organs and tissues develop from a single cell? A team of genomics researchers has moved closer to answering this question by creating the first comprehensive diagram of the molecular interactions that orchestrate early embryo development. The work--a collaborative effort by scientists from New York University (NYU), Harvard University, the Max Planck Institute and Cenix BioScience in Dresden, Germany--appears in the Aug. 11 issue of the...

WASHINGTON (Reuters) - How well you respond to stress predicts how long you will live, at least if you are a little worm, U.S. scientists reported on Monday. Genetically identical worms responded to stress in greatly different ways -- and those with more active stress reactions lived much longer than worms with less active stress proteins, the researchers found. More active stress responses suggest the animal is coping with the stress. The findings will almost certainly apply to humans in...

Caenorhabditis elegans

Caenorhabditis elegans is a species of parasitic roundworm in the Nematoda phylum. It can be found in temperate regions, in many different areas of the world. It prefers to reside in nutrient rich soils. Its scientific name is derived from the Greek terms Caeno, meaning recent, rhabditis, meaning rod-like, and the Latin term elegans, which means elegant. It was first named by Maupas in 1900, but was not classified in the Caenorhabditis subgenus until 1952 by Osche. Caenorhabditis elegans...
