Using Nematode worms
, scientists found even those given enhanced antioxidant powers to deal with tissue damaging "free radicals" did not live longer.
In the nematode worm
, stress signals detected by sensory neurons participate in the heat-shock response and over-excitation of this pathway can lead to misfolded protein in muscles (Morimoto).
In some dirty water (left over from the recent floods, Biffel noted), the children discovered various debris and an occasional slow-moving nematode worm
elegans, a millimeter-long nematode worm
whose simple body and small number of genes make it a useful tool for biologists.
The researchers studied the genomes of 12 species of Drosophila or fruit fly, four species of nematode worm
, and 10 species of primate, including humans.
The nematode worm
Anisakis simplex can cause serious health problems, especially in pregnant women and elderly people.
Their work, which hinged around studies of a tiny nematode worm
, identified key genes regulating organ development and the programmed death of cells.
The work on the nematode worm
is described as a breakthrough on a par with the cloning of Dolly the sheep.
On board the Space Shuttle Columbia mission STS-107, researchers were studying the growth and reproductive behavior of the nematode worm
Caenorhabditis elegans, but the mission ended in tragedy in 2003 when the shuttle broke up during reentry.
Sirtuins had previously been linked to ageing and longevity in yeast, the nematode worm
and the fruit fly, organisms commonly used as models for the biology of human ageing.
Cancer hope: The soil-dwelling nematode worm
Caenorhabditis elegans could hold the key to new treatments for cancer, researchers say.
The creature is a soil-dwelling nematode worm
, less than one millimetre long.
