How the microscopic C. elegans worm won 4 Nobel Prizes

Four Nobels

The 1-millimeter nematode has helped scientists recognize however steadfast cells are instructed to termination themselves and however the process goes awry successful AIDS, strokes and degenerative diseases. (That enactment was the taxable of the 2002 Nobel Prize successful physiology oregon medicine.) Self-proclaimed “worm people” were recognised by the Nobel committee successful 2006 for discovering cistron silencing, which became the ground for an wholly caller people of drugs. Two years later, the chemistry prize went to scientists who utilized nematodes to assistance invent cellular “lanterns” that allowed biologists to spot the interior workings of a cell.

For each prize, a laureate made definite to convey the worm for its contributions, though possibly the astir celebrated motion came from Sydney Brenner, who won the archetypal “worm Nobel.” “Without doubt, the 4th victor of the Nobel Prize this twelvemonth is Caenorhabditis elegans,” helium said successful his lecture successful Stockholm.

‘Experimental dream’

One of the C elegans’ virtues is its simplicity, which allows scientists to trial hypotheses astir cardinal biologic concepts successful a exemplary that is casual to understand. The nematodes person conscionable 959 cells — a remarkably manageable number, compared with our trillions of cells — each of which scientists person named and charted from fertilisation to death. The destiny of each compartment is casual to map, since the worms go translucent nether the airy of a microscope and rhythm done each developmental stages successful astir 3 days.

The nematode was the archetypal carnal to person its genome wholly deciphered — successful 1998, years earlier scientists were capable to bash the aforesaid for flies and mice. The worm is inexpensive, casual to store and wholly self-sufficient erstwhile it comes to reproduction; pistillate C. elegans person functional sperm that let them to inseminate themselves.

“It’s an experimental dream,” said Judith Kimble, a nematode researcher astatine the University of Wisconsin, Madison.

Bonding implicit worms

Kimble attributes overmuch of the probe occurrence to the information that worm-bonded scientists thin to stock their resources and cooperate. Ruvkun, of the Harvard Medical School, and his co-winner, Victor Ambros, a prof of molecular medicine astatine UMass Chan Medical School, shared their findings with each other, allowing them to portion unneurotic the mechanics of microRNA.

The C. elegans probe assemblage comes unneurotic each different twelvemonth astatine the International Worm Convention.
