How is gastrulation initiated in C. elegans?

C. elegans gastrulation occurs at an early stage, beginning when the embryo is composed of just 26 cells, suggesting some promise for connecting the rich array of developmental mechanisms that establish polarity and pattern in embryos to the force-producing mechanisms that change cell shapes and move cells interiorly.

What major discoveries were made in C. elegans?

Seminal discoveries about programmed cell death were made using C. elegans as a model system and earned Brenner, Sulston and Robert Horvitz the Nobel Prize in Physiology or Medicine in 2002. Another major discovery made using C. elegans was that of RNA interference, gene silencing by double-stranded RNA.

What is special about the nematode C. elegans?

elegans, which has since been extensively used as a model organism. It was the first multicellular organism to have its whole genome sequenced, and as of 2019, is the only organism to have its connectome (neuronal “wiring diagram”) completed.

What research is C. elegans used for?

C. elegans has been used as a model organism to study human diseases ranging from Parkinson’s disease to mitochondrial diseases, as well as studying the immune system.

Why are C. elegans used in research?

C. elegans grown in large numbers, can be easily screened for effects of novel drugs on complex processes involved in human disease. C. elegans is particularly useful the study of ageing processes because the organism passes through several distinct phases of life which can be observed physiologically and genetically.

Why is Caenorhabditis elegans C. elegans considered a good model organism in research?

C. elegans is a nematode worm and is significantly anatomically simpler than a human, however, it does share many similarities at the molecular level making it a good candidate for a model organism.

Why is C. elegans an important model for genetic studies relevant to human biology and disease?

Because of evolutionary conservation of gene function and experimental tractability, C. elegans represents an ideal “model organism” to study basic genetic and molecular mechanisms of human development and disease.

What is the importance of C. elegans?

Caenorhabditis elegans is now the model organism of choice for a growing number of researchers. A combination of its apparent simplicity, exquisite genetics, the existence of a full molecular toolkit and a complete genome sequence makes it ideal for rapid and effective study of gene function.

Why is it important to study C. elegans?

C. elegans is particularly useful the study of ageing processes because the organism passes through several distinct phases of life which can be observed physiologically and genetically.
