Linking Human Disease Genes with C. elegans Genes

Human Disease Genes and C. elegans Genes

Although the phenotypes of the human diseases and the mutant defects in C. elegans seem about as unrelated as possible, the cellular and molecular details of many of these defects are highly related. Using C. elegans as a model organism, much can be learned at the cellular and molecular level about a specific biological process, by understanding the mode of action of the orthologous genes involved.

The recent findings suggest the absence of the mammalian organ(s) affected by a disease does not preclude the use of nematodes to shed light on complex disease mechanisms and find novel target genes for treatments. For example, the ksr gene, discovered in C. elegans has recently been proposed as a druggable target to overcome Ras-driven cancers (1).

Significance

aThis is a fine example of how modifier mutations can be validated using different model organisms in which a given disease gene is being modeled.

bThe genetic pathways were practically identical: the tyrosine kinase growth factor receptor-Ras-Raf-MEK-MAPK pathway. the same set of orthologs is required for these three biological processes: vulval induction in C. elegans, eye development in D. melanogaster, and cell proliferation in mammalian cell culture.

cIdentification of the ksr gene in D. melanogaster and C. elegans in the mid-1990s. The discovery of this gene has great medical implications for cancer.

dCancer and the Him phenotype are both the result of chromosome segregation defects.
