As I spoke about before, C. elegans is a useful model for different neuronal developmental disorders. Previously, I showed how the worm usually moves. In this video [found here], you can see an Unc mutation. Unc are a whole class of genes that affect neurons and muscle movement that have some human homologs. For instance, Unc-39 seems to be a homolog to the human gene Six5, which is related to myotonic dystrophy (for more information, see here). As we learn more about these genes in worms, we can study which types of drugs or other agents might help these neurons to develop or function normally and relieve the symptoms of the mutation, allowing the worm to move typically (or like wild-type, the unmutated worm). This can then lead to the development of treatments for the homologous human disorders.
