Malignant worms: what cancer research can learn from C. elegans

Cancer Investigation
R Mako Saito, Sander van den Heuvel

Abstract

Developmental processes in the nematode C. elegans are controlled by pathways of gene functions that are analogous to those used in mammals. Hence, genetic studies in C. elegans have helped build the frameworks for these regulatory pathways. Many homologs of human genes that are targets for mutation in cancer have been found to function at distinct steps within such genetic pathways. This way, studies in C. elegans have provided important clues about the functions of human oncogenes and tumor suppressors. Understanding how human cancer genes function and act in signaling cascades is of great importance. This information reveals what kind of molecular changes contribute to the process of cell transformation. Moreover, additional candidate oncogenes and tumor suppressors may be revealed by identifying the functional partners of genes with an established role in cancer. Furthermore, identifying a cascade of gene functions increases the number of potential targets for therapeutic intervention, as blocking either one of multiple genes may interfere with signal transduction through the pathway. Simultaneous approaches in a number of different model systems act synergistically in solving pathways of gene functions. By using multiple m...Continue Reading

Anthelmintics (ASM)

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
