Abstract: | Caenorhabditis elegans and one of its close relatives, Caenorhabditis briggsae, are animal models that are commonly used for comparative studies to understand the evolution of developmental mechanisms and gene function. Although the two species appear nearly identical morphologically, comparative genomic analyses have revealed interesting differences between the genomes. Whether such differ- ences contribute to changes in developmental mechanisms and signalling pathways is an active area of research. One of the most well studied phenotypes associated with C. elegans signalling pathways are those that affect the specification of vulval tissue. Within the system of vuval development, mutants that exhibit the Mul- tivulva (Muv) phenotype are important as they show inappropriate divisions of vulva cells, which model tumour formation. Comparing gene function in different species genetic backgrounds can lead to an understanding of how genetic differ- ences contribute to different responses in cancer development. Genetic screens, conducted in our laboratory, yielded several genes whose loss of function results in a Muv phenotype and identified a novel regulator of C. briggsae vulval devel- opment, Cbr-ivp-3. Using the nematode C. briggssae as experimental system, we have characterized the tumour suppressor gene, Cbr-ivp-3, which impacts cell sig- nalling and cell division. I have carried out molecular genetic analyses of ivp-3 in both C. briggsae and C. elegans and have begun to characterize the functional role of Cbr-ivp-3. The findings in this thesis suggest that Cbr-ivp-3 is functioning to negatively regulate EGF/Cbr-lin-3. |
