Ceramide Biosynthesis and NEET Proteins Impact Development, Function, and Maintenance of the Caenorhabditis elegans Germline

Description: I used the C. elegans genetic model to examine the role of ceramide biosynthesis (sphingolipid pathway) and iron regulation and found that each process impacts germline development and function. Using a sphingolipid specific antibody mAb15B4, I found that sphingolipids are associated with germ granules (P granules) within C. elegans and zebrafish; thus, suggesting conservation of macromolecules associated with germ granules. Phenotype analysis of ceramide biosynthesis mutants in C. elegans reve… more

The Metabolic Physiology of Planarian Flatworms

Description: Using a high throughput closed respirometry method to measure oxygen consumption, I determined metabolic rates in asexual and sexual Schmidtea mediterranea and Girardia dorotocephala, as a function of temperature, taxon, stressors, reproductive mode, age, regeneration, and specific dynamic action. This study has shown that oxygen consumption can reliably be measured in planaria using optode closed respirometry, and also provided a reliable method for measuring wet mass in planaria, which has be… more

Phenotype Analysis of the CISD Gene Family Relative to Mitochondrial Function in Caenorhabditis elegans

Description: NEET proteins belong to a unique class of [2Fe-2S] cluster proteins that have been shown to participate in various biological processes such as regulating iron, reactive oxygen species and apoptosis within the cell and are localized to the mitochondria. Disruption of the mitochondrial NEET proteins are associated with different human diseases such as obesity, neurodegeneration, cancer and diabetes. In humans, a missense mutation in the CISD2 gene results in a heritable multisystem disorder term… more
