Alteration in diet and knockdown of detoxification genes impacts the response of C. elegans to oxygen deprivation stress. I hypothesized that feeding worms a vitamin D3-supplementation diet would result in differential oxygen deprivation stress response. We used a combination of wet lab and transcriptomics approach to investigate the effect of a vitamin-D3 supplemented diet on the global gene expression changes and the anoxia response phenotype of C. elegans (Chapter 2). C. elegans genome consists of 143 detoxification genes (cyp and ugt). The presence of a significant number of genes in these detoxification families was a challenge with identifying and selecting specific cyp and ugt genes for detailed analysis. Our goal was to understand the evolution, phylogenetic, and expression of the detoxification enzymes CYPs and UGTs in C. elegans (Chapter 3). We undertook a phylogenetic and bioinformatics approach to analyze the C. elegans, detoxification family. Phylogenetic analysis provided insight into the association of the human and C. elegans xenobiotic/endobiotic detoxification system. Protein coding genes in C. elegans have been predicted to be human orthologs. The results of this work demonstrate the role of C. elegans in the identification and characterization of vitamin D3 induced alterations in gene expression profile and anoxia response phenotypes and the identification of human orthologs for the detoxification enzymes and provides insight into the gene expression pattern.
