ANIMAL MODELS AND METHODS FOR ANALYSIS OF LIPID METABOLISM AND SCREENING OF PHARMACEUTICAL AND PESTICIDAL AGENTS THAT MODULATE LIPID METABOLISM

摘要

Drosophila melanogaster and C. elegans that have been genetically modified to express or mis-express proteins involved in the sterol regulatory element binding protein (SREBP) pathway are described. These genetically modified animal models have identifiable phenotypes that make them useful in assays for studying lipid metabolism, other genes implicated in lipid metabolism, and compounds capable of modulating lipid metabolism pathways. Methods for studying lipid metabolism in living mematodes using fluorescently labeled fatty acid conjugates, such BODIPY fatty acid conjugates, are also described. Novel SREBP pathway nucleic acid and protein sequences are also described.
