Insect Models to Study Human Lipid Metabolism Disorders

Disorders of lipid metabolism such as obesity have become some of the most significant diseases of the twenty-first century. Despite these metabolic diseases affecting more than a third of the population in highly industrialized nations, the mechanisms underlying disease development remain poorly understood. Insect models, such as Drosophila melanogaster, offer a means of systematically examining conserved lipid metabolism and its pathology. Over the past several decades, Drosophila melanogaster has been used to greatly expand on our knowledge of metabolic disease, often taking advantage of the extensive genetic tools available to researchers. Additionally, Drosophila melanogaster has served and will continue to serve as a powerful tool for validating the results of genome-wide approaches to the study of diseases. This chapter explores the advancements of insect models in the study of lipid metabolism disorders as well as highlight opportunities for future areas of research.
