Theses and Dissertations
Type 2 diabetes mellitus has been diagnosed in ~21 million people in the United States and is closely correlated with obesity, prompting the need for a detailed understanding of adipocyte metabolism in the development of diabetes. The intake of excess nutrients surpasses the energy requirements of the cell and leads to increased mitochondrial stress in the adipocyte. We have shown that this is associated with increased levels of the mitochondrial metabolite fumarate. Fumarate can react with cysteine thiol groups to form the chemical modification S-(2-succino)cysteine (2SC), also termed protein succination. Succination is significantly increased in the adipose tissue of type …
