Abstract

Intermediary metabolites of fatty acid biosynthesis are used by the central nervous system to signal changes in body weight in response to alterations in dietary nutrients. This nutrient-sensing mechanism links cellular bioenergetics to complex animal behavior. The central molecule in this pathway, malonyl-coenzyme A (CoA), is the product of the rate-limiting and highly regulated step in fatty acid biosynthesis. Increased concentrations of hypothalamic malonyl-CoA, mediated by nutrient or endocrine cues, inhibit food intake and enhance peripheral energy expenditure resulting in a reduction in body weight. Conversely, the depletion of malonyl-CoA leads to an obese phenotype. Here, we describe the regulation and mechanism by which malonyl-CoA regulates body weight.
