Title: Thyroid Hormone and Insulin Metabolic Actions on Energy and Glucose Homeostasis
Description: Faced with an environment of constantly changing nutrient availability, mammals have adapted complex homeostatic mechanisms to maintain energy balance. Deviations from this balance are largely corrected through a concerted, multi-organ effort that integrates hormonal signals with transcriptional regulatory networks. When these relationships are altered, as with over-nutrition and insulin resistance, metabolic disease ensues. Here, I present data concerning two distinct transcriptional pathways--one for thyroid hormone (TH) and one for insulin--that confer hormone responsiveness on metabolic gene programs that preserve energy homeostasis.
