Outline of Final Research Achievements |
In multi-organ creatures, including human beings, inter-organ metabolic communication is essential to regulate systemic metabolism. We examined how the inter-organ communication functions in response to alterations in external environment. Thereafter, we elucidated that 1) increased amino acid intake induces hypertriglyceridemia via a neuronal relay system, 2) hypoxic responses in steatotic liver are involved in gallstone formation, and 3) fatty acids promote glucose-stimulated insulin secretion via a newly-identified receptor family. Thus, a variety of inter-organ systems for metabolic homeostasis are ironically involved in obesity-related disorders.
