| Outline of Final Research Achievements |
Our focus is on molecular mechanism of overeating regulated by endoplasmic reticulum (ER) stress in this research. In the first year we have performed elaborate analysis of overeating itself and preliminary analysis of function of hormones and neurons when overeating is induced. In the second year we have performed screening of responsive genes for overeating and functional analysis of the genes. These analyses revealed that ER stress inducible overeating is not caused by abnormal regulation of leptin and ghrelin, and that specific neurons and genes are responsible for ER stress inducible overeating. We also found interaction between an ER stress responsive molecule and a receptor of regulatory hormone in food intake.
