| Outline of Final Research Achievements |
Early experiments suggested the cause of body weight loss and emaciation of GTRAP-/- to be a decrease in food intake. The level of serum MCH, AgRP or NPY, which increases appetite, was not significantly different from that of the wild type, while alpha-MSH, which inhibits appetite, was significantly increased. POMC and the receptor for alpha-MSH, MC4R, were not changed in the hypothalamus. Fasted wild type mice showed the increased activity of AMPK-alpha due to the decrease in MC4R activity in response to appetite increase. However, Fasted GTRAP-/- mice showed suppressed AMPK-alpha activity, suggesting fasting state did not lead to the decrease in MC4R activity and the increase in MSH-alpha is the primary change in GTRAP-/- mice.
