| Research Abstract |
Intracerebroventricular (icv) injection of novel peptide, NU1 and NU2, increased the food intake and body temperature in a dose-dependent manner in rats. When expression of mRNA levels in the hypothalamus and midbrain/brainstem after icv injection of these peptides were examined using gene tip analysis, prostaglandin E synthetase mRNA and cyclooxygenase mRNA expressions increased dramatically. On the other hand, pretreatment with indomethacin completely blocked the increase of body temperature induced by NU1 and NU2. These results suggest that NU1 and NU2 increase the body temperature through prostaglandin E.
