| Outline of Final Research Achievements |
The regulatory mechanism of the expression of neuromedin U (NMU) in the rat pars tuberalis. Quantitative PCR showed that melatonin receptor MT1a and adenosine receptor A2b are highly expressed in the rat pars tuberalis. In rat brain slice culture experiment, NMU mRNA expression was significantly suppressed by melatonin and significantly increased by adenosine. It is suggested that diurnal rhythm expression of NMU in the rat pars tuberalis is antagonistically regulated by adenosine and melatonin.
