Abstract: Objective The aims of this study were to determine whether striatal neuropeptides(dynorphin(DYN), enkephalin 1(ENK1), substance P(SP), cholecystokinin(CCK)) and dopamine receptor 1 and 2(D1r and D2r) are regulated by the molecular clock; whether their rhythmic changes depend on the matural molecular clock. Methods Twenty-four hour mRNA oscillations of these genes were evaluated in the mouse striatum at early postnatal(postnatal day 3), pre-weaning(postnatal day 14), and adult(postnatal day 60) stages. At P3, no daily oscillations were observed. Results A significant time effect was present for D2r, DYN, and ENK1 at P14, and for all genes except D1r, at P60. Conclusion Circadian expression of these neurotransmitter-related genes develops in the mouse striatum gradually.
