Diurnal Variation of Melatonin Receptors in Danio rerio (Zebrafish)


ABSTRACT: To gain a better understanding of the diurnal variation in gene expression, we analyzed the changes in gene expression in the eye of zebrafish. Dual color oligonucleotide microarrays were used to compare total RNA harvested from eyes of adult zebrafish at midday and midnight. Statistical analyses identified 44 genes which showed significant, 2-fold or more change; 26 genes showed decreased expression at midnight (D/L ≤ 0.5) and 18 genes showed increased expression at midnight (D/L ≥ 2). Seven genes were further analyzed using qPCR. The results of qPCR identified AANAT, Mel1a1, Mel1a3, Mel1b1, Mel1b2 and Melc as genes that showed significant change in expression at dawn, dusk, midday and midnight. These results suggest that expression of melatonin receptors is subject to diurnal regulation.
