(Submitter supplied) The zebrafish pineal gland (epiphysis) is an autonomous clock organ. In addition to being a site of melatonin production, it contains photoreceptor cells and functions as a circadian clock pace maker, making zebrafish a useful model system to study the developmental control of expression of genes associated with melatonin synthesis and photodetection, and the circadian clock. Here we have used DNA microarray technology to study the zebrafish pineal transcriptome. more...

(Submitter supplied) Chick pinealocytes exhibit all the characteristics of a complete circadian system, comprising photoreceptive inputs, molecular clockworks and an easily measured rhythmic output, melatonin biosynthesis. We used microarray analysis to investigate the expression of approximately 8000 genes within cultured pinealocytes subjected to both LD and DD cycles. We report that a reduced subset of genes were rhythmically expressed in vitro compared to those previously published in vivo, and that gene expression rhythms were lower in amplitude, although the functional distribution of the rhythmic transcriptome was largely similar. more...

(Submitter supplied) Biological processes are optimized by circadian and circannual biological timing systems. In vertebrates, the pineal gland plays an essential role in these systems by converting time into a hormonal signal, melatonin; in all vertebrates, circulating melatonin is elevated at night, independent of lifestyle. At night, sympathetic input to the pineal gland, originating from the circadian clock in the suprachiasmatic nucleus, releases norepinephrine. more...

(Submitter supplied) We describe a method for isolating RNA suitable for high-throughput RNA sequencing (RNA-seq) from small numbers of fluorescently labeled cells isolated from live zebrafish (Danio rerio) embryos without using costly, commercially available columns. This method ensures high cell viability after dissociation and suspension of cells and gives a very high yield of intact RNA. We demonstrate the utility of our new protocol by isolating RNA from fluorescence activated cell sorted (FAC sorted) pineal complex neurons in wild-type and tbx2b knockdown embryos at 24 hours post fertilization. more...

(Submitter supplied) The cone-rod homeobox gene (Crx) encodes Crx, a transcription factor selectively expressed in two cell types, retinal photoreceptors and the melatonin secreting pinealocytes of the pineal gland. In this report the role of Crx in regulating gene expression in the mammalian pineal gland was extended using Affymetrix GeneChip technology. Deletion of Crx results in broad modulation of the mouse pineal transcriptome, including a >2-fold downregulation of 543 genes and a >2-fold upregulation of 745 genes. more...

(Submitter supplied) Pineal function follows a 24-hour schedule, dedicated to the conversion of night and day into a hormonal signal, melatonin. In mammals, 24-hour changes in pineal activity are controlled by a neural pathway that includes the central circadian oscillator in the suprachiasmatic nucleus and the superior cervical ganglia (SCG), which innervate the pineal gland. In this study, we have generated the first next-generation RNA sequencing evidence of neural control of the daily changes in the pineal transcriptome. more...
