(Submitter supplied) Homeobox genes generally encode transcription factors involved in regulating developmental processes. In the pineal gland, a brain structure devoted to nocturnal melatonin synthesis, a number of homeobox genes are also expressed postnatally; among these are the LIM homeobox 4 gene (Lhx4) and the brain‐specific homeobox gene (Bsx). As part of a larger study, we used of siRNA technology to knock down Lhx4 or Bsx expression in cultured adult rat pinealocytes. more...

(Submitter supplied) The vertebrate pineal gland is dedicated to the production of the hormone melatonin, which increases at night to influence circadian and seasonal rhythms. This increase is associated with dramatic changes in the pineal transcriptome. Here, single-cell analysis of the rat pineal transcriptome was approached by sequencing mRNA from ~17,000 individual pineal cells, with the goals of profiling the cells that comprise the pineal gland and examining the proposal that there are two distinct populations of pinealocytes differentiated by the expression of Asmt, which encodes the enzyme that converts N-acetylserotonin to melatonin. more...

(Submitter supplied) The transcriptome of the rat pineal gland is highly dynamic, with many hundreds of genes changing more than two-fold on a 24-hr daily rhythm, as revealed earlier using Affymetrix GeneChip analysis. Several key transcription factors and enzymes are known to change dramatically during development of the pineal gland. Studies on a small number of genes indicate that the onset of rhythmic expression generally occurs later in development. 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...

Methods: Total RNA from retina and pineaal glands of Rhesus Macauqes euthanized at 4 timepoints (Dawn, Day, Dusk and Night) was deep sequenced, in triplicate, using Illumina HiSeq2000. Reads were aligned using STAR aligner and differential expression was asssessed using DESeq2. more...

(Submitter supplied) Disruption of the physiologic sleep-wake cycle and low melatonin levels frequently accompany cardiac disease, yet the underlying mechanism has remained enigmatic. Immunostaining of sympathetic axons in optically cleared pineal glands from humans and mice with cardiac disease revealed their substantial denervation compared to controls. Spatial, single-cell, nuclear, and bulk RNA sequencing traced this defect back to the superior cervical ganglia (SCG), which responded to cardiac disease with accumulation of inflammatory macrophages, fibrosis, and the selective loss of pineal gland-innervating neurons. more...
