Project description:The rat pineal gland is a highly dynamic tissue with many hundreds of genes changing more than two-fold in a 24-hr daily rhythm as measured by Affymetrix GeneChip analysis. We sought to more completely understand this dynamic transcriptome using RNA-Seq in order to capture information regarding alternative splicing, novel exons, unannotated mRNAs, non-coding RNAs, etc. We also wished to identify transcripts that were selectively expressed in the pineal glands relative to other tissues. Toward this end we performed RNA-Seq on three types of samples; 1) a pool of pineal glands sampled at mid-day (ZT7); 2) a pool of pineal glands sampled at mid-night (ZT19); and a pool of 15 different tissues collected from 3 animals at mid-day (ZT7). Animals were housed in a 14:10 light:dark lighting cycle. PolyA-selected RNA was fragmented and sequenced on an Illumina GAII machine, yielding paired-end 51-mer reads.

Project description:The rat pineal transcriptome is highly dynamic, with many hundreds of transcripts changing more than two-fold on a 24-hr basis, as revealed earlier using Affymetrix GeneChip analysis. The retina is evolutionally related to the pineal gland so these two tissues share many gene expression patterns. This study more completely characterizes the temporally dynamic transcriptomes of these tissues using RNA-Seq to capture information regarding alternative splicing, novel exons, unannotated mRNAs, non-coding RNAs, and coding transcripts not represented on the Affymetrix chips. We also identified transcripts that were selectively expressed in the pineal gland relative to other tissues by comparing pineal samples to a sample of pooled non-pineal tissues. The transcriptomes of the rat pineal gland and retina were sequenced using samples collected at 6 time points throughout a 24-hour cycle to identify rhythmically expressed transcripts. The transcriptomes of pools of mixed tissues collected at mid-day (ZT7) and mid-night (ZT19) were also sequenced for comparison to aid in determining pineal-enriched transcripts.

Project description: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. This study characterizes this temporally dynamic transcriptome using RNA-Seq to capture information regarding alternative splicing, novel exons, unannotated mRNAs, non-coding RNAs and coding transcripts not represented on the Affymetrix chips. The rat pineal transcriptome was sequenced in samples from four ages, from embryonic day 21 through adult. At each age, samples were taken at mid-day and mid-night. Data were collected to describe the changes in the developing pineal transcriptome and to identify transcripts that exhibit day/night differences in expression at each age.

Project description: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. We have analyzed the rat pineal transcriptome at mid-day and mid-night to identify genes that exhibit night/day changes in expression. We have also used these data to characterize the non-rhythmic features of the transcriptome that set the pineal gland apart from other tissues by comparing them to the median expression in other rat tissues as found in the Genomics Institute of the Novartis Research Foundation (GNF), Entrez Gene Expression Omnibus (GEO) dataset GDS589. Experiment Overall Design: Rat pineal glands were obtained at mid-day and mid-night for RNA extraction and hybridization to Affymetrix microarrays. Triplicates of pooled pineal glands were analyzed at each timepoint.
