Project description:Transcription profiling of sense and antisense transcripts of 10 tissues each from human, mouse, and rat. This SuperSeries is composed of the following subset Series: GSE41462: Antisense exon profiling across human, mouse, and rat GSE41464: Sense exon profiling across human, mouse, and rat We profiled the sense and antisense transcription level of 10 tissues each from human, mouse, and rat. Only Affymetrix core probesets were used. Two technical replicates per sample. Reference for protocol: Ge, X., Rubinstein, W.S., Jung, Y.C., and Wu, Q. (2008).

Project description:Increasing numbers of sense–antisense transcripts (SATs), which are transcribed from the same chromosomal location but in opposite directions, have been identified in various eukaryotic species, but the biological meanings of most SATs remain unclear. To improve understanding of natural sense–antisense transcription, we performed comparative expression profiling of SATs conserved among humans and mice. Using custom oligo-arrays loaded with probes that represented SATs with both protein-coding and non-protein–coding transcripts, we showed that 33% of the 291 conserved SATs displayed identical expression patterns in the two species. Among these SATs, expressional balance inversion of sense–antisense genes was mostly observed in testis at a tissue-specific manner. Northern analyses of the individual conserved SAT loci revealed that: (1) a smeary hybridization pattern was present in mice, but not in humans, and (2) small RNAs (about 60 to 80 nt) were detected from the exon-overlapping regions of SAT loci. In addition, further analyses showed marked alteration of sense–antisense expression balance throughout spermatogenesis in testis. These results suggest that conserved SAT loci are rich in potential regulatory roles that will help us understand this new class of transcripts underlying the mammalian genome.

Keywords: Expression profile of mouse and human sense-antisense transcript The RNA samples used for the mouse oligo-array experiments came from the brain, NIH3T3 cells (fibroblast cell line), liver, heart, and testis. RNA from mouse tissue (C57BL/6J, 8 to 10 weeks, male and female mixed) and mouse fibroblast line NIH3T3 was isolated by using Trizol reagent (Invitrogen). The mouse custom oligo DNA microarray chip (microarray format: 11K) contained 3896 probes that represented genes in 1948 exon-overlapping SAT (sense-antisense transcript) pairs.The same total RNA samples were reciprocally labeled with Cy3 or Cy5, hybridized to the oligo DNA on the chip, and dye-normalized. The data on all genes on the chip were used to enable the Feature Extraction software to produce the processed signals. The total mean signal on the mouse chip in each hybridization experiment was adjusted with to a value of 4872.3. The RNA samples used for human microarray experiments came from brain, HF19 cells (fibroblast cell line), heart, liver and testis. The total brain, heart, and testis RNA used in the array experiments was purchased from Ambion. Total RNA was isolated from the fibroblast cells by using Trizol reagent (Invitrogen). The same total RNA samples were labeled with single color Cy3, hybridized to the oligo DNA on the chip, and dye-normalized; the processed signals were obtained by using Feature Extraction software (Agilent Technologies). The custom oligo DNA microarray chip (microarray format: 11K) contained 2793 probes for 1486 pairs of exon-overlapping SATs. The data on all genes on the chip were used to enable the Feature Extraction software to produce the processed signals. For further analysis, the Cy3-labeled processed signal was used as the processed signal from the expression of a particular gene. The total mean signal on the human chip in each hybridization experiment was adjusted to 1491.6, so that the relative differences in gene expression could be compared among cell lines and tissues.
