Massive-Scale RNA-Seq Analysis of Non Ribosomal Transcriptome in Human Trisomy 21. Hybridization- and tag-based technologies have been successfully used in Down syndrome to identify genes involved in various aspects of the pathogenesis.
However, these technologies suffer from several limits and drawbacks and, to date, information about rare, even though relevant, RNA species such as long and small non-coding RNAs, is completely missing. Indeed, none of published works has still described the whole transcriptional landscape of Down syndrome. Although the recent advances in high-throughput RNA sequencing have revealed the complexity of transcriptomes, most of them rely on polyA enrichment protocols, able to detect only a small fraction of total RNA content. On the opposite end, massive-scale RNA sequencing on rRNA-depleted samples allows the survey of the complete set of coding and non-coding RNA species, now emerging as novel contributors to pathogenic mechanisms.

Galaxy provides the tools necessary to creating and executing a complete RNA-seq analysis pipeline. This exercise introduces these tools and guides you through a simple pipeline using some example datasets. Familiarity with Galaxy and the general concepts of RNA-seq analysis are useful for understanding this exercise. This exercise should take 1-2 hours. You can check your work by looking at the history and visualization at the bottom of this page, which contain the datasets for the completed exercise. Input Datasets Below are small samples of datasets from the Illumina BodyMap 2.0 project; specifically, the datasets are paired-end 50bp reads from adrenal and brain tissues.

Figure 2 : Defining an epigenetic code : Nature Cell Biology. Taxonomy browser (Bos taurus) Txid9913[Organism:noexp] - Nucleotide result. Bos taurus assembly. The genome of the domestic cow, Bos taurus, was sequenced using a mixture of hierarchical and whole-genome shotgun sequencing methods.
The sequences were assembled by the Center for Bioinformatics and Computational Biology at University of Maryland (CBCB) using the Celera Assembler . Two major releases have been made available to the public: UMD2 (April 2009)  and UMD3.0 (August 2009) . A minor release UMD3.1 has been made available to the public in December 2009. The UMD3.1 assembly is identical in almost all respects to UMD3.0. The only changes are in the AGP file deposited at GenBank. The first release, UMD2, published in Genome Biology in April 2009 , assembled 35.62 million reads into a 2.85 billion bp genome out of which 2.61 billion (91%) bp were placed on chromosomes. RNA Seq - GQ Wiki. From GQ Wiki Use RNA-Seq Workflow to measure gene expression profiles using NGS sequencing. This analysis is sometimes also referred to as Digital Gene Expression.
Example use cases You have 40 million Illumina reads derived from healthy human liver and human hepatoma samples. You would like to see overexpressed genes in sample. RNA-Seq takes as input one or two experiments, processes them against the Transcriptome and the Genome of a given species, and produces various data: a report with statistics, two spreadsheets, a databases of annotated genes by read counts. Video for Demonstration There are three steps in using this workflow: Get Data to the Server Ensure that your sequence data fies are on the GenomeQuest server.
