An end to end workflow for differential gene expression using
ثبت نشده
چکیده
In this article, we walk through an end–to–end Affymetrix microarray differential expression workflow using Bioconductor packages. This workflow is directly applicable to current “Gene” type arrays, e.g. the HuGene or MoGene arrays but can easily adapted to similar platforms. The data re–analyzed is a typical clinical microarray data set that compares inflammed and non–inflammed colon tissue in two disease subtypes. We will start from the raw data CEL files, show how to import them into a Bioconductor ExpressionSet, perform quality control and normalization and finally differential gene expression (DE) analysis, followed by some enrichment analysis. As experimental designs can be complex, a self contained introduction to linear models is also part of the workflow. This article is included in the Bioconductor gateway.

متن کاملBioC2014: RNA-Seq workflow for differential gene expression
This lab will walk you through an end-to-end RNA-Seq differential expression workflow. We will start from the FASTQ files, align to the reference genome, prepare gene expression values as a count table by counting the sequenced fragments, perform differential gene expression analysis, and visually explore the results. This lab covers the basic introduction. For a more in-depth explanation of th...

متن کاملRNA-Seq workflow: gene-level exploratory analysis and differential expression
Here we walk through an end-to-end gene-level RNA-Seq differential expression workflow using Bioconductor packages. We will start from the FASTQ files, show how these were aligned to the reference genome, and prepare a count matrix which tallies the number of RNA-seq reads/fragments within each gene for each sample. We will perform exploratory data analysis (EDA) for quality assessment and to e...
متن کاملRegulatory effects of cis- and trans-LncRNAs on differential expression of genes following infection with viral hemorrhagic septicemia virus in rainbow trout (Oncorhynchus mykiss)
In this study the cis and trans regulatory effect of long non-coding genes (lncRNA) on the expression of genes in fish infected by Viral hemorrhagic septicemia virus (VHS) was investigated using RNA-seq technology. At the end of experimental period (the thirty fifth day), total RNA was extracted from spleen tissue (group treated with virus) and physiological serum (control group) was used to pr...
