How do you perform a differential gene expression analysis?

How do you perform a differential gene expression analysis?

First, the count data needs to be normalized to account for differences in library sizes and RNA composition between samples. Then, we will use the normalized counts to make some plots for QC at the gene and sample level. Finally, the differential expression analysis is performed using your tool of interest.

What is transcript expression?

Transcript expression level, refers to how abundant a transcript is, i.e. if a certain mRNA (a transcript) exist in many or few copies (expression level). DE analysis is the analysis of Differentially Expressed genes.

What does cufflinks do in RNA-Seq?

Cufflinks assembles transcripts, estimates their abundances, and tests for differential expression and regulation in RNA-Seq samples. It accepts aligned RNA-Seq reads and assembles the alignments into a parsimonious set of transcripts.

What is differentially expressed proteins?

A protein was considered to be expressed differentially if there was >two-fold difference in the spectral count ratios between the two samples.

What is transcript analysis?

Transcript analysis is an important methodology to study asynchronous online educational discourse. The purpose of this study is to revisit reliability and validity issues associated with transcript analysis. The goal is to provide researchers with guidance in coding transcripts.

What is genomics and Epigenomics?

Genomics is the study of information that is encoded within the full DNA sequence complement of an organism. Epigenetics is the study of how DNA is organised and regulated in the cell to promote a stably heritable phenotype without alterations in the DNA sequence.

What is a pipeline in RNA-Seq?

The first protocol covers the standard pipeline on RNA-seq data that interrogates the transcriptome at the gene level, which is usually referred as differentially expressed gene (DEG) analysis. This pipeline starts from the raw sequence reads, and ends with a set of differentially expressed genes.
