  • Summarized Experiment object containing expression data used for DEA and gene and sample metadata
  • DEA object, containing results of the differential expression

2.1 Load Data from DEA

# List with differential expression results 
DEA <- readRDS(params$DEAFile)

#SE object coming from DEA, but not containing specific contrast results
SE_DEA <- readRDS(params$SEFile)

2.2 Add DEA results to SE

14305 genes in 21 samples have been testes for differential expression.

Imposing a threshold of 1 on the Log2FC and 0.01 on the FDR (as specified in parameters), 437 genes are selected: 143 up-regulated genes and 294 down-regulated genes.


3. RESULTS NAVIGATION: Interactive Table

An interactive table show the results for the top 500 DEGs (ranked according to FDR).

DEGsTable(SE_DEA, FdrTh=0.01, logFcTh=1, maxGenes=500, saveDEGs=TRUE, outDir=OutputFolder)

4. RESULTS VISUALIZATION

4.1 Volcano plot

The results of the differential expression analysis are visualized by Volcano plot. An interactive version is included in the html (only genes with FDR < threshold), while a static version is saved.

Heatmaps for DEGs, showing scaled vst values.

5. TOPGO for Gene Ontology Enrichment analysis

Gene ontology enrichment analysis is performed on the set of 437 genes using TopGO with Fisher statistics and weight01 algorithm.

For each specified domain of the ontology:

  • Enrichment analysis on all DEGs or splitted in down- and up-regulated

5.1 Selection of modulated genes and generation of gene vectors

I generate vectors for the gene universe, all modulated genes, up-regulated genes and down-regulated genes in the format required by TopGo.

GeneVectors <- topGOGeneVectors(SE_DEA, FdrTh=FdrTh, logFcTh=logFcTh)
## Gene vector contains levels: 0,1
## Gene vector contains levels: 0,1
## Gene vector contains levels: 0,1

Therefore:

  • universe genes: 14305 genes
  • modulated genes: 437 genes
  • down-regulated genes: 294 genes of interest
  • up-regulated genes: 143 genes of interest

Then I set parameters according to the gene ontology domains to be evaluated. By default, Biological Process and Molecular Function domains are interrogated.

BpEval <- ifelse(length(grep('BP', params$TopGO))!=0, TRUE, FALSE)
MfEval <- ifelse(length(grep('MF', params$TopGO))!=0, TRUE, FALSE)
CcEval <- ifelse(length(grep('CC', params$TopGO))!=0, TRUE, FALSE)
