leukemiasGO
is microarray gene expression data from the studies of
Kohlmann et al. (2008) and Haferlach et al. (2010). Processed as described
in Risueno et al. (2010). Adapted from package leukemiasEset
(see
leukemiasEset). Differential gene expression was
performed using the DESeq2
package comparing the
sample classes NoL (no leukemia) against AML, ALL, and CML.
GO annotation was done with the annotate
and hu6800.db
packages from Bioconductor. The topGO
package was utilized to perform
a GO enrichment test based on Fisher's exact test using the 'elimScore'
method.

A data.frame
that contains the gene ontology enrichment and differential
gene expression tests data.
Description of the columns:
GO
- character vector with GO ids of the GO terms
Term
- character vector with GO terms
Annotated
- integer vector with number of GO annotated genes per term
Significant
- integer vector with number of significant differential expressed genes per term
Expected
- numeric vector with expected number of differential expressed genes per term
pvalCutOff
- numeric vector with p values from the GO enrichment test
padj
- numeric vector with adjusted p values (FDR) from the GO enrichment test
LogEnrich
- numeric vector with the logarithm of the GO term enrichment (significant/expected)
PROBEID/ENSEMBL
- list of names of genes differentially expressed per GO term
log2fc/log2FoldChange
- list of logarithm of fold changes of all genes per GO term
p/pvalue
- list of p values of all differential gene expression
