Regulation of IL 20 Expression by Estradiol through KMT2B Mediated Epigenetic Modification

PLoS One
PMCID: 5091760
PMID: 27806114
DOI: 10.1371/journal.pone.0166090
call_split See protocol

[…] The microarray raw data deposited in ArrayExpress (accession E-MTAB-4923) was preprocessed with the justRMA function of the affy Bioconductor package [] with GeneAnnot based custom CDF (gahgu133plus2 v2.2.1) []. The log-2 normalized intensities were adjusted for batch effects by using ComBat function of the sva Bioconductor package []. The cmdscale functio […]


Transcriptional, epigenetic and retroviral signatures identify regulatory regions involved in hematopoietic lineage commitment

Sci Rep
PMCID: 4837375
PMID: 27095295
DOI: 10.1038/srep24724

[…] orescence signals to log2 expression values, we used the robust multi-array average procedure RMA of the Bioconductor affy package and the HG-U133 Plus 2.0 custom Chip Definition Files (CDF) based on GeneAnnot. We used Principal Component Analysis (PCA) coded by the prcomp function of the R stats package to verify the reproducibility of the 3 biological replicates. We used DNA-Chip Analyzer (dChip […]


Improving Cancer Gene Expression Data Quality through a TCGA Data Driven Evaluation of Identifier Filtering

Cancer Inform
PMCID: 4686346
PMID: 26715829
DOI: 10.4137/CIN.S33076

[…] to a different chromosome, strand, or are part of a gene cluster that could cause cross-hybridization. The CDF file can be obtained from test three filters utilizing Geneannot, a database of gene expression annotations and quality that evaluates the Affymetrix probesets on the following criteria. For each of the probesets on the Affymetrix chip, sensitivity, speci […]


Genome Wide Definition of Promoter and Enhancer Usage during Neural Induction of Human Embryonic Stem Cells

PLoS One
PMCID: 4433211
PMID: 25978676
DOI: 10.1371/journal.pone.0126590

[…] ording to the manufacturer protocol (Affymetrix, Santa Clara, CA). Signals were converted to expression values by the RMA algorithm [] and HG-U133 Plus 2.0 custom Chip Definition Files (CDF) based on GeneAnnot []. Differentially expressed genes were identified by Significance Analysis of Microarray method (SAM, []) setting the q-value [] threshold equal to 0 (or ≤0.01) and considering fold change […]


RUNX1/ETO blocks selectin mediated adhesion via epigenetic silencing of PSGL 1

PMCID: 5399174
PMID: 25867177
DOI: 10.1038/oncsis.2015.6

[…] A). Hybridization and image acquisition followed official Affymetrix protocols. No cell sorting was performed. For probes to probe set annotation, we used custom chip definition files (CDFs) based on GeneAnnot version 2.0, synchronized with GeneCards Version 3.04 (available at These CDFs decrease the total number of probe sets (one probe set per gene), and potent […]
