Cell type-specific gene expression profiles in the prostate gland were assessed with the NCBI GEO dataset GDS1973 [19 (link)], which was generated from four different cell types using an antibody pulldown approach against distinct cell surface-specific markers. There were five biological replicates of each pulldown assay, and the expression profiles were determined using the Affymetrix U133 Plus 2.0 arrays. The expression levels of candidate genes were normalized using the β-Actin (ACTB) gene as the internal control.
