Data processing
Genechip PrimeView Human Arrays were utilized (Affymetrix, Santa Clara, CA). CEL files were analyzed utilizing R/Bioconductor package, oneChannelGUI. Briefly, normalization of expression values was performed utilizing the “Expresso” option, selecting “RMA” as the background correction, “quantiles” as normalization, “pmonly” as the PM correction, and “MAS” as the expression. Probes were filtered with IQR settings of 0.25. P values were calculated using a two-tailed Student’s t-test.
