Data were normalized to the HPRT housekeeping gene. P values were derived from ANOVA of microarray data. Values for microarray data are fold-regulation. For each quantitative PCR (qPCR) experiment, values were determined by measuring samples in duplicate at multiple concentrations (mean ± standard error). Each experiment was performed independently at least three times.
