Relative expression stability of 'popular normalizers' in the HRT study. Relative expression stability of genes commonly used as internal references for normalization (popular normalizers). Each dot represents one probe set. Data from ovariectomized rhesus macaques receiving hormone replacement. Values closer to zero (top of histogram) indicate greater expression stability. Microarray data from the amygdala, hippocampus and arcuate hypothalamus of ovariectomized rhesus macaques receiving E2 or E2+ P4 and evaluated using the Affymetrix® rhesus GeneChip®. The chart shows expression stabilities of 39 probe sets representing 15 popular genes. The ordinate axis shows expression stability rank relative to expression stabilities of 1444 probe sets representing 575 human genes reliably expressed under multiple conditions. Gene expression stability values were generated from gene expression values grouped according to either brain region or treatment group using NormFinder software.
