Figure 7From: cDNA targets improve whole blood gene expression profiling and enhance detection of pharmocodynamic biomarkers: a quantitative platform analysisConcordance between canonical SAHA signature and the signature identified by the ex vivo profiling method. 50% of the canonical SAHA signature (336 genes) is represented on the custom Affymetrix GeneChip array, with a p < 0.01. More than 90% of the genes are regulated in the same direction between the two datasets.Back to article page
