Integrating transcriptional profiling results from 2-way supervised and unsupervised analyses. (A) Relationship between genes that were identified from the expression profiling dataset by 2-way supervised pairwise comparisons or through unsupervised quantitative analysis with cellular parameters using PC1 at an FDR of 0% or < 5%. The numbers in the Venn diagram show the number unique to that set or in the overlap between sets. The positions of certain genes in these overlapping gene sets are indicated. (B) Classification of the combined gene list into biologic process categories by gene ontology analysis using the PANTHER tool. Only categories that are significantly enriched (P < .05) relative to all the genes in the human genome are shown. The y-axis denotes the number of genes that belong to each biologic process category that is significantly enriched.
