  1. The genome-wide gene expression profile was studied on Human Gene 1.0 ST array in U373MG cells following a 24 hour-exposure to the vehicle (DMSO) or to the three chemical compounds (Figure 1). By importing the complete list of Entrez Gene IDs of downregulated or upregulated genes into the Functional Annotation tool of DAVID, the KEGG pathways related to the set of imported genes showing p < 0.01 by a modified Fisher Exact test were identified. The pathways are listed with the category, p-value, and false discover rate (FDR %).
