Figure 2: Functional classification of genes altered in PBMCs exposed to B. anthracis spores. The fractions of the enriched terms are displayed inside the parenthesis. The functional classifications for the parent terms are obtained using the GO analysis tool in GeneSpring v. 10.1. (A) Among the “Biological processes”, the “Physiological process” is the dominating annotation, followed by “Biological process regulation”, “Response to stimulus” and “Development”. “Other” includes “reproduction”, “growth” and “viral life.”(B) Under the parent term “Molecular function”, the “Binding” emerges as the dominating annotation followed by “catalytic and signal transduction activity”. “Other” includes “structural molecular activity”, “motor activity” and “translation regulator activity.”
