significantly affected (Figure 1). Figure 2 shows a simplified composite of all genes identified by IPA as being part of specific signalling pathways that are most significantly regulated, together with their individual S scores. Here the central mediator is the NF-κB signalling pathway that is clearly contributory in affecting the signalling through the Death Receptor, IL6, IL10, Toll-like receptor and PPAR pathways (also see Gene Networks section below and Figure 3 which also features NF-κB). In addition, several other canonical signalling pathways, some of which do not feature NF-κB, were also identified as significantly affected. Figure

1 Canonical Signalling Pathways identified by IPA software as significantly regulated by C. jejuni BCE. A Fisher’s exact test was used to calculate a p-value (Bars) determining the probability that the association between the genes in the dataset and the canonical pathway can be explained by chance Dipeptidyl peptidase alone. Threshold refers to the cut off for p < 0.05. Figure 2 Regulated molecules in canonical signalling pathways identified by IPA. Individual pathways are identified by colours assigned in the black-backed heading at the top. Significantly up-regulated genes are shown in darker colour. Significantly down-regulated genes are shown stippled. Numerical values beside regulated genes show the S score. All genes identified by the IPA programme as significantly regulated have been included, together with a limited number of non-regulated genes to portray a simplified view of pathway continuity.
