Upstream regulators analysis using Ingenuity Pathway Analysis for the HR and LR vaccinated pigs. A common approach to interpreting gene expression data is gene set enrichment analysis based on the functional annotation of the differentially expressed genes (Figure 13). With Ingenuity Pathways Analysis you can summarize a variety of biological information around your gene of interest. The gene list was loaded, and the source of the organism was filtered as only “Homo Sapiens”, so that the analysis of interactions and pathways was limited to humans. 1252 0 obj <>stream − log10(.001) > 3. Red bars depict positive z-scores while green depict negative z-scores. �M $��4�,�uی-� 0 ǋ8� Genes were categorized into functional clusters and network analysis was done by Ingenuity Pathway Analysis (IPA).

Figure 1. Canonical Pathway Z-scores Allows you to quickly determine if Canonical Pathways, including functional end-points, are increased or decreased based on differentially expressed genes or proteins in your data set Certain pathways within the knowledge base are directional (proceed from “A” to “Z”) To choose the best pathway analysis method, one should consider the following four crucial factors in order of importance: (i) number of biased pathways; (ii) ranking of the target pathways; (iii) AUC, accuracy, sensitivity, and specificity; and finally (iv) p values of the target pathways.
