Figure 3. (A) Venn diagrams showing the number of differentially expressed genes and enriched pathways of gingival tissue and saliva sample. The intersection of the 2 circles refers to genes and pathways commonly detected in the results from the gingival tissue and saliva samples. There were 9 overlapping genes and 34 overlapping pathways between the tissue and saliva samples. (B) Interactive maps of overlapping GO biological process terms between the tissue and saliva samples. The size of each node represents the frequency of GO terms in the underlying GO annotation database and the thickness of the lines indicates similarity between GO terms. The length of the lines is arbitrary. The data suggest that immune response-related terms were prominent in overlapping pathways. The maps were visualized using REVIGO (http://revigo.irb.hr).
