Figure 3.

Sample–sample network graph of microarray data. Normalized expression data for the top up-and down-regulated genes (P < 0.05, fold change ≥ 1.2) identified by microarray analysis were visualized using BioLayout Express^3D. Each node represents a different patient sample and edges are coloured to reflect the Pearson correlation that they represent. Red edges indicate high correlation, and blue edges represent low correlation. The same data set is used for each graph. (A) unbiased MCL cluster (MCLi = 20). (B) Nodes are coloured by gestation and labour status into our four sample groups: TNL (n = 11), TL (n = 9), PTNL (n = 7) and PTL (n = 8).
