Protein interaction network was created using STRING. A 100 node network was obtained from an input set of 103 differentially expressed genes identified by Cuffdiff with an FDR < 0.05. The line thickness represents the strength of the data to support the interaction, including text mining, experimental, database, co-expression, neighborhood, gene fusion, and co-occurrence sources. The minimum required interaction score was set to 0.4. Shell parameters were set to “None”. Disconnected nodes are not shown. Cluster colors are based on the Markov Cluster Algorithm with the inflation parameter set to 2
