Visualization of the common gene coexpression network modules to identify hub genes. The eigengene in the common modules between the LT-blue and Lde-brown (A) and between LT-turquoise and Lde-turquoise (B) modules are shown. The top 300 connections are shown for each module. Dots correspond to genes and lines to connections; hubs genes have at least 15 connections. Where the gene symbols are unknown, gene IDs are shown (e.g., WE424869).
