Fig. 7

Gene–gene and protein–protein interaction network of selected candidate genes. A Each node represents an enriched GO term. Related GO terms are connected by a line, whose thickness reflects percent of overlapping genes. The size of the node corresponds to number of genes. Darker nodes represent more significantly enriched gene sets. Bigger nodes represent larger gene sets. Thicker edges represent more overlapped genes. B Represent protein–protein interaction. Line thickness represent level of interaction (thicker line for strong interactions)
