Predicted network of interactions in skeletal muscle . Network of predicted TF interactions in skeletal muscle based on testing in 3-way contingency tables. Red nodes denote previously known regulators in skeletal muscle, green nodes indicate TFs expressed in skeletal muscle. TFs with known function in muscle are labeled with an asterisk. Red and orange edges denote known PPIs and known trios, respectively. Common co-factors which were included in the network but were not predicted are denoted by grey color and the corresponding interactions by grey edges.
