Tissue-specific co-expression networks. Nodes are genes and edges reflect co-expression defined by our algorithm (see Methods). Co-expression of candidate genes in artery (a), blood (b), and both artery and blood (c) show similar structure between the two tissues with little overlap in particular gene pairs. Edges within a single gene indicate co-expression between isoforms of the same gene. Note: not all expressed isoforms are co-expressed
