Tissue-specific splicing regulatory network. Yellow diamonds stand for tissues. The size of diamond is proportional to the degree of connections with cis-acting RNA elements (CAEs). Nodes with different colors indicate CAEs in different regulatory regions (see legends). Connections between CAEs and tissues suggest the regulatory relationships. Red and blue lines indicate TSFL > 0 and TSFL < 0, respectively. The size of circle is proportional to the number of tissues connected to CAE.
