Tissue-specific patterns of mRNA association modules. Each row represents the tissue-specific pattern of a module. Red: coherent up-regulation in a tissue type. Green: coherent down-regulation in a tissue type. Black: incoherent expressions in a tissue type. Cis-acting modules range from 1 to 43. Trans-acting modules range from 44 to 84.
