            Although protein-protein interaction networks are an ubiquitous component of modern systems biology, comparatively few efforts have been made to tailor their topology to the actual cellular condition under study. Since a simple reduction of the networks to the subset of expressed genes only scratches the surface of higher organisms’ regulatory capabilities, we propose the advanced method PPIXpress that allows to exploit expression data at the transcript-level and is thus able to also reveal...
