HepG2 network. Perturbation networks were constructed with only significant edges (mean of ΔΔCT > 2 SD and P < 0.05). The regulatory edge with an arrowhead and blue line indicate a stimulatory edge. T-shaped heads and red lines indicate repressive regulation. Line widths indicate perturbation magnitude.
