ERK and Ras signaling pathways were hyperactivated in the biopsy CCA tissue. Visualization was provided by Oncobox software. The pathways are shown as an interacting network, where green arrows indicate activation, red arrows—inhibition. Color depth of each node of the network corresponds to the logarithms of the case-to-normal (CNR) expression rate for each node, where “normal” is a geometric average between normal tissue samples, the scale represents extent of up/downregulation. The molecular targets of Sorafenib and Pazopanib are shown by black arrows
