Epidermal growth factor (EGF) and heregulin (HRG) act via ErbB receptors, to stimulate Akt and ERK. These drive breast cancer cell proliferation and the network is targeted in cancer therapy (1). Single cell responses show marked cell-cell variation and information theory provides statistical measures that take the effect this noise has on information transfer into account (2). Here we quantify the mutual information (MI) between stimulus concentration and effects in MCF7 cell...
