Finding VulnerabilityVulnerability assessment methods, which are commonly used to test digital circuits, were applied to biological signaling networks to identify the molecules that when dysfunctional, would be most likely to disrupt the function of the network. Two signaling well-characterized networks were analyzed (one leading to caspase3 activation and apoptosis and a second leading to activation of p53) and the molecules known to be critical to the response were properly identified. In a third network of neuronal activation of the transcription factor CREB, this analysis led to the identification of Gi and the P/Q-type calcium channel, which were then experimentally validated as critical molecules in this network.
