Abstract
Living organisms have ingenious control mechanisms in which many molecular interactions work for keeping their normal activities against disturbances inside arid outside of them. However, at the same time, the control mechanism has debacle points at which the stability can be broken easily. This paper proposes a new method which uses recurrent neural network for predicting debacle points in an hybrid functional Petri net model of a biological pathway. Evaluation on an apoptosis signaling pathway indicates that the rates of 96.5% of debacle points arid 65.5% of non-debacle points can be predicted by the proposed method.
