Living organisms have ingenious control mechanisms in which many molecular interactions work for keeping their normal activities against disturbances inside and 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 and 65.5 % of non-debacle points can be predicted by the proposed method.
生物有机体拥有巧妙的控制机制,其中许多分子相互作用协同工作,以维持其正常活动,抵御内外干扰。然而,与此同时,这种控制机制存在崩溃点,在这些点上稳定性很容易被打破。本文提出了一种新方法,该方法利用递归神经网络在生物途径的混合功能Petri网模型中预测崩溃点。对细胞凋亡信号通路的评估表明,所提出的方法能够预测96.5%的崩溃点和65.5%的非崩溃点的发生率。
