生物化学网络中噪声诱导的亚稳态

Noise-induced metastability in biochemical networks

Tommaso Biancalani, Tim Rogers, Alan J. McKane

摘要:

细胞内的生化反应表现出丰富的动力学现象,不能解释的框架内的平均场速率方程和加性噪声。在这里,我们表明,存在的亚稳态和根本上不同的时间尺度的一般功能的一个广泛的类的autocatalyic反应网络,而且,这一事实可能会被利用,以获得分析结果。后一点是证明了治疗的典范渡桥金子反应,这在过去的十年里一直抵制理论分析。

英文摘要:

Intra-cellular biochemical reactions exhibit a rich dynamical phenomenology which cannot be explained within the framework of mean-field rate equations and additive noise. Here, we show that the presence of metastable states and radically different timescales are general features of a broad class of autocatalyic reaction networks, and moreover, that this fact may be exploited to gain analytical results. The latter point is demonstrated by a treatment of the paradigmatic Togashi-Kaneko reaction, which has resisted theoretical analysis for the last decade.
