基因表达动力学与调控推理问题

Dynamics of gene expression and the regulatory inference problem

Johannes Berg

摘要:

从对外界刺激的反应到细胞分裂和死亡,活细胞的动力学是基于特定基因在特定时间的表达。何时表达基因的决定是通过转录因子分子与调节DNA的结合和解结合来实现的。在这里,我们构建随机模型的基因表达动力学和信使RNA浓度的实验时间序列数据进行测试。该模型用于推断基因转录的生物物理参数,包括转录因子-DNA结合的统计和由给定的转录因子控制的靶基因。

英文摘要:

From the response to external stimuli to cell division and death, the dynamics of living cells is based on the expression of specific genes at specific times. The decision when to express a gene is implemented by the binding and unbinding of transcription factor molecules to regulatory DNA. Here, we construct stochastic models of gene expression dynamics and test them on experimental time-series data of messenger-RNA concentrations. The models are used to infer biophysical parameters of gene transcription, including the statistics of transcription factor-DNA binding and the target genes controlled by a given transcription factor.
