摘要:

确定基因调控网络(GRN)结构是生物学中的一个核心问题,针对不同类型的数据已有多种推断方法。对于一个广泛存在且具有挑战性的用例,即在多个时间点干预后测量的、联合分布未知的单细胞基因表达数据,目前仅有一种专门开发的方法,且该方法未能充分利用该数据类型中包含的丰富信息。针对这种情况,我们开发了一种GRN推断方法,即基于协方差动力学的网络推断(netWork infErence by covariaNce DYnamics),简称WENDY。WENDY的核心思想是对协方差矩阵的动力学进行建模,并将该动力学作为优化问题求解,以确定调控关系。为了评估其有效性,我们使用合成数据和实验数据将WENDY与其他推断方法进行了比较。结果表明,WENDY在不同数据集上均表现良好。

英文摘要:

Determining gene regulatory network (GRN) structure is a central problem in biology, with a variety of inference methods available for different types of data. For a widely prevalent and challenging use case, namely single-cell gene expression data measured after intervention at multiple time points with unknown joint distributions, there is only one known specifically developed method, which does not fully utilize the rich information contained in this data type. We develop an inference method for the GRN in this case, netWork infErence by covariaNce DYnamics, dubbed WENDY. The core idea of WENDY is to model the dynamics of the covariance matrix, and solve this dynamics as an optimization problem to determine the regulatory relationships. To evaluate its effectiveness, we compare WENDY with other inference methods using synthetic data and experimental data. Our results demonstrate that WENDY performs well across different data sets.
