摘要:

破译基因调控网络是计算生物学的核心问题。在这里,我们探讨使用多模态神经网络学习预测模型的基因表达,包括顺式和反式调节组件。我们学习模型的压力反应在芽殖酵母酿酒酵母。我们的模型实现了高性能,并大大优于其他最先进的方法,如使用预定义的顺式调控功能的提升算法。我们的模型学习了几个顺式和反式调节器,包括著名的主应激反应调节器。我们使用我们的模型来执行在硅片TF敲除实验,并证明,在硅片预测的靶基因的变化与相应的TF敲除微阵列实验的结果。

英文摘要:

Deciphering gene regulatory networks is a central problem in computational biology. Here, we explore the use of multi-modal neural networks to learn predictive models of gene expression that include cis and trans regulatory components. We learn models of stress response in the budding yeast Saccharomyces cerevisiae. Our models achieve high performance and substantially outperform other state-of-the-art methods such as boosting algorithms that use pre-defined cis-regulatory features. Our model learns several cis and trans regulators including well-known master stress response regulators. We use our models to perform in-silico TF knock-out experiments and demonstrate that in-silico predictions of target gene changes correlate with the results of the corresponding TF knockout microarray experiment.
