Abstract:
|
While many methods have been developed for differential expression analysis using single cell RNA-seq data, there is a lack of methods to infer gene regulatory networks (GRN) using these data. In this presentation, we described a statistical approach to the inference of gene regulations based on the estimated pseudotime and cell lineages through single cell RNA-seq data while incorporating prior knowledge. Our method can handle both linear and nonlinear regulations. We demonstrate the usefulness of our approach through its application to monocyte-macrophage differentiation and T-cell lineage for samples collected from both the Idiopathic Pulmonary Fibrosis (IPF) and Chronic Obstructive Pulmonary Disease (COPD) patients. We show that our new method can better identify the differential gene regulations in IPF and COPD patients compared with healthy controls.
