Title: Gene regulatory networks and stable cellular states
Abstract: A stable cell type is believed to be maintained by a set of regulators that work together, as a gene regulatory network, to control the transcriptional state of the cell. In this talk I will provide a mathematical formulation that relates the concept of a gene regulatory network to an underlying equation that governs the time evolution of the cellular state.
Based on this formulation I will outline an approach for the study of the network through gene perturbation experiments. Finally I will introduce a statistical method for the analysis of data from such perturbation experiments, and demonstrate how it works in the estimation of the gene regulatory network of embryonic stem cells.
