Patrick Murphy, PhD

About

The Murphy lab investigates the mechanisms that activate or silence genes as cells transition from one state to another. In very early embryos, stem cells begin to divide and change. Through this process, called differentiation, tissues start to form, and all the cell types of the organism begin to arise. Differentiation relies on a highly coordinated series of gene activation and silencing events. As cells divide during differentiation, changes in gene expression provide each cell type with a specific identity and function. In a similar sense, when the gene expression patterns of normal adult cells change inappropriately, the cell identity also changes, and this can lead to carcinogenesis.
