Murphy Lab

Welcome to the Murphy Lab


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. Presently, it is unknown what molecular machinery allows a cell to transition from one gene expression state to another.

In the Murphy laboratory, we use the zebrafish model, mammalian stem cells, and human cancer cell lines, to investigate how epigenetic marks control gene expression patterns, and drive cell state transitions. This work relies on classic genetics and developmental biology methods, new DNA sequencing technologies, and bioinformatics applications, to map the genomic locations of various proteins and epigenetic marks as they change during cell state transitions.
