Dr. Doble’s research program is focused on understanding the signaling mechanisms that maintain embryonic stem cells in a pluripotent self-renewing state versus those that promote their differentiation into specialized cell types. He is particularly interested in understanding how signals are relayed through cells via changes in the phosphorylation status of signaling molecules. Enzymes called kinases are responsible for phosphorylating proteins, often dramatically changing the function of the protein targets.
Of particular interest to the Doble lab is the multifunctional protein kinase, glycogen synthase kinase-3 (GSK-3). GSK-3 controls the function of many cellular processes, and is strongly linked to the regulation embryonic stem cell self-renewal and differentiation. GSK-3 is a central regulator of the developmentally important Wnt/b-catenin signaling pathway, which likely plays a large part in GSK-3’s regulation of stem cells.
The current projects in the Doble lab are focused on understanding the mechanisms through which GSK-3 and Wnt/b-catenin signaling regulate embryonic and adult stem cell properties. Understanding the unique properties of stem cells is important if they are to be safely used as sources of differentiated cells for regenerative medicine purposes. As well, insights into the mechanisms regulating stem cell self-renewal has the potential to be applied to cancer therapies, since the same self-renewal pathways utilized by stem cells are “hijacked” by cancer cells.
