Research Interests

The appropriate subcellular localization of proteins is crucially important to provide the physiological context for their cell function. Aberrant localization of proteins has been shown to contribute to the pathogenesis of many human diseases including metabolic, cardiovascular, neurodegenerative diseases and cancer and serves as valuable diagnostic or prognostic marker (Hung and Link, Journal Cell Science 124, 3381). The temporal and spatial regulation of protein localization has been shown to be particularly important for cancer stem-cells biology. Many important tumour suppressors and oncoproteins exert their functions in a specific cellular compartment. Aberrant localization of tumor suppressor proteins has been proposed to be a more generalized mechanism for their inactivation in human cancer. Hence, the therapeutic restoration of normal protein location targeting components of the signaling networks responsible for the inactivation of nuclear tumor suppressors has achieved considerable attention. Conversely, pharmaceutically induced mislocalization has been considered as a promising therapeutic strategy for targeting oncoproteins. There is a significant number of emerging technologies such as “high content screening” attempting to deal with the complexity of intact cells that allow for the unbiased characterization of critical nodal points in the signaling circuits that regulate protein localization. Understanding this process will likely be critical for identifying small molecule compounds or relevant therapeutic targets that might be exploited pharmaceutically to restore or interfere with protein localization and function.

Based on previous work characterizing regulatory signalling networks involved in subcellular translocation of the tumor suppressor FOXO3a, Dr Link's research will focus on the characterization of previously identified FOXO suppressors, the identification of novel indications of existing drugs that restore localization and function of FOXO proteins using image-based reprofiling and the application of the similar technological approaches to analyze regulatory signalling network involved in subcellular translocation of other tumor suppressors and oncoproteins.
