Wayne State University Dissertations
SUMOylation is an essential post-translational modification that regulates a variety of critical cellular pathways ranging from nuclear transport to protein stability. Accumulating lines of evidence have shown that a perturbation of the SUMOylation pathway is associated with human diseases, especially various types of cancer. Our recent proteomic studies revealed a drastic increase in levels of SUMO2/3 modification on the proinflammatory cytokine MIF in the metastatic breast cancer cell line compared to the non-metastatic control cell line. Interestingly, the increase in levels of both MIF and global SUMO-2/3 modification in the metastatic cells are positively correlated to that of unmodified MIF …
