Research Overview:     

       Over 90% of solid tumors are aneuploid. The long-term goal of our research is to understand and control aneuploidy and chromosomal instability in cancers. To that end, we have been investigating both subcellular structures (the centromere/kinetochore complex) and regulatory mechanisms (the mitotic checkpoint) involved in chromosome segregation during cell division (mitosis). As recent results suggested that aneuploid cancer cells acquire additional genetic or epigenetic alterations to survive and proliferate, we also aim to identify recurring modifications in aneuploid cancer genomes and test whether they can be used for cancer prognosis and treatment.
        Even though many cancer "signature" genes have been proposed, the biological functions of some “signature” genes remain obscure. We currently focus on characterizing certain chromosomal instability (CIN) signature genes in breast cancers. During the process, we have realized the limitations of regular 2D cell culture therefore are incorporating different 3D cell culture systems and animal models into our research.
        Inquiries to join the lab as undergraduate, graduate or postdoctoral researchers are always welcome. Lab visits can also be arranged for K-12 students, parents and teachers or anyone who is interested in our work. Please see our Lab Website for more information. The lab has been financially supported by the University of Toledo, deArce Memorial Fund, Ohio Cancer Research Associates, Ohio Board of Regents, National Science Foundation (NSF) and National Institutes of Health (NIH).
