Professional Interests

For most cancers, the cause of patient death is either local invasion into critical areas or metastasis - dissemination of tumor cells from the primary tumor to many parts of the body followed by formation of new tumors at those distant sites. By understanding the mechanisms by which tumor cells invade and metastasize, we will have better chances of developing appropriate therapies. Tumor cell motility and the orientation of tumor cells by chemotaxis make important contributions to invasion and metastasis.  Three types of cancer are being studied.  Glioblastoma and head and neck cancer invade locally into critical areas and the primary tumors are not fully removable by surgery.  Breast cancer, although the primary tumor can be fully removed, metastasizes to distant sites, and the resulting metastases can lead to poor prognosis.  Tissue culture studies of invasion and signaling of these cancers are combined with in vivo analysis in mice.
