Research Interest Statement:
My research is investigating the pathophysiology of multiple myeloma (MM), a B cell cancer characterized by proliferation of malignant plasma cells in the bone marrow, presence of monoclonal serum immunoglobulin, and osteolytic lesions. MM studies demonstrate that MM causes severe lytic bone lesions by enhancing osteoclast activity/suppressing osteoblast activity. We are studying the factors of bone metabolism that may influence MM growth. We are also interested in the early detection of MM induced bone disease (MMBD). The current methods focused on either MM cell activity or structural damage of bone. Our recent clinical observation demonstrated that a significant portion (43%) of MMBD patients heal the large bone lesions after therapy while the rest do not. It leads us to hypothesize that MMBD may be cured by the treatment when they are on the right stage, thus MMBD may need to define stages based on the status of osteolysis process. We employed a newly developed collagen hybridizing peptide (CHP) to detect collagen degradation that is an early stage on the process and demonstrated that in situ imaging with CHP detects MMBD and highly correlated with MM cell numbers. Currently, we are defining the MMBD stages that CHP detects during MM development. Additionally, we have been developing various Patient-Derived Xenograft (PDX) mouse models from MM, Lymphoma, and non-small cell lung cancer. We have developed a unique humanized mouse strain that is susceptible to human tumor cells/tissue. We have been successfully developing various PDX models.
