Molecular analysis of the interplay between tumor microenvironment and cancer progression

      Cancer is one of the major causes of death worldwide and has a significant impact on national health. During cancer progression, tumor cells are confronted with platelet and various plasma proteins in the bloodstream that has been defined as the third microenvironment in addition to the primary tumor site (the primary tumor microenvironment) and the distant metastatic organs (the second tumor microenvironment). Experimental and clinical data all indicate that tumor cell interacting with platelets and the clotting system are important elements of tumor progression and cancer cells metastasis leading to the development of advanced stage cancer. Abrogation of cancer cell-platelet interaction thereby provides an attractive target for development of innovative cancer therapeutic regimens. We aim to identify novel regulators that are crucial for cancer cell-platelet interactions using various molecular and cellular approaches. A number of in vivoand in vitro study models have been established that can be applied for target gene discovery and analysis. Several regulators that mediate cancer cell-platelet interactions are candidates for translating to clinical application and are under intensive investigation.

Molecular analysis of platelet function and platelet biogenesis

      Platelet is important in various physiological and pathological conditions, including hemostasis, thrombosis, and cancer. Understanding the mechanistic insight of platelet biogenesis and signaling can contribute to the development of effective therapy for thrombosis, thrombocytopenia, and cancer. Although it has been known for years that each megakarycoyte produces about 5000 platelets through the formation of proplatelet with thin tread structure protruding from the megakaryocytes, the key regulators in the control of megakaryocytic differentiation and platelet biogenesis are not yet completely understood. At present, the murine embryonic stem cells-OP9 coculture system and the lineage-specific DAB2 knockout mice are used as the study model to elucidate the functional role of the adaptor protein Disabled-2 (DAB2) in the regulation of megakaryocytic differentiation, proplatelet formation and platelet function. We expect to gain new insight on the mechanisms underlying megakaryocytic maturation and platelet biogenesis that should provide information on how functional platelets are produced in physiological condition and how to obtain and maintain appropriate platelet count underpathological condition.
