Jianguo Tao, MD, PhD
Academic Rank: Senior Member
Dr. Tao is a trained hematopathologist and physician-scientist who is well versed in both basic and translational studies in hematologic tumors, with special interest and emphasis in B-cell malignancies: genetic and epigenetic mechanisms of microenvironment-induced survival and drug resistance in B lymphomas. For the last decade, his laboratory has independently studied the role of stroma-mediated B-cell lymphoma survival, drug resistance and tumor progression. His team has demonstrated that the lymphoma “tumor microenvironment” is a critical determinant for lymphoma initiation, progression, response to therapy, and drug resistance. His long-term objective is to characterize the pathobiology of B-cell lymphomas, especially aggressive type B cell malignancies. He is interested and experienced in identifying major molecular determinants for drug response and resistance, as well as novel targets for overcoming or preventing drug resistance evolution in mantle cell lymphoma and double hit lymphoma (DHL).

Dr. Tao’s laboratory focuses on: 1) functional genomics and biomarkers of lymphoma; including microRNA expression profile in selected lymphoma subtypes (mantle cell lymphoma and viral-associated lymphomas) to determine possible involvement of microRNAs in the pathogenesis of non-Hodgkin lymphoma and their possible role in diagnosis, prognosis and therapeutic target discovery, 2) microenvironment regulation of molecular pathogenesis of lymphoma; his laboratory is studying the normal development of germinal center B cells.His team aims to determine microenvironment regulation of normal and abnormal transcriptional factors and miRNAs involved in B-cell differentiation, activation and lymphomagenesis, 3) Microenvironment regulation of drug resistance of lymphoma. The team’s recent studies have shown that adhesion of lymphoma cells to bone marrow stromal cells significantly increases cellular resistance to a variety of cytotoxic drugs and induces cell cycle arrest. They have extended this research to determine the role of the interaction between lymph node stromal cell and lymphoma cells as well as miRNAs in response to therapy and to further elucidate the molecular mechanisms by which stroma regulates lymphoma cell survival.
