Research Interests

How do the key target proteins determine the status of cell differentiation and proliferation? How do the modifications of gene structure (DNA and core histone) cause global changes of gene expression pattern? My research employed multitude of molecular, cellular, physiological and bioinformatics techniques to investigate the molecular mechnisms and physiological function of interferon induced P202a, acute megakaryoblastic leukemia associated transcription factorRBM15, and Polycomb Repressive Group proteins SUZ12. The ongoing research topics including global interferes for binding pattern caused by fusion of polycomb protein JJAZ1 to transcription repressor JAZF1 and genome-wide exploration of cis regulatory regions bond with transcription factor JAZF1 using CHIP-sequencing analysis.
