    Research Interests:

    1.Mechanism of mRNA polyadenylation and its role in gene expression regulation

    Messenger RNA polyadenylationis one of the critical steps in eukaryotic gene expression. The poly(A) tail of a mature mRNA is essential for its function, including mRNA translatability, stability and translocation to cytoplasm. The process also affects pre-mRNA splicing and transcription termination. Recent studies have linked mRNA polyadenylation to other cellular processes, e.g. pathogen invasion and cancer development.

    I am interested to elucidate mRNA polyadenylation mechanisms at genetic, transcriptome, and molecular levels. We have used functional genomic tools to study the functions of this set of genes in model plantArabidopsis. Funded byUS National Science FoundationandUS National Instate of Health, we have studied the biochemical, genetic and molecular functions of some polyadenylation factors, and their role in plant gene expression regulations in gametophyte development and stress responses.

    Aided by powerful RNA-sequencing technologies, we are performing large-scale analyses of alternative polyadenylation to discover the full landscape of polyadenylation from single cells to whole organisms. There are over 70% genes using alternative polyadenylation (APA) to regulate their expression. Role of such extensive APA in cells and organisms is just being revealed.Accompany with multi-omics tools, it has been demonstrated that APA are linked to many cellular processes, including circadian regulation of gene expression, epigenetic control, and quantitative traits, etc.The theme of APA as a hub of fine-tuning gene expression regulation at the transcriptome level has emerged.

    2.Role of exosomes in neuronal cell communication on Alzheimer and Alzheimer-like disease models using iPSC derived cells.

    My research interests are extendedto include gene expression regulation and communication of human iPSC (induced pluripotent stem cells), particularly in neuronal disease models like Alzheimer’s disease (AD).AD and related dementias are a global crisis facing the aging population.AD is characterized in part by massive neuronal loss in the brain. However, how these neurons get lost is not understood.

    Microglia,the resident immune cells of the central nerve system,have long been suspected to play a role in AD pathogenicity.The interactions among microglia, astrocyte, neuron and extracellular matrix significantly are influenced byextracellular vesicles (EVs). Generated by the endosomal system of a cell, EVs are lipid bilayer membrane vesicles, 30 to 200 nm in diameter.Their role involved in cell-to-cell communications is supported by the fact that EVscontain active biomolecules, including proteins, mRNA and miRNA that are capable of modulating gene expression in recipient cells.Microglia-derived microvesicles have been reported to regulate neuronal excitability too. Theyrepresent a relatively new field of research in neurodegenerative diseases.

    We have employed multi-omics tools to first study the components of the microglia derived EVs associated with specific AD-like model cells derived from patients and normal control individuals. Delineation of these potential markers and their functions in regulating gene expression, particularly related to neuronal degeneration, are of great interests. The results of these research could lead to new insight on neuronal gene expression regulation and offer potential targets for drug design in the near future.
