  1. Protein degradation and exosomal secretion in controlling cancer cell signaling and tumor immune microenvironment

    We are interested in how cells ensure a balance between lysosomal degradation and exosomal secretion, how protein ubiquitination impacts on this balance, and how cancer cells perturb this balance to potentiate tumor malignant phenotypes and immunosuppressive tumor microenvironment. These regulatory mechanisms will be exploited for designing new anti-cancer strategies.

  2. Targeting proteasomal and lysosomal degradation of oncoproteins for anti-cancer therapy

    “Degradation” has emerged as a new concept of anti-cancer strategy and offers several advantages over the traditional “inhibition” strategy. We are interested in uncovering new proteasomal and lysosomal degradation pathways and/or strategies for several major oncoproteins.

  3. Regulation of cancer metabolism by biomolecular condensates

    Biomolecular condensates are intracellular membraneless compartments assembled through liquid-liquid phase separation arising from weak interactions among proteins and nucleic acids. Dysregulation of biomolecular condensates has been linked to disease states such as neurodegeneration and cancer. We are interested in the assembly/disassembly mechanisms and compositions of the biomolecular condensate that impacts on cancer metabolism.
