    Research Overview

  • The objectives in Dr. Xu's lab are to identify the molecular mechanisms underlying tumor suppressor function and to develop pharmacological agents that can modulate or mimic tumor suppressors for cancer prevention and treatment. Specifically, the lab currently has three research directions:
    (1) Tumor suppressor and genomic stability: (A) To investigate mechanisms of how tumor suppressors, such as LKB1 (also known as serine/threonine kinase 11, STK11), PML, and p53, regulate genomic stability; (B) To determine LKB1-related protein signatures and signaling networks under stressed conditions and identify novel LKB1-interacting proteins; (C) To define LKB1 expression (mutation) in tumors and its relationship to patient outcomes and therapeutic response.
    (2) Cell death---Autophagy and Necrosis: (A) To determine the role of autophagy in LKB1-mediated genomic stabilization; (B) To screen and characterize genes that regulate autophagy and necrosis in mammalian cells; (C) To determine the role of autophagy and necrosis in tumorigenesis and targeted therapy.
    (3) Molecular therapeutics: To develop pharmacologic agents targeting the LKB1-AMPK-mTOR pathway for cancer prevention and treatment.
