Research Interests
WOUND HEALING
Poor healing wounds represent a silent epidemic that affects a large fraction of the world population and carries a heavy socioeconomic burden. Despite the enormous impact of these poor-healing wounds, effective therapies remain lacking. Effective management of these problems will require better understanding of the healing process to allow the creation of a salubrious environment conducive to healing. Our lab has worked extensively to understand the transcriptional regulation of skin wound healing and particularly the interplay among different cell types during wound healing. We identified angiopoietin-like 4 protein (ANGPTL4) as a novel matricellular protein that is essential for proper wound healing. Wound healing in ANGPTL4-knockout mice are delayed and share many characteristics of poor healing wounds, including increased/prolonged inflammation, impaired wound-related angiogenesis and ruined extracellular matrix. Hyperproliferative wound keratinocytes secrete high amount of ANGPTL4 which plays a major role in cell-cell communication, and cell-matrix interactions in many aspects of wound healing including re-epithelialization, angiogenesis and scar formation. A cardinal feature of poor healing wounds is a persistent inflammatory response at the wound site. Thus, our current studies is to investigate the role of immune-associated reactive oxygen species on wound healing.

TARGETING METASTASIS
Metastasis accounts for more than 90% of cancer mortality. Once metastasis occurs, surgical excision of the primary tumor no longer guarantees disease free survival and the probability of cancer relapse in distal organs increases significantly. Although most cancer deaths are the result of metastases, cancer research has mainly focused on the primary tumor. Our interest on how cancer cells survived in the circulation led to our discovery of an ANGPTL4-Nox1-ROS axis responsible for conferring anoikis resistance. Our findings have established several paradigms in oxidative stress-driven metastasis. Tumor cells become migratory and invasive via epithelial-mesenchymal transition (EMT). My lab has actively interrogated the molecular changes in cancer cells during EMT. We showed that EMT is an energy-demanding process and that metabolic changes during EMT are critical to sustain an elevated adenylate energy charge needed to fuel various biological processes, such as invasion and chemoresistance. We identified ANGPTL4:YWHAG signalling axis coordinates cancer cell metabolic activities with EMT. Our current interest aims to decipher the mechanisms that regulate and coordinate the different networks during EMT which will provide much-needed insight into the process of metastasis. Deliberate disruption of these mechanisms is expected to yield important clinical information regarding etiology, prognosis and response to therapy.
