Research

Research Interests:

Dr Wan’s research focuses on cell-cell junctions in health and disease. Cell-cell junctions are multiprotein adhesion complexes located on the plasma membrane of the cell and play an essential role in cell adhesion and the maintenance of tissue integrity. These junctions crosstalk one another and coordinate with a diversity of cellular processes such as proliferation, differentiation, morphogenesis, as well as cell motility. Alterations of these junctions can lead to a broad spectrum of human diseases, including cancer and vesiculobullous conditions. Increasing evidence indicates that many components of these junctions also participate in cell signalling and are acting as sensors to the environmental biochemical and mechanical cues.

Her recent studies have identified Desmoglein-3 (Dsg3) acting as an anti-stress protein via regulating the mechanosensor YAP, cancer suppressor p53, as well as AP-1 transcription factor, that have a direct impact on the cell fate decision. These findings underscore the unprecedented role of Dsg3 in the control of higher-ordered network essential for tissue regeneration and homeostasis beyond cell-cell adhesion. Elucidation of the underlying molecular basis is crucial to understand the pathogenesis of the associated disorders such as cancer and pemphigus autoimmune disease in which Dsg3 is altered.

Dr Wan’s research approach is mainly based on in vitro studies with both gain and loss of function strategies in conjunction with the pharmacological interventions in keratinocyte cells derived from both the skin and oral mucosal membrane. The ultimate goal of her research is to translate the significant findings to clinical research to improve the diagnosis and treatment of related diseases.
