Membrane trafficking and cancer signalling
PhD - State University of New York, Buffalo, NY, USA 
 

SUMMARY
Wanjin Hong is both a Professor at  the Institute of Molecular and Cell Biology (IMCB)  and Chief Business Development Officer, Biomedical Research Council (BMRC), Agency for Science, Technology and Research (A*STAR). 

Prior to his current appointment, he was the Executive Director of IMCB for over a decade. During his leadership from 2011-2023, IMCB has recruited and mentored a new generation of scientific leaders as PIs, sustained its research excellence with increasing external funding, increased collaborations within A*STAR research institutes and externally with universities and academic medical centres. In addition, IMCB has developed innovative technologies such as medical proteomics, humanized mouse models, 3D culture of organoids, mouse models of human diseases, advanced molecular histopathology and imaging analysis, to facilitate the scientists to define the underlying molecular and cellular mechanisms of major human diseases. Furthermore, IMCB has also increased meaningful collaborations with biotech and pharma companies while focusing on creation of A*STAR spin-off companies to contribute to the biotech ecosystem in Singapore. 

Apart from his leadership roles at A*STAR, Wanjin’s research lab focuses on protein trafficking to understand cellular organisation and cancer signalling pathways relevant to human diseases such as cancer. His early works identified over half of mammalian SNARE proteins, revealed Phox (PX) domain as a binding motif for PI3P, defined the role and mechanisms of small molecular GTPases such as Arl1, Rab7 and Rab34 in membrane trafficking.  

Wanjin’s recent focus on Hippo pathway enabled his lab to define TAZ as a new oncogene and its oncogenic function depending on interaction with TEAD transcriptional factors. His lab and collaborators resolved the crystal structures of YAP-TEAD, TAZ-TEAD and Vgll1-TEAD complexes, revealed the first time that TEADs have a hydrophobic pocket druggable by small molecule inhibitors, and identified flufenamic acid as the very first binder of the pocket. The breakthrough discoveries have facilitated biotech and pharma companies and academic community to develop inhibitors targeting YAP/TAZ-TEAD interaction and the hydrophobic pocket as cancer therapy with over 5 different inhibitors in clinical trials for cancer therapy.  He also serves on the Editorial Board of Science Signaling, TRAFFIC and Cell & Bioscience.

RESEARCH

The current research focuses in Wanjin’s lab include 1) Defining the roles & mechanisms of novel factors for the Hippo pathway with a focus on Agrin as a mechanic sensor for stuffiness of cancer tumor microenvironment in integrating Hippo pathway, USP9x, USP15, & USP22 deubiquitinases, UBR5 E3 ubiquitin ligase, and CIT kinase in regulating established Hippo components; 2) Identifying novel inhibitors/ activators and defining the mechanism of action of TEAD transcription factors for evaluation for cancer therapy or regenerative medicines; and 3) Defining the mechanism underlying the enhanced stability of EGFR mutants so that novel proteins (stabilizers) important for maintaining EGFR mutant stability can be discovered as drug targets, to destabilize EGFR mutants with the ultimate goal to discover novel therapeutic targets and leads for cancer therapy based on deep understanding of biology of cancer signalling pathways.

  • Dermatopontin as a therapeutic for metabolic disorders (SG11201706400WB/ WO2016130085A1)
    The present disclosure describes to a method of treating a metabolic disease in a subject, wherein the method comprises administration of dermatopontin to a subject, wherein the dermatopontin is recombinant dermatopontin and the metabolic disease is selected from a group consisting of weight gain, diet-induced weight gain, obesity, morbid obesity, metabolic syndrome, glucose homeostasis, insulin resistance, type I diabetes, type if diabetes and cardiovascular disease. Disclosed herein is also a method of determining or making a prognosis of a subject's susceptibility to metabolic diseases and obesity, the method comprising measuring the level of circulating dermatopontin in a sample obtained from a subject; and comparing the level of circulating dermatopontin obtained with the level of dermatopontin previously determined in a control; and determining the susceptibility of the subject to metabolic disease and obesity based on the difference between the level of circulating dermatopontin and the level of dermatopontin in the control.
