The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Cell Surface Mucins In Gastrointestinal Mucosal Innate Immunity

Summary
Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. We have recently identified three of the seven genes currently known to produce this type of molecule. We propose that mucins have a very important role in maintaining the barrier between potentially infectious microorganisms often present in epithelial tracts and the internal organs. We also believe t ....Epithelial cell surface mucins are large complex proteins found on the surface of all mucosal epithelial tissues, for example in the respiratory, gastrointestinal, reproductive and urinary tracts. We have recently identified three of the seven genes currently known to produce this type of molecule. We propose that mucins have a very important role in maintaining the barrier between potentially infectious microorganisms often present in epithelial tracts and the internal organs. We also believe that these molecules trigger epithelial cell defensive responses to the presence of microorganisms. The proposed research aims to prove these propositions and to elucidate the molecular mechanisms underlying function of cell surface mucins. Understanding the function of cell surface mucins could lead to the development of new drugs to treat epithelial inflammation such as that seen in inflammatory bowel diseases and respiratory diseases such as asthma and cystic fibrosis.Read moreRead less
Functions Of FZD7 In The Intestine And Colorectal Cancer

Summary
Wnt proteins are a family of signaling molecules that are critical for the function of normal and cancerous epithelial cells in the gut. However, the cell surface receptor that transmits Wnt signals is not known. Our research strongly implicates one Wnt receptor (FZD7). Here we test this using innovative mouse and cell line models. We wish to understand how Wnt-driven processes are activated. This knowledge will lead to novel avenues to block aberrant activation of Wnt signalling in cancer cells
My basic science and translational research centres around elucidation of the function of the mucosal barrier in preventing infection, inflammation and development of cancers, and how defects in this barrier lead to these diseases.
The Role Of Capsulin, A New BasicHelix-Loop-Helix Factor, In Differentiation And Repair Of The Gastric Mucosa.

Summary
We aim to understand the role that a new factor plays in the processes whereby the lining of the stomach is continually renewed, and also repaired after injury due to inflammation and ulceration. Once we understand the role of this factor and how it works, we may be able to use this factor as a therapeutic to prevent the initial formation of inflammation and ulceration in the stomach that can lead to more serious diseases, such as cancer.
