Summary
The mucin Muc1 is an important part of the barrier against infection in the gut, and appears to protect against development of bacterial inflammatory disease. We have identified that Muc1 suppresses activation of the inflammasome (a mechanism by which pathogens cause inflammation). We will now examine how Muc1 does this and explore the importance of this effect on inflammatory disease in the intestine. This may identify novel approaches for protecting against gastric and colorectal cancer.
Investigating The Effects Of Macrolides On Excessive Synthesis And Secretion Of Airway Mucins Using Novel Ex Vivo And In Vivo Approaches

Summary
Many people have difficulty breathing because the airway tubes that move air in and out of their lungs are blocked by excessive amounts of sticky mucus. Our project will use new techniques developed in our laboratories to investigate whether a group of medicines called “macrolides” can prevent the excessive production and release of mucus in the airways, and thus be beneficial in treating asthma, and potentially other lung diseases.
Disrupting Mucin-mucin Interactions To Treat Respiratory Diseases

Summary
Diseases like asthma, emphysema and cystic fibrosis all feature the overproduction of mucus in the lungs that make it very difficult for patients to breathe and increases their susceptibility to infections. Few therapies are available for thinning this mucus, which is made thick by a network of linkages between proteins. We are studying these linkages and developing methods to break them up. This research could yield new mucus-thinning drugs to treat lung diseases.
Cell Surface Mucins In Gastrointestinal Infection, Inflammation And Cancer Development

Funding Amount

Summary
Cell surface mucins are protective molecules that line all the wet surface of the body, including the gastrointestinal tract. Our research has uncovered that mucins regulate cell growth and cell death. Inappropriate control by the mucins, could lead to chronic inflammation and formation of cancers. We will test how important these molecules are in the development of cancers in the intestine, and further explore the mechanism of action.
