Summary
Diseases, infections and pathologies are common clinical problems of the intestine in humans that can lead to loss of intestinal tissue. Individuals with these conditions can experience nutritional problems and severe cases result in death. Promoting regeneration of the damaged tissue is critical to re-establish intestinal function. In this study, we will examine the regenerative potential of a growth factor called Neuregulin1 in the intestine with the aim of facilitating tissue regeneration.

Summary
Age related changes have been shown to impact on the overall functional properties of the intestinal epithelium, which affects overall nutrition and quality of life in the aged population. This proposal will study the cellular and molecular mechanisms underlying intestine deterioration during aging.
Deciphering The Overlapping Roles Of SSB1 And SSB2 In The Regulation Of Haematopoiesis And Intestinal Homeostasis

Summary
Our work centres on elucidating the role of two newly identified and related single-stranded DNA binding protein (Ssb1 and Ssb2) in development of blood and gut system. When both genes are deleted mice die with 8 days of knockdown due to bone marrow failure and intestinal atrophy. Our double knockout model parallels the consequences of radiation damage on blood and gut system. Toxicity to these systems is a significant hindrance in delivering anti-tumor therapy.
DOES BCL-G, A BH3-ONLY PROTEIN, PLAY A ROLE IN INFLAMMATION-ASSOCIATED COLON CANCER?

Summary
Deregulation of the function of several members of the Bcl-2 family has been shown to be an aggravating factor in autoimmune diseases and cancer. Bcl-G is a new and poorly characterized member of this family. We have produced essential tools to study the physiological function of Bcl-G, and discovered that it plays a role in inflammatory bowel disease. We now plan to investigate its possible role in inflammation-associated colon cancer.?
Role Of Snail Proteins In Mediating Intestinal Stem Cell Identity

Summary
The lining of the intestine is constantly renewed by stem cells which also contribute to replenishment of this layer following damage caused by trauma, infection or treatments such as chemotherapy. We are studying how a family of gene regulators called Snail proteins act to maintain stem cells in the gut. Snail proteins have also been found to be present at high levels in bowel tumours so we are examining their role in the genesis of tumours and resistance to common treatments.
