Summary
Inflammatory bowel disease (IBD) is a debilitating, chronic condition that often affects patients in the primes of their lives. A limited number of treatments are currently available for these patients and those that are available often have serious side effects, including growth restriction in children. Ghrelin is a natural hormone that has been shown to suppress many features of IBD. This project will investigate the potential of ghrelin as a new treatment for inflammatory bowel disease.

Summary
The appendix has been regarded as a useless organ, however, there are evidence showing its removal reduces the risk of developing inflammatory bowel disease. We have shown that this may be due to altered intestinal immune regulation. The project plans to explore the mechanisms responsible for this altered immune regulation. With knowledge of specific elements of disease causation gained from these studies, more effective and targeted treatment options will become available.

Summary
Programmed cell death, or apoptosis, is required for the removal of infected, damaged or unwanted cells and its disrupted regulation is implicated in cancer, autoimmunity and degenerative disorders. The Bcl-2 family of proteins are key regulators of apoptosis. We propose to generate several mouse models to better understand the relationships between the different members of the Bcl-2 family in an effort to control this pathway for therapeutic purposes.
The majority of stroke results from focal brain infarction, followed by substantial secondary excitotoxic damage in the surrounding areas. Tau has been shown to contribute to excitotoxicity and neurodegeneration in mouse models of Alzheimer’s disease (AD). Preliminary data show that tau reduction also protects against excitotoxic damage after experimental stroke. We aim to dissect the molecular mechanisms of stroke using a tau-deficient mouse model.

Summary
Malaria is estimated to cause 1.2 million deaths per year. The malarial parasite has developed resistance to most drugs and new drugs are needed. We aim to mimic the protective red blood cell diseases common in human populations in malarial endemic areas by identifying host targets that are important in parasite growth.
TAF8 is a small protein that is associated with the general transcriptional apparatus. TAF8 is not an essential part of the general transcriptional machinery, but rather a regulatory molecule that appears to dictate how the machinery is used to express different genes. The absence of TAF8 leads to expression of genes controlling cell death. Since the avoidence of cell death is essential to the development of cancer these results will lead to a better understanding of how cancer develops.
Molecular Regulation Of Pluripotency In The Mammalian Germline

Summary
Germ cells generate sperm in males or oocytes in females. In males, germ cell numbers are tightly controlled in the embryo, with too few germ cells causing infertility, and unrestrained germ cell numbers leading to testicular cancer. We have discovered a molecular mechanism that regulates germ cells in the embryo, and propose to study in mice how this regulation is accomplished and the consequences of defective regulation, in order to learn more about how infertility and testis cancer arise.
