Summary
Normally DNA exists as a double helix where two strands are zipped together. When single-stranded (ss) DNA is exposed during various cellular processes it can be easily damaged and degraded by cellular enzymes, but is protected by ssDNA binding proteins (SSBs). We have identified two new SSBs (SSB1 and SSB2) that play a crucial role in DNA repair and will investigate the role and physiological function of these important proteins.

Summary
Exposure to both endogenous products of metabolism as well as a variety of exogenous agents (UV, X-rays) increases the risk of cancer and other diseases. This project is designed to further investigate a novel defect in the Rad50 gene that predisposes to genetic instability and cancer. In short we have described for the first time a patient with a defect in the Rad50 gene. This information will assist in understanding our defence systems against oxidative stress to reduce the risk of disease.
Structural And Biochemical Investigation Of The Bloom�s Complex, Defective In Bloom�s Syndrome

Summary
Bloom�s Syndrome is a rare inherited disorder that results in greater than 90% risk of developing cancer by the age of 25. The gene that causes Bloom�s Syndrome, called BLM, protects cells from cancer-causing mutations hence affected individuals develop the same types of cancers as the general population, only much faster. We will investigate the properties of the BLM gene product and understand how it protects us from cancer, and may influence some forms of cancer treatment.
Defining Biomarkers Of Colorectal Cancer Prevention By Dietary Agents And Translation To Human Intervention Studies

Summary
This research will explore dietary agents for their ability to regulate the damage to DNA that is responsible for causing bowel cancer. The plan is to identify a dietary approach that will effectively reduce the risk of colon cancer. The science will be tested in animal models followed by initial human experiments aimed at testing the relevance to humans.
