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.
Telomere Structural Abnormalities In Cells Using Alternative Lengthening Of Telomeres

Summary
The continuing growth of cancers depends on their cells being able to prevent shortening of chromosome ends (telomeres). Some cancers, including very aggressive brain and connective tissue tumours, achieve this via the Alternative Lengthening of Telomeres (ALT) process. We have evidence that the telomere structure of normal cells prevents ALT. Here we will examine how the telomere structure of ALT-positive cancer cells is changed, and whether reversing these changes inhibits ALT.
Using Bioengineered 3D Models To Replicate The Tumour Microenvironment In Prostate Cancer

Summary
The research will address the poor prognosis of patients with advanced prostate cancer bone metastasis by establishing a novel 3D bioengineered bone model containing high amounts of fat cells, where cancer cells can relocate. This approach will help identifying the impact of fat cells on cancer cell function, and help determine whether fat cells are legitimate therapeutic targets, ultimately assisting clinicians to select better therapies for prostate cancer bone metastasis.
Cellular And Molecular Aspects Of Mammographic Density As A Predictor Of Breast Cancer Risk In Pseudo-orthotopic Mammatrophic Environment

Summary
High mammographic density (MD), or denser breast tissue on mammogram, is associated with greater breast cancer risk. Despite this, the basis for its increased risk is poorly understood. This study assesses the effect of high density breast tissue transferred from high risk women at time of mastectomy into tissue engineering chambers in mice. Changes in the connective tissue harvested from the chamber were examined with specialized imaging, laboratory stains and molecular analysis.
