The discoveries made to date and the proposed studies point to an intrinsic role for vitamin D compounds in skin in providing protection from sun damage. As a result of sun exposure, increased concentrations of vitamin D compounds in skin will be generated and this is likely to provide protection against further UV damage, in much the same way as increased pigmentation and increased thickness of the outer layer of skin.

As a result of sun exposure, increased concentrations of vitamin D compounds in skin will be generated and this is likely to provide protection against further UV damage, in much the same way as increased pigmentation and increased thickness of the outer layer of skin. Furthermore, the studies are designed to test whether vitamin D compounds which have minimal effects on serum calcium, could nevertheless be used topically in association with a sunscreen or moisturizer to add to sun protection. As Australia has the highest skin cancer rates in the world, this would be of significant health and economic value.Read moreRead less
Is CYP11A1 Critical For The Vitamin D Photoprotective System In Skin?

Summary
Sunlight produces DNA damage. When inadequately repaired, this damage produces skin cancer. The vitamin D system in skin helps protect against this skin damage, but the vitamin D compounds involved and how they work is unclear. Recent data shows new vitamin D compounds with photoprotective activity and that vitamin D compounds increased expression of DNA repair proteins. These studies may enable pharmacological enhancement of protection from sunlight.
The Ghrelin Axis As A Target For Prostate Cancer Therapy

Summary
Prostate cancer affects one in nine Australian men in their lifetime, and although there have been great advances in treatments, advanced prostate cancer remains incurable. Current treatments often lead to side effects which affect quality of life. We have found that the appetite hormone, ghrelin, stimulates prostate cancer cell growth and may be a useful target for prostate cancer therapy. We predict that targeting the ghrelin axis will prevent some of the side effects of other treatments that ....Prostate cancer affects one in nine Australian men in their lifetime, and although there have been great advances in treatments, advanced prostate cancer remains incurable. Current treatments often lead to side effects which affect quality of life. We have found that the appetite hormone, ghrelin, stimulates prostate cancer cell growth and may be a useful target for prostate cancer therapy. We predict that targeting the ghrelin axis will prevent some of the side effects of other treatments that reduce quality of life for patients.Read moreRead less
HEREDITARY ENDOCRINE CANCER: A MODEL BASED ON PHAEOCHROMOCYTOMA- PARAGANGLIOMA SYNDROMES

Funding Amount
$875,894.00
Summary
Phaeochromocytomas and paragangliomas are tumours remarkable for their very high heritability. They have a high burden of disease themselves, and their associated hereditary syndromes include risks for other malignancies. Our study will rationalize the pathological approach to diagnosing these hereditary syndromes, find new therapeutic targets for metastatic disease, and provide a template for other cancers with high heritable component.
The Essential Role Of Androgen Receptor Signalling In Prostate Tumorigenesis

Summary
An urgent objective in prostate cancer clinical practice is to better predict disease course at diagnosis and to identify patients likely to develop metastatic (lethal) disease. We aim to identify clinically-relevant genes - gene pathways that are important in prostate cancer development and progression and which can be used to improve prediction of patient outcome. Prostate cancer management can be improved by tailoring treatments for individual patients.
The Role Of A Protease Activated Receptor System In Prostate Cancer Bone Metastasis.

Summary
Prostate cancer is one of the most significant health issues for men. This disease occurs because certain proteins start to function abnormally. Our focus is on a protein called PAR2, present on the surface of prostate cancer cells and bone cells, which we propose helps cancer cells to spread to bone. In our project, we aim to understand how this happens so that we can develop ways to block prostate cancer metastasis to bone.

Summary
Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population. Survival rates for lung cancer are very poor. We have discovered a new gene that is produced by lung cancer cells and may contribute to the aggressive nature of this disease. We will investigate this gene to determine if it could be a useful target for new therapies for lung cancer and it determine its utility as a biomarker for the severity of t ....Lung cancer is the most common cause of cancer deaths in men and women in the world and the incidence in Australia is rising with our aging population.
