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.
Identifying The Mechanism Of The G2 Phase UV Checkpoint And Repair Response Commonly Defective In Melanoma

Summary
The UV component of sunlight is the major environmental factor driving the development of melanoma. UV radiation can directly mutate genes resulting in their inability to perform normal functions which may contribute to cancer. Despite the high number of mutations directly attributable to UV radiation, the mechanisms known to repair these mutations are generally normal in melanoma. This research will investigate a repair mechanism we have identified that is commonly defective in melanomas.
Narrow Band UVB Phototherapy For Patients With Clinically Isolated Syndrome: A Phase 1 Trial

Summary
The environment, particularly lack of sunlight exposure, contributes to the incidence and progression of multiple sclerosis. We will give patients with early multiple sclerosis controlled exposure to ultraviolet light and then measure biomarkers of their disease activity over the next 12 months. The therapy is safe and is used for treatment of patients with psoriasis. Patients should gain benefits from sunlight-induced vitamin D, as well as other sunlight-induced molecules.
Pterygia, one of the most common ocular complaints in Australia and worldwide, are thought to originate from overexposure to UV light. We propose that UV-irradiation stimulate certain cells in the eye to produce cytokines, growth factors and enzymes which degrade scaffold proteins such as collagens. These enzymes may play a key role in the progressive and invasive nature of pterygia. Dissecting the mechanism(s) by which UV light induces these proteins will lead to new and more reliable therapies ....Pterygia, one of the most common ocular complaints in Australia and worldwide, are thought to originate from overexposure to UV light.

Vascular Targeting Combined With Radiosurgery In An Arteriovenous Malformation Rat Model

Summary
Cerebral arteriovenous malformations are an important cause of stroke and brain bleeds. In many patients such a stroke can result in severe disability or death. Current management involves a combination of surgery, radiation therapy and endovascular treatments and carry a high risk of complications. This research project suggests a new form of treatment whereby irradiating the vascular malformation a medication could be administered to cause targeted clotting of the malformation.
The Centre for Research Excellence in Sun and Health (CRESH) aims to build an evidence base that will lead to the development of regionally appropriate public health guidelines that will balance the adverse and beneficial effects of sun exposure to optimise the health of the Australian community.
Determining The Impact Of Cytotoxic Therapies On The Bone Marrow Microenvironment

Funding Amount

Summary
Treatments for cancers result in markedly impaired blood cell production. Non-blood cell types within the bone marrow (BM) microenvironment are important to the regulation of blood cell production. We have evidence these cancer treatments also damage the BM microenvironment. We aim to fully explore how cancer treatments impact on the BM microenvironment. We can then determine how to improve recovery of the BM microenvironment in order to rapidly restore blood cell production after treatment.

The prestigious NHMRC grant is intended to support Australian researchers involved in European collaboration, which will benefit the Australian community. Professor Green and her research group will use the grant to participate in a large consortium led by Dr Jan Nico Bouwes Bavinck from Leiden in the Netherlands, with teams of researchers based in Germany, England, Italy and France. The work of the consortium will focus on finding out whether Human Papilloma Virus plays a role in causing skin cancer. Professor Green and her team are working to discover the relationship between Human Papilloma Virus, which is a common virus of the skin and the commonest types of skin cancer. If the papilloma virus is found to cause skin cancer, this will open up new avenues for prevention. Although Australia is a world hot-spot for skin cancer, the disease is of concern to Europeans because it is the most common form of cancer in white-skinned people.Read moreRead less
