Summary
Skin cancers are the most common human tumours and the incidence is increasing. Ultra-violet (UV) light is the main factor in the formation of skin cancer. This project will find how a gene product (MIC-1) induced by solar UV affects the skin, and why we see it in skin cancers. This protein has other interesting properties that could bear directly on measuring sun exposure and understanding skin cancer.

Ultra-violet (UV) light is the main factor in the formation of skin cancer. This project will find how a gene product (MIC-1) induced by solar UV affects the skin, and why we see it in skin cancers. This protein has other interesting properties that could bear directly on measuring sun exposure and understanding skin cancer. A processed form is released into the blood, where it could carry UV signals and be used in population studies as a measure of sun exposure. It's also induced by certain cancer-promoting chemicals which resemble UV light in their immediate effects. A lot could therefore be learnt from this protein, and if we find that MIC-1 promotes the growth of normal and tumour cells in the skin after UV exposure, we can look for ways to stop this happening.Read moreRead less
Adult non-Hodgkin?s lymphoma (NHL) is one of the most rapidly increasing cancers of recent times. The rise has occurred worldwide in men and women of all ages. The reason for most of the rise is unknown. It has recently been proposed that part of the upsurge may be due to increases in sun exposure which have occurred during the same period. There is some indirect evidence to support this hypothesis. For example, the rate of occurrence of NHL is higher closer to the equator in Australia than it i ....Adult non-Hodgkin?s lymphoma (NHL) is one of the most rapidly increasing cancers of recent times. The rise has occurred worldwide in men and women of all ages. The reason for most of the rise is unknown. It has recently been proposed that part of the upsurge may be due to increases in sun exposure which have occurred during the same period. There is some indirect evidence to support this hypothesis. For example, the rate of occurrence of NHL is higher closer to the equator in Australia than it is in England and Wales, and NHL is diagnosed more frequently among British migrants to Victoria than it is in their homeland. The sunlight hypothesis will be tested by comparing the pattern of sun exposure in Tasmanians diagnosed with NHL during the years 1998-2001 and in a sample of Tasmanians without the disease. tasmania has been chosen because levels of ultraviolet (UV) radiation are low there in all but the summer months, when it approaches the levels of Brisbane, Sydney and Melbourne. There is therefore a greater difference in UV exposure between the most exposed and the least exposed in Tasmania, making it an ideal location to test the hypothesis. The link between NHL and a measure of melanin pigmentation in the skin will also be studied. The incidence of NHL is higher in lighter-skinned ethnic groups than it is in darker-skinned people living at the same latitude, but it is not known whether risk varies within Caucasian populations. A new measure of melanin in the skin, developed at the Menzies Centre for Population Health Research in Hobart, will better allow the effects of skin colour to be studied.Read moreRead less

Summary
Australia has the highest incidence of skin cancer in the world, due to our lifestyle that involves high levels of exposure to sunlight. Skin cancer, including melanoma can be destroyed by the immune system, but sunlight inhibits immunity, enabling skin tumours to grow. Our aim is to determine how sunlight affects the activation of effector anti-melanoma T cells, and their development into memory T cells, and the dose of sunlight required to have this effect.

Skin cancer, including melanoma can be destroyed by the immune system, but sunlight inhibits immunity, enabling skin tumours to grow. Our aim is to determine how sunlight affects the activation of effector anti-melanoma T cells, and their development into memory T cells, and the dose of sunlight required to have this effect. It is unknown whether ultraviolet radiation in sunlight suppresses the activation of effector cells that mediate rejection of skin tumours, or their development into memory cells, or migration of activated-memory lymphocytes into skin tumours. The number of antigen reactive T cells is a key issue for tumour immunity and the aim of many clinical immunotherapy trials is to boost these to levels that can effectively destroy the tumour. It is important to establish whether low doses of sunlight readily achievable during normal living, or only higher exposures received when sunbaking, inhibit the number of these effector T cells, and their migration into skin tumours. It is important to determine whether there is a relatively safe threshold level of sunlight exposure to be able to give better advice on sunlight doses that can be achieved without causing serious deleterious health effects. Also these levels of sunlight may interfere with immunotherapy trials and therefore need to be determined. An additional outcome will be to determine whether chemopreventative agents that enhance recovery from sunlight induced suppression of skin allergies are also protective for anti-tumour immunity. The establishment of procedures for prevention of suppression of anti-tumour immunity may enhance the number of T cells activated by natural immunity or during immunotherapy, thereby improving immune rejection of melanoma.Read moreRead less

Concepts towards the next generation of dye-sensitised solar cells: tandem and plasmonic solar cells. This project aims at exploring the feasibility of novel device concepts to enhance the performance of dye-sensitised solar cells. These concepts include tandem solar cells as well as novel energy relay systems based on the ability of nanoparticles to effectively act as antenna systems that can funnel energy towards a sensitising dye molecule.
