The incidence of melanoma in Australia continues to increase, with Queensland having the highest incidence worldwide. This research uses latest advances in genomics, imaging technologies and microbiopsy devices to develop a personalized screening program for high-risk individuals, with the aim of improving early detection, and reducing the burden of melanoma.
Treatment for skin cancer costs the Australian healthcare system >$1 billion annually. Early detection and accurate diagnosis of melanoma improves survival, however a standardised approach to diagnosis does not currently exist. This study will prospectively recruit 15,000 patients to develop and validate a risk stratified image-based approach to melanoma prevention, early detection and surveillance which will incorporate cutting edge technologies to standardise diagnosis and optimise care.
Many products are applied to the skin to prevent skin cancer or to treat skin diseases. This project seeks to better understand how we can make such products more affective, safer and appropriate for conditions such as psoriasis. One major component of the grant is concerned with the evaluation of nanotechnology products applied to the skin.
Skin cancer affects 60% of Australians. Nicotinamide (vitamin B3) prevents many of sunlight’s damaging effects and reduces premalignant keratoses by 35% compared to placebo in sun-damaged individuals. We now need to test whether nicotinamide can prevent skin cancer. Skin cancer patients will receive nicotinamide or placebo for 12 months and new cancers will be counted in each group. Nicotinamide is safe, widely available and an exciting opportunity for cost-effective skin cancer prevention.

To Describe The Regional Differences In The Innate Immune System Of The Skin Using Intra-vital Multiphoton Microscopy And Understand Its Functional Consequences In A Cutaneous Parasite Infection Model.

Summary
This study is the first of its kind to map the innate immune system, the body's first line of defence, in the skin - coined the "immune atlas". Researchers have shown regional differences in innate immune cells which could explain how infections develop at different sites of the body. Although they have shown this in a cutaneous leishmaniasis model, a parasite endemic in most parts of the world, it may have implications also for inflammatory skin conditions such as eczema or psoriasis.
Muir Torre Syndrome: The Role Of IHC And Genotyping In Sebaceous Neoplasia To Facilitate Prevention Strategies In Colorectal And Endometrial Cancer

Summary
Sebaceous neoplasia (SN), may be an early warning sign for Lynch syndrome (LS), an inherited cancer predisposition caused by mutations in a group of genes. There are high lifetime risks of bowel and uterine cancer, for which there are effective risk management plans if the risk is known. Clinicians are challenged by the role of SN in identifying LS. At present, it is hard to differentiate. We aim to determine features to improve the diagnosis of LS carriers.
Atopic dermatitis (AD) or atopic eczema is the third condition making up the atopic triad (asthma, hayfever and eczema). It usually has its onset before two years of age. It is common, affecting approximately 10% of Australian children and 7% of Australian adults, and is increasing in prevalence. As with asthma, genes are known to be important in its causation, and several different genes have been reported to be involved by different investigators.

It usually has its onset before two years of age. It is common, affecting approximately 10% of Australian children and 7% of Australian adults, and is increasing in prevalence. As with asthma, genes are known to be important in its causation, and several different genes have been reported to be involved by different investigators. These findings are not always repeatable in different countries or ethnic groups. One, the mast cell chymase gene seems to be associated with AD in Japan, but not in Australia or Italy. However, this gene may be responsible only for AD where total serum Immunoglobulin E is low, roughly 20% of all AD. Therefore, the previous studies may not have included enough cases of this subtype to reliably detect the association. The present study aims to test all the published genes in two panels of families: one where both AD and asthma or hayfever are present in the family (180 families), the second where AD alone is present (100 families). We will also test for genetic linkage to particular regions of the genome, where the specific gene is yet to be identified, and for newly discovered gene variants in these regions that may be associated with AD. Confirming and refining the nature of genes involved in the causation of AD is useful for the basic understanding of biochemical pathways to disease and ultimately to the design of drugs to interfere with these pathways.Read moreRead less

Summary
The protective outer layers of the skin known as the epidermis belongs to a group of tissues in the body that are turning over at a rapid rate. The majority ofepidermal cells have a lifespan of just 2-3 weeks, and are shed as mature cells from the skin's surface. These cells are replaced by continuous cell regeneration which is dependent on growth factors and adhesive molecules (and other signals).

The majority ofepidermal cells have a lifespan of just 2-3 weeks, and are shed as mature cells from the skin's surface. These cells are replaced by continuous cell regeneration which is dependent on growth factors and adhesive molecules (and other signals). It has recently come to light that the connective tissue of the skin i.e. the dermis, which lies directly below the epidermal cells has a critical role in providing some of these factors required for their growth and maturation. Indeed, it is becoming increasingly clear that the epidermal and dermal cells co-operate to regulate epidermal proliferation and maturation. Recent work from our laboratory has shown that a newly recognised adhesive protein laminin-10 may be produced as the result of such co-operation and that it stimulates the growth of both normal and tumour epidermal cells. We have also recently identified an interesting subset of dermal cells that may have a role in promoting the growth of the epidermal cells. Thus, the aims of the proposed stuides are to investigate the role of laminin-10 and this specific dermal cell subset in epidermal proliferation and maturation. These studies may also provide an insight into the role of these factors in skin cancers.Read moreRead less
