Targeted Redox Therapy For Photoageing Prevention And Treatment
Funder

Funding Amount
$562,815.00
Summary
Our goal is to target natural reduction/oxidation (redox) modifiers, i.e. niacin and sulforaphane, to the skin deeper layers to treat photoageing. Both drugs have been separately shown to prevent UV induced skin cancer. The outcomes of this project will be safer and more effective prevention and treatment of sun damaged skin. This project can provide health benefits to Australians from improved treatment of sun damage, and economic benefits to the nation.
20 Year Study Of Skin Cancer In A Queensland Community

Summary
Skin cancers are by far the commonest cancers diagnosed in Australia. Even though it is known that sun exposure in excess causes skin cancers there are complexities about the causes, especially of basal cell carcinoma (BCC) -the major type of skin cancer- that are still not understood. Relative intensity of sun exposure and perhaps its timing with respect to age in life may well be critical factors. We aim to study these causes in very great detail by collating information that has been gathered ....Skin cancers are by far the commonest cancers diagnosed in Australia. Even though it is known that sun exposure in excess causes skin cancers there are complexities about the causes, especially of basal cell carcinoma (BCC) -the major type of skin cancer- that are still not understood. Relative intensity of sun exposure and perhaps its timing with respect to age in life may well be critical factors. We aim to study these causes in very great detail by collating information that has been gathered over a 20 year period in a community-based skin cancer study in Nambour, Qld as well as performing some laboratory tests on skin cancer tissue collected from participants. This 3-year project will enable the full realisation of the potential of this esource-20 years in the making- with its wealth of information for answering questions about skin cancer decelopment and preventability. It should finally provide us with a clearer rationale for 'prevention of skin cancer' than is currently available. In addition we shall assess the costs of treatment of skin cancer in general and for the individual, and how much preventive practices for skin cancer might save the health budget, by using the releavnt data collected from this community sample.Read moreRead less
The Role Of Perivascular Macrophages In The Regulation Of Skin Inflammation

Funding Amount
$616,518.00
Summary
Neutrophils are key defenders against bacterial infections. In this application we will test the hypothesis that perivascular macrophages play a critical role in the recruitment of neutrophils to site of cutaneous infection, and that these cells are targeted and destroyed by bacterial virulence factors. Our studies will gain novel insight into the leukocyte homing paradigm and shed new light on the mechanisms of microbial immuno-evasion.
My work on human pigmentation genetics has provided a framework to understand normal variation in this physical trait and the associated genotypic risk factors for skin cancer development. The genes that determine an individual's skin phototype and the ce
Infectious And Lifestyle Determinants Of Non-melanoma Skin Cancer.

Summary
Basal and squamous cell skin cancers are the leading cancers in Australia, with about 2% of the population developing them each year. As well as sun exposure, a number of other factors have been thought to effect these cancers. This study will examine if factors such as smoking, alcohol consumption and infection with certain skin related human papillomaviruses also increase their risk. Even a small effect may make a big difference when it comes to preventing these common cancers.
Modulating Inflammation As A Therapy For Harlequin Ichthyosis

Funding Amount
$718,739.00
Summary
Harlequin Ichthyosis is a severe inherited skin disease caused by mutations in a protein which regulates how skin cells control their levels of lipids. Treatments for this disease are limited and do little to improve patients condition. We believe we have found a new way to treat this condition by altering tissue inflammation. This grant will undertake important experiments aimed at developing new therapies for this currently incurable disease.
Mast cells (MC) are key regulators of chronic skin inflammation, such as atopic eczema, and can also give rise to a group of diseases called mastocytosis. How MC numbers are regulated in these conditions is poorly understood. We have identified a novel circulating precursor cell that gives rise to MC. We will determine the function of these precursors in skin diseases, including eczema and mastocytosis, with the aim to curtail the course of of these difficult-to-treat conditions.
Specific Targeting Of Nanosystems By Cutaneous Delivery

Funding Amount

Summary
Substances have long been applied to the skin for therapeutic or cosmetic purposes, but the range of suitable compounds is limited. Consequently, there is a need for a wider range of compounds which can be delivered effectively into the skin for targeted treatment, diagnostic imaging and vaccination. New nanomaterial drug delivery systems are being increasingly used for these purposes. We seek to understand the properties of nanosystems that will enable improved drug targeting via the skin.

Summary
Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia. We will examine the relationship between the form, structure and colour of existing types of moles and their subsequent risk of developing into melanoma. This will be the first study to combine dermoscopy, a non-invasive examination technique, with DNA tests of the genes that determine skin, hair and eye colour, aiding in the early prediction and diagnosis of skin ca ....Melanoma is a form of skin cancer that arises from the cells that produce pigment and is a major public health issue in Australia.
