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.
Rob Ramsay has had a long standing research commitment to understanding bowel and breast cancer using mouse models with defined genetic defects. These sophisticated models replicate various stages of cancer development and some have profound effects on normal tissue biology. He also uses molecular tools to investigate how genes are controlled. These approaches are providing direct input into the development of therapeutic agents for cancer treatment.
Cancers of the skin are the most common tumours in humans, and their diagnosis and treatment impose the largest costs on Australia’s cancer budget. While much has been learned about the roles of sunlight and skin type as risk factors for skin cancer, relatively little is known about the genes conferring risk. This study will compare the genetic profiles of over 6000 patients with skin cancer to 3000 people without skin cancer to pinpoint the genes responsible for skin cancer.
Microparticles As Novel Biomarkers In Liver Cancer

Summary
No current highly sensitive or specific diagnostic and prognostic biomarker for hepatocellular carcinoma (HCC) exists. We will identify novel nucleic acid signatures in the circulation of patients with HCC through Next Generation Sequencing. Plasma microvesicles will be isolated and their contents analyzed to identify novel genetic biomarkers and fusion gene constructs specific for HCC. Resultant panel of novel biomarkers for HCC will be validated on the Australian STREP cohort of HCC patients.

Summary
squamous cell carcinomas of the skin are the second most common skin cancer. In this proposal we present data showing that a new gene, E2F7, may play an important role in the development of squamous cell carcinoma. If true, these studies will identify a new therapeutic target that could be exploited in developing novel anticancer therapies.
Kidskin: An Intervention To Reduce Sun Exposure In Children

Summary
Melanoma is an important public health problem in Australia. Almost all melanoma is caused by exposure to sunlight, and childhood exposure appears to be particularly important. Thus, if we can reduce childhood exposure, we should ultimately be able to reduce the incidence of melanoma. Despite nation-wide campaigns such as SunSmart, children in Australia still get too much sun exposure. The school offers an ideal opportunity for implementing sun-safety campaigns in children. In 1995, we began the ....Melanoma is an important public health problem in Australia. Almost all melanoma is caused by exposure to sunlight, and childhood exposure appears to be particularly important. Thus, if we can reduce childhood exposure, we should ultimately be able to reduce the incidence of melanoma. Despite nation-wide campaigns such as SunSmart, children in Australia still get too much sun exposure. The school offers an ideal opportunity for implementing sun-safety campaigns in children. In 1995, we began the Kidskin study, which aims to develop, implement and test a school-based program to reduce sun exposure. Preliminary data from the study show that we successfully reduced exposure. However, we are not certain that we have reduced their risk of melanoma. To see if we have reduced the risk of melanoma, we are counting the children's moles. Moles are strongly related to melanoma, and are our best way of measuring actual risk of melanoma. If we are successful, it will be the first time anyone has shown that reducing exposure to sunlight during childhood will lead to a reduction in the incidence of melanoma in later life.Read moreRead less
The Molecular Basis For The Initiation Of Squamous Differentiation And How It Is Disrupted In Oral Cancers

Summary
Squamous cancers of the mouth, nose and throat occur due to defects in the cells that line these regions. We have shown that a major defect is that the lining cells are unable to stop growing and mature into cells that provide a barrier against the environment. In this proposal we will undertake studies to identify why these cancers cells do not mature properly. In doing so we will be able to identify new strategies that may be used to treat patients with this frequently deadly cancer.
