2015 NEWSLETTER GENETIC EPIDEMIOLOGY OF MELANOMA Our WMI-MIA-University of Sydney team (L-R): Gulietta Pupo, Danielle Gibbs, Elizabeth Holland, Varsha Tembe, Gayathri St George, Caroline Watts, Graham Mann, Helen Schmid, Leo Raudonikis , Svetlana Pianova , Sarah-Jane Schramm (Absent Richard Kefford and Anne Cust) TELOMERES REVEAL MELANOMA SECRETS It’s a pleasure to bring you up to date with our work in the Genetic Epidemiology of Melanoma study. Since the 1980s we have been working together with people who have a family history of melanoma. Since the year 2000, thousands more people joined our study of melanoma in the community – the Australian Melanoma Family Study. Both these projects run concurrently now, with the aim of fully understanding the ways that genes affect our risk of developing melanoma. We work towards this goal in tandem with studies based in Queensland – the Q-MEGA project, so that information from people with melanoma around Australia and New Zealand can be pulled together in the most effective way. out. So we have special mechanisms to keep them at the right length. Cancer cells learn how to misuse them so they can keep growing – without this they would age and die like normal cells. it is not clear how much extra risk is produced and the number of families with these mutations seems to be quite small, we intend to clarify this over the coming year. 2014 has brought more progress in understanding the melanoma puzzle. In every cell, telomeres are the fragile ends of our chromosomes, the big bundles of DNA in which our genes are grouped. Telomeres are hard to replace each time a cell divides, and they can wear Shelterin proteins (See Figure) are part of these protections and telomerase is the protein that does the repair work. In the past year we and others have shown that some melanoma families have inherited a faulty version of the shelterin genes POT1, ACD or TERF2IP [1,2]. While And this is part of a bigger picture. Everyone varies a little in how long their telomeres are. We have recently shown that this tendency is connected to melanoma risk, for the first time in any cancer [3]. So telomeres have a lot to teach us about melanoma! Telomeres protecting our chromosome ends: now implicated in development of melanoma.* *Figure source: Podlevsky, J.D., et al. Nucleic Acids Res. 36: D339-D343, 2007 NEW BUILDING Melanoma research at the Westmead Millennium Institute has been given a boost with the official opening of the institute’s new building in October. The nine-storey complex includes new melanoma research facilities funded by $7 million in grants awarded by the Australian Cancer Research Foundation (ACRF). Located on Level 7 in the Centre for Cancer Research, the ACRF Melanoma Research Laboratories provide state-of-the-art facilities for melanoma research. The melanoma program investigates all its aspects, from risk in families to developing better diagnostic tests and treatments. The new building brings all of WMI’s 11 centres of research - which were previously scattered across six locations on the Westmead Hospital campus together under one roof for the first time. According to WMI Executive Director, Professor Tony Cunningham, the building creates efficiencies and new opportunities for trans-disciplinary research collaboration. “The building encourages interaction and the exchange of knowledge and ideas between researchers who were previously physically isolated from one another,” said Professor Cunningham. “This is enhancing collaborations across disciplines and I believe it will lead to some significant research advances.” In June the Genetic Epidemiology of Melanoma project team relocated to the Centre for Cancer Research.* “For the first time we have our entire melanoma team in one place,” said Professor Graham Mann. “This has already made every aspect of our work easier, and we can now really take advantage of the excellent research environment in WMI.” *Formerly the Westmead Institute for Cancer Research THE MELANOMA HIGH RISK CLINIC Melanoma High Risk Clinics (HRC) have been established under Cancer Institute NSW (CINSW) Translational Research Program funding to trial a program of computer-assisted photographic monitoring that aims to detect melanoma efficiently at an early stage. Clinics are currently operating at Royal Prince Alfred Hospital, Melanoma Institute Australia, Newcastle Skin Check and recently opened at Westmead Hospital. These research clinics are free to attend but places are restricted to those who have: • had two or more invasive melanomas • had at least one invasive melanoma as well as Dysplastic Naevus Syndrome • had at least one invasive melanoma as well as three or more relatives who have had melanoma • been diagnosed as carrying a family mutation in a known melanoma gene, whether or not they have had melanoma (NB they must have attended a family cancer clinic or genetic counsellor and have had clinical genetic testing). A major report on our first five years experience was published earlier this year: Moloney, F., et al., Detection of primary melanoma in individuals at extreme high risk: a prospective five-year follow-up study.

In 2011 we showed for the first time that solarium use was a cause of melanoma in Australia. Furthermore, the increased risk was strongest in young people. Among solarium users we estimated that about three quarters of the melanomas occurring before the age of 30 were due to sunbed exposure. By January 2015 bans on sunbeds will have come into effect in New South Wales, Queensland, Victoria, Tasmania and the Australian Capital Territory. Western Australia and the Northern Territory are currently debating this issue. UV AND NAIL VARNISH There has been concern about the UV exposure to fingers when curing nail varnish in nail salons. Evidence about the safety of the practice is lacking at the moment, although the UV used is similar to that in solariums, the total dose received by the fingers is quite small. A recent letter in JAMA Dermatology 150 (7), 2014 expressed the situation well: “Although the in vivo risk from multiple manicure visits remains untested, our data suggest that, even with numerous exposures, the risk for carcinogenesis remains small. That said, we concur with previous authors in recommending use of physical blocking sunscreens or UV-A protective gloves to limit the risk of carcinogenesis and photoaging.” http://archderm.jamanetwork.com/article. aspx?articleid=1862050finsuranc CHECKING YOUR SKIN Checking your skin regularly for melanoma is essential for early detection and can be lifesaving. Here is a useful guide: http://www.melanoma.org.au/about-melanoma/ detection-and-screening/checking-your-skin.html LIFE INSURANCE AND OUR RESEARCH In Australia, the life insurance industry has agreed that it will not require people to have DNA tests before taking out life insurance. However, if individuals have had DNA tests, they must report the results in their life insurance application. DNA results from research projects only have to be declared to insurers if the participant in the project is informed about their individual results. http://www.nhmrc.gov.au/_files_nhmrc/file/your_health/ genetics/g001_genetic_discrimination_131120.pdf HOW ARE WE FUNDED?
