Cancer Research Achievements Acknowledged at Clifford Awards Posted on November 25, 2015March 13, 2018 by Carly du Toit The Clifford Prize for Cancer Research was presented to Professor Inder Verma and Professor Jane Visvader at Seventh Barossa Meeting on Cell Signalling in Cancer Biology and Therapy. The bi-annual prize is presented by the Centre for Cancer Biology (CCB), South Australia, for outstanding international achievement in cancer research. Professor Verma is an American Cancer Society Professor of Molecular Biology in the Laboratory of Genetics at the Salk Institute for Biological Studies. He has been responsible for many major discoveries in cancer biology over the past four decades, ranging from basic discoveries regarding transcription factors involved in cancer, laying the basis for modern molecular biology by developing the cDNA synthesis procedure using reverse transcriptase, to development of viral-based vectors for gene therapy approaches to various genetic diseases, including cancers. Professor Verma and co-workers have ingeniously employed specific methods of mouse genetics to reveal the roles of many specific oncogenes / transcription factors in normal cellular growth, differentiation and development. Professor Visvader is a Fellow of the Australian Academy of Science. She and her team have made major contributions to the understanding of breast cancer by isolating mammary stem cells, defining master regulators of mammary gland development and identifying genetic lesions that drive oncogenesis. Her landmark discoveries have revealed master regulators that orchestrate cell fate decisions in the mammary gland, providing an indispensable framework for understanding mammary lineage commitment and differentiation, and a basis for understanding origins of breast cancer. The Clifford Prize for Cancer Research represents an appreciation by Australian scientists for discoveries that have combined outstanding science with significant clinical relevance. The ACRF Cancer Genomics Facility was established at the CCB in 2009, with the assistance of a $3.5m grant from the ACRF.

International gene study identifies five new melanoma risk regions Posted on August 24, 2015March 14, 2018 by Carly du Toit An international study led by QIMR Berghofer cancer researcher, Dr Matthew Law, has uncovered five new gene regions which increase a person’s risk of melanoma. Melanoma is the third most commonly diagnosed cancer in Australia, and although there are effective treatment options available to those who detect it early, the five-year survival rate of patients with more advanced cases is only 10%. “Each day around 30 Australians are diagnosed with melanoma, and from that more than 12 hundred a year lose their battle with the disease,” says Dr Law. “So each little piece of knowledge that we uncover is crucial as it affects the overall picture and helps us to continue to develop and improve the ways we detect and treat it.” The study found five new regions of the genome associated with melanoma and formally confirmed two more that were suspected to be risk factors. This research takes the total number of known melanoma gene risk regions to 20. “Most of the major gene risk regions previously identified are associated with pigmentation, or the number of moles a person has. The five new gene regions we’ve discovered are from different pathways, so it’s yet another piece to add to the melanoma puzzle.” “Out of the new regions that were found, the most interesting biologically, was one involved with the maintenance, development and length of the telomeres. Telomeres are like shoelace caps at the end of each strand of DNA that protect our chromosomes from damage. We know that loss or damage to telomeres is a key factor in the development of cancer cells.” Over 12 thousand melanoma samples were used for the project, making it the largest genome wide association study (GWAS) to identify variations associated with melanoma. The international collaboration of researchers from QIMR and the Melanoma Genetics Consortium (GenoMEL) are now preparing for an even larger study which is expected to find more markers of risk. “Our long term goal is to find drugs that modify the pathways that we’re identifying – that way we’ll be able to alter specific activity and bring it back to normal.” “It’s very exciting to find something new about a serious condition – that’s the joy of doing this kind of research. Working in science is all about discovering new things that haven’t been seen or understood before and hopefully add a bit more knowledge to the world.” QIMR Berghofer Medical Research Institute has received $6.65 million in grants from the ACRF which has funded technology to progress research in colon, breast, ovarian, prostate, leukaemia, lymphoma and melanoma.
