Genetic sequencing in Australia could revolutionise cancer diagnostics Posted on June 12, 2015March 14, 2018 by Carly du Toit It is being called ‘the frontier of medical science”’. The potential to pre-empt cancer diagnosis with genetic testing has taken a major step forward following the first Australian NATA* accreditation for ‘whole exome sequencing’. SA Pathology’s Genetics and Molecular Pathology laboratory, in collaboration with the Centre for Cancer Biology’s ACRF genomic research facility, have received this important stamp of approval to test the complete set of human genes in a single assay, using cutting-edge Next-Generation Sequencing (NGS) Technology. Professor Hamish Scott, Director of the ACRF Cancer Genome Facility at SA Pathology’s Centre for Cancer Biology explains: “In human DNA there are six billion data points, 2% of them are our genes, which can be sequenced in an ‘exome’. We’re searching through over a hundred million bases to try and find an anomaly or a mutation that may be causing disease.” This landmark accreditation rewards many years of research dedication and collaboration between research and funding bodies, including the Australian Cancer Research Foundation. Dr Karin Kassahn, Head of Technology Advancement says, “With this new approach, genetic tests will take months, not years, and see an end to some of the uncertainty – there will be definitive results for more patients.” “These technologies weren’t available a decade ago, but now genomics is set to play a major role in medical treatment. If we get this right, genetic testing will become an integral part of health care, available to everyone in need.” Professor Scott has said that unfortunately many rare genetic conditions still don’t have an effective treatment or cure. “But if we can pick these things up, we may be able to alleviate symptoms with new therapies and help patients and families manage their disorders,” he said. “This is the future of healthcare, what’s known as ‘personalised’ or ‘precision’ medicine.” The ACRF is proud to have supported the world-class research teams at SA Pathology, Centre for Cancer Biology. We thank our donors and fundraisers for their dedication to cancer research, without which, this important progress would not have been possible.

It ensures facilities, testing and measurement methods comply with relevant international and Australian standards.
World-first research centre signifies a new era for cancer research Posted on May 22, 2015March 14, 2018 by Carly du Toit The Australian Cancer Research Foundation Telomere Analysis Centre officially opened its doors this week to become the world’s first facility to specialise in Telomere research. Recent findings argued a strong case for the development of this cutting-edge facility, indicating Telomeres could hold the answers to significant advancements in the treatment of some of the most aggressive types of cancer. Telomeres are structures that cap the ends of our chromosomes. They serve a critical role in the cell renewal process and under normal conditions, gradually shorten as we age. But studies at the Children’s Medical Research Institute have shown that cancer cells develop ways to disrupt this natural process. They re-program cells to prevent their telomeres from shortening, causing the DNA to “short-circuit” and cells to multiply out of control. Furthermore, researchers have found ‘lock’ mechanisms on normal cancer cells which prevent this process. The ‘lock’ on cancer cells, however, is damaged, providing researchers with a new target for treatment. CMRI Director, Professor Roger Reddel, who was involved in the research, said “We think that losing this lock makes cancer cells vulnerable to treatments that normal cells are protected against. So we may have found an Achilles heel for certain types of aggressive cancer.” “The ACRF’s Medical Research Advisory Committee assessed this research initiative as both nationally ground-breaking and internationally competitive. The ACRF and our supporters are very proud to fund this life-saving work at CMRI,” said ACRF Chief Executive, Professor Ian Brown. The new ATAC facility was funded with a $2 million ACRF grant and is outfitted with some of the most advanced technology and cutting-edge equipment that exist in this field. These microscopes and computer analysis stations provide speed and accuracy on unparalleled levels, helping to propel telomere-related cancer research to new heights and accelerate the race toward new treatments, and ultimately, cures for cancer.
