The results show changes in gene expression that persist for at least 21 days after finishing a seven-day course of growth hormone which is a vast improvement on the current test that has a window of detection of only 36 hours.
Dr Gray has presented the findings to World Anti-Doping Agency’s Gene and Cell Doping Symposium in Beijing. This stemmed from a one-year pilot project funded by the Australian government’s Anti Doping Research Program to develop a new blood test for the detection of the use of human growth hormone.
“The idea centres on measurement of changes in gene expression in white blood cells which are part of our immune system,” he said, adding that profiling in the detection of growth hormone usage could have direct application for the development a novel anti-doping detection method.
Hosted by the China Anti-Doping Agency and the Beijing Olympic City Development Association, the Beijing symposium examined scientific advances in gene doping research, and in particular focused on latest developments in the use genetic technologies for doping detection.
The Bond University Health Sciences professor has had extensive experience in education, sport, coaching and exercise science and completed a PhD in biochemistry and molecular biology at the Australian National University in Canberra while undertaking research at the Australian Institute of Sport.
Dr Gray and his co-investigator Associate Professor Lotti Tajouri were among a select group of experts from around the world in the fields of scientific research, anti-doping testing and medicine invited to the symposium. Dr Gray commented that since only 20 sports scientists from around the world were invited to the symposium, it made it a very significant gathering of the best research in this specialized field.
“It is a recognition of the work that Bond University has been doing in a number of areas in the field of sports science and adds to the university’s prestige in the overall fields of Health and Medical Science.”
