"But with γ-T3, QUT researchers have found a better way to treat prostate cancer, which has the potential to inhibit recurrence of the disease."
Dr Ling said in animal trials, γ-T3 completely inhibited tumour formation in more than 70 per cent of the mice implanted with prostate cancer cells and fed the vitamin E constituent in water. In the remaining cases, tumour regrowth was considerably reduced, while tumours reformed in 100 per cent of the control group.
The findings were published recently in the International Journal of Cancer.
The next stage of Dr Ling's study has begun and will determine the long-term effectiveness of the γ-T3 treatment, with plans to progress to clinical trials in the future.
"Previous clinical trials using another vitamin E constituent to inhibit prostate cancer development were unsuccessful, but these trials did not use the vitamin E constituent γ-T3," he said.
"Other research has found γ-T3 is also effective in suppressing other types of cancer, including breast, colon, liver and gastric."
Dr Ling said while not all vitamin E preparations had the active constituent, natural vitamin E obtained from palm oil was rich in γ-T3.
Professor Ross Young, from QUT's Institute of Health and Biomedical Innovation (IHBI), said one of TRI's greatest strengths was to bring together leading researchers.
"Collaboration, which combines the expertise of researchers from different disciplines and institutions to achieve common goals, will lead to better solutions," Professor Young said.
QUT Vice-Chancellor Professor Peter Coaldrake said TRI would greatly benefit Queensland's and Australia's economy and ability to attract the world's best researchers to our shores.
"By having this world-class facility producing research of the highest quality, we will be increasing Queensland's international competitiveness in research," Profe
