One step closer to turning off cancer genes with gene-silencing

4 June 2009

Using this technology, Sherry and her colleagues observed a 70% reduction in tumour size in a cervical cancer mouse model.

Strangling tumours in bid to halt cancer

15 May 2009

It may be possible to halt cancer in its tracks by blocking a gene critical to building tumour supply lines, according to new research carried out at the University of Queensland. Most tumours need a blood supply to grow. Researchers at the Institute for Molecular Bioscience have found that when new blood vessels form – [...]

Does my asinina look big in these genes?

15 July 2008

The world’s fastest growing abalone—the tropical donkey’s ear abalone, Haliotis asinina—can be bred to grow rapidly and reliably for aquaculture, Queensland biologists have found.

Clue to anti-male gene action: an extra gene can stop boys being boys

5 July 2008

Researchers at Prince Henry’s Institute in Melbourne have discovered how an extra copy of a gene halts the process of becoming a boy.

Female mice turn male with the help of a brain gene

20 August 2007

Edwina Sutton and colleagues at the University of Adelaide have been busily turning female mice into males.

Are cancer cells confused?

30 August 2004

Scientists have recently discovered that the gene EDD is implicated in the development of breast and ovarian cancer. And like the horse, this gene is into talking. “Cancer arises from defects in cell growth and division. We are now beginning to realise that defective cellular communication can also lead to cancer,” says Professor Rob Sutherland, [...]

New genes mean cleaner, greener, better quality crops

23 August 2004

Two plant genes have been identified that could lead to new crop varieties resistant to fungal diseases, meaning increased productivity for farmers and improved quality and cheaper costs for consumers. These two genes can help plants boost their own immunity to disease, resulting in less need for chemical sprays, improved produce quality and increased shelf [...]

Cause of a devastating immune disease found

19 August 2003

Researchers have shown how mutations in a key gene cause a rare but devastating inherited autoimmune disease – APS-1. They’ve revealed fundamental workings of our immune system – and how our bodies teach our defence systems not to engage in friendly fire.

New gene culprit in clogged arteries and impotence

22 August 2002

Researchers at the Howard Florey Institute have discovered a new gene in the lining of arteries that makes them thicken or crack causing reduced blood flow which may lead to heart attacks, stroke or impotence.

On the trail of breast cancer’s spread to bones

24 August 2001

In break-through research, researchers have identified genes in mice that appear to be important in the spread of breast cancer to bones. Australian women have a one in eleven life-time risk of developing breast cancer. For many women, early diagnosis and treatment provides a complete cure. However, if the tumour spreads, the disease is hard [...]

Slime genes unlock secrets of colon cancer

4 May 2000

Queensland researchers have discovered new genes that are important in producing the ‘slime’ that protects the human colon from cancer-causing agents. Currently about one in 23 Australians are likely to develop colorectal cancer, a disease that attacks the lining of the colon and rectum at the end of the human digestive system.

Mutant Mouse Reveals Key to Brain Disorder

1 May 2000

A  Melbourne scientist has discovered the gene that causes de Morsier syndrome, a severe disorder in which babies are born with underdeveloped brains, eyes and pituitary glands.   Dr. Paul Thomas from the Murdoch Childrens Research Institute has shown that children with this syndrome have a critical change in the Hesx1 gene which causes a malfunction [...]

WCH breakthrough in epilepsy

10 May 1999

Genes & Epilepsy: How do they “fit”? – Robyn Wallace Robyn has identified the first gene known to cause febrile seziures. This is a specific form of epilepsy that affects young children.

Spying on the program of life

10 May 1999

It is now possible to measure what every single gene is doing simultaneously in a cell under a variety of conditions. This enables scientists to say “Eureka! I’ve discovered a million numbers!” Unfortunately, their colleagues reply “And?” Andrew Conway is helping biochemists find meaning in their data.
