Study reveals genes behind brain tumours

29 October 2013
A team of researchers has pinpointed a handful of genes that could drive the formation of medulloblastoma, the most aggressive and frequent form of brain tumour found in children.
The team was led by Professor Brandon Wainwright, Dr Laura Genovesi and Dr Melissa Davis from The University of Queensland’s Institute for Molecular Bioscience.
Professor Wainwright said the 56 genes they had identified provided potential targets for treatment.
“Brain tumours are the most common cause of cancer death in children,” Professor Wainwright said.
“Those who do survive often experience significant neurological, intellectual and physical disabilities as a result of their treatment, which involves surgical removal of the tumour followed by radiotherapy and chemotherapy.
“We clearly need more effective and less invasive options to treat medulloblastoma and improve outcomes for both children and adults with this devastating disease.”
There are four different sub-types of medulloblastoma, each with their own molecular signature.
The researchers identified underlying genetic regulatory networks that were present in all of the sub-types, a discovery that Professor Wainwright said was important in advancing treatments.
“We are now searching for existing drugs that may block these gene networks and act as viable treatment alternatives for medulloblastoma.”
The team, which included researchers from Australia, Singapore, Canada, the United Kingdom and the United States, made the discovery after screening 85 tumours.
The results were published overnight in the highly prestigious scientific journal Proceedings of the National Academy of Sciences USA.
